DFS Dictionary: Daily Fantasy Sports Terms To Know

If you have ever sat in a DFS chat and watched someone type "fading the chalk into a punt for leverage in GPPs, but cash leans the safe stack," and thought "I understood maybe three of those words," this DFS dictionary is for you. Daily fantasy sports has its own language, and the lingo flies fast on every slate. The good news is that almost none of it is complicated once someone defines it in plain English and shows you how it actually gets used.

I have been playing and writing about daily fantasy sports for years, going back to the Awesemo.com (now Stokastic.com) days, and the terms below are the ones I use every single day. This is meant to be a reference you bookmark and come back to. Hit CTRL + F, jump to the term you need, read the one-line definition plus a real example, and get back to building lineups. I have grouped the most important strategy terms first because those are the ones that actually move your win rate, then run the full glossary alphabetically.

In Summary (TL;DR)

• DFS means daily fantasy sports. Almost every other term sits on top of the two big format buckets: cash games (beat about half the field, prize safety) and GPPs / tournaments (top-heavy payouts, you need a ceiling).
• The five terms that matter most for winning money: chalk, ownership, leverage, stacking, and variance. Learn those cold and most of the rest fall into place.
• Cash And GPPs Need Opposite Builds. Cash wants floor and safety. GPPs want ceiling, correlation, and ownership leverage. Never fire the same lineup into both and expect it to be optimal in both.
• In my daily workflow the tool surfaces the field before I ever lock a lineup: Stokastic Ownership Projections and Top Stacks show me where lineups are concentrating, and I build and stress-test in the Sims so I am optimizing for how often a lineup actually wins its contest, not a single static projection.
• Glossary covers everything from bankroll to viable, each with a definition and, where it helps, an example.

The DFS Terms That Actually Win You Money

Before the full alphabetical glossary, these are the handful of daily fantasy sports terms I would make sure a new player understands first. Knowing what "rake" means is useful. Understanding chalk, ownership, and leverage is what separates a player who breaks even from one who wins tournaments. Almost all of them trace back to one fork in the road: the format you are playing. Cash games and GPPs reward opposite builds, so before anything else, here is the split I keep in my head.

The row I always point new players to is the last one. In cash you are trying to be right often; in a large-field GPP you are trying to be right big, and you accept that most of your lineups miss. Fire the same build into both and you are, by definition, wrong in one of them.

Chalk And Ownership

Chalk is a player, team, or game projected to be highly owned by the field. Ownership (or projected ownership) is the percentage of lineups in a contest that are expected to roster a given player. These two ideas are the foundation of tournament strategy, because in a GPP your score only matters relative to the field.

Here is the mechanic that took me a while to internalize. If a player is in 60% of lineups and goes off, you barely gained ground, because most of your competition has him too. If a player is in 8% of lineups and goes off, you leap the entire field. That is why I never build a tournament lineup without first pulling up projected ownership. The first column I pull is Stokastic Ownership Projections, which puts a projected ownership percentage next to every player, so I can see the field read before I decide where to be different.

The one habit that matters most: never lock a tournament lineup before you have looked at projected ownership. A 45% chalk play and a 12% pivot can project within a point of each other, but only one of them jumps the field when it hits.

Leverage, Fade, And Pivot

Leverage is taking a lower-owned player who is close in projection to a popular one, so that when your guy hits, you gain ground on everyone stuck on the chalk. Fading is having less of a player than the field. Pivoting is switching off a high-owned option to a similar-priced, lower-owned one to gain that leverage.

A concrete one from NBA. Say the field is piled onto a popular point guard at 35% ownership, and a different guard in the same price tier projects nearly as well at only 10% ownership. Pivoting to the 10% option is a leverage play. You are not punting projection, you are buying field-relative upside. I find these spots by sorting the player pool by projection and ownership side by side, then leaning on simulation. The Stokastic Sims run the contest against a modeled field tens of thousands of times over, and the tool finds which pivots actually raise my lineup's win probability, so I am chasing a measured edge rather than a hunch. For the game-theory behind why a 10% pivot beats the 35% chalk in a big field, our NBA DFS leverage and game theory guide goes deeper.

Stacking And Correlation

Correlation is a statistical relationship, positive or negative, between two players' outcomes. Stacking is rostering a group of correlated players from the same team or game to raise your ceiling. This is the single most important construction concept in tournaments.

The classic example is an MLB team stack. When a team has a big inning, multiple hitters score at once, so their fantasy points are positively correlated. Rostering, say, three or four hitters from the top of a strong lineup means when that team erupts, your whole stack erupts together. Picking which teams to stack and keeping the hitters near each other in the batting order is exactly what the Stokastic Top Stacks tool and the Sims handle for you. The tool ranks the highest-ceiling team stacks for the slate, and the Sims factor the batting-order correlation in automatically, so your stacked hitters do not end up randomly scattered across the order. If you want the full construction rules, our NBA DFS stacking strategy guide carries the same logic across to the hardwood.

Variance, Ceiling, And Floor

Variance is the swing in outcomes that is baked into DFS. Ceiling is the realistic high end of a player's fantasy output. Floor is the realistic low end. Tournaments reward ceiling. Cash games reward floor.

This is the term new players underestimate most. Daily fantasy is high-variance, MLB especially, and the best pre-lock lineup can still finish near the bottom on any given night. That is not a flaw in your process, it is the game. The way I keep my sanity is to judge myself on process over results across a large sample, size my entries so a cold streak does not bust my account, and let the Sims show me the full range of outcomes for a lineup instead of one point estimate. If you have ever wondered why DFS swings feel wilder than a straight bet, our DFS variance vs. sports betting breakdown puts real numbers to it.

DFS Dictionary: The Full Glossary Of Daily Fantasy Sports Terms

Everything below is alphabetical. These are the daily fantasy sports terms to know, with a definition and an example wherever an example makes it stick.

A To C

Balance. Building a lineup of mostly mid-priced players rather than a mix of expensive studs and minimum-salary scrubs.

Bankroll. The total amount of money you have set aside to play DFS. The number one rule of staying in the game is to only play with money inside this bankroll and to size entries as a small fraction of it.

Buy-in. The cost to enter a contest, also called the entry fee. A $3 double-up and a $20 Milly Maker seat are both buy-ins; sizing yours as a small fraction of your bankroll matters more than the sticker price.

Cash Game. A contest that pays out evenly to a large portion of entries, often up to half. Double-ups, 50/50s, and head-to-heads are cash games. The goal is a safe, high-floor lineup that beats roughly half the field, not a tournament-winning ceiling.

Ceiling. The realistic maximum fantasy output you can expect from a player. The driver of tournament rosters.

Chalk. A player, team, or game projected to be highly owned. Example: "That ace at home against a weak lineup is the chalk pitcher tonight, he will be in most lineups."

Contrarian. A play that goes against the field, a player the public is overlooking or who projects low in ownership. Contrarian plays are how you differentiate in large tournaments.

Correlation. A statistical relationship between two players' or data points' outcomes, positive or negative. The foundation of stacking.

D To F

Dart Throw. A longshot play with a thin path to a big score, worth a look in tournaments precisely because it will be low-owned if it hits.

Deposit Bonus. Money a DFS site credits to your account based on your first deposit, usually released in increments as you play.

DFS. Daily fantasy sports. You will see this everywhere.

Diversify. Spreading risk across multiple lineups, games, or players rather than concentrating everything in one position. In multi-entry play, diversifying your correlated exposure beats jamming the same build over and over.

DK Points. DraftKings points, the fantasy points scored under DraftKings' default scoring system.

Double-Up. A cash contest where you roughly double your entry fee by finishing in the top half.

Entry Fee. The cost to enter a contest. Same thing as the buy-in.

Exposure. How much of a given player you hold across all your lineups, expressed as a percentage. Example: "I am at 30% exposure to that point guard tonight." Controlling exposure is the whole point of the Sims' exposure settings.

Fade. To roster a player, team, or game less than the field does, whether for matchup, leverage, or a read on the spot.

FDPs. FanDuel points, the fantasy points scored under FanDuel's default scoring system.

Field Size. The number of entries in a contest. Bigger fields mean more variance and a more top-heavy payout structure.

Fish. Slang for an inexperienced DFS player. You want to be in pools with more of them, not be one.

Flex. The utility roster spot that accepts a player from more than one position, giving you flexibility in construction.

Floor. The realistic low end of a player's fantasy output. The driver of cash-game rosters.

Freeroll. A tournament with no entry fee that still pays real prizes. Free expected value, and almost always worth entering when one lands in your lobby.

Full-PPR. One full fantasy point per reception, DraftKings' default football scoring.

G To L

Game Script. A projection of how a game will actually unfold and what that means for player usage. Example: "Two pass-heavy offenses with a high Vegas total point to a game script full of passing volume, which lifts the quarterbacks and receivers."

GPP (Guaranteed Prize Pool). A tournament type whose name refers to the operator committing the full stated prize pool up front, regardless of how many entries come in. That commitment is on the prize pool itself, not on any payout to you as an entrant. If entries fall short of covering it, the operator adds money out of pocket, which is called Overlay. Payouts are top-heavy, so you want a high ceiling and a differentiated build.

Grinder. A player who grinds lower-stakes, higher-volume contests for a steady return rather than chasing big scores. Most nights I am closer to a grinder than a one-lineup dreamer, and I am fine with that.

GOAT. Greatest of all time. Pure slang, used about players and sometimes about a glorious lineup.

Half-PPR. One half fantasy point per reception, FanDuel's default football scoring.

Head-to-Head. A cash contest where you face exactly one opponent.

Hedge. Taking a position that offsets risk on another position you hold, to lock in a steadier overall result. Example: "Once both of my tournament teams reached the final, I hedged by entering a lineup built around the opposing stack so I was covered either way." Note that hedging reduces variance, it does not eliminate risk.

High-Stakes. Contests with larger entry fees, typically populated by sharper, more experienced players. Tougher pools.

Late Swap. Swapping players into or out of a lineup after the slate's first game has locked, as long as their game has not started. This is the highest-value in-slate action there is. If a player gets ruled out or a batting order changes, late swap lets you react. I keep the Live Before Lock read and late-swap tools open right up to lock for exactly this reason, and our DFS late-swap guide walks through the full in-slate playbook.

Lean. Which way you are currently favoring between two close options. Example: "My lineups lean the cheaper big man over the pricier one, but it is close."

Lineup Lock. The moment lineups freeze for a slate. After lock, your only lever is late swap on games that have not yet started.

Live Final. A live, in-person championship event run by a DFS operator. You earn a seat by winning a qualifying tournament.

M To P

Min Salary. The lowest salary a player can carry on a given site, often around $3,000 on a DraftKings main slate. Minimum-priced players are the raw material for punts.

MME. Mass Multi-Entry, the strategy of entering the maximum allowed number of lineups into a contest. MME players lean hard on bulk tools to build, diversify, and manage exposure across hundreds of lineups. The Sims are built for exactly this, generating large lineup sets under your rules and exposure caps.

Multi-Entry. Entering more than one lineup into a contest. Always check the contest's entry limit before you commit.

Optimizer. A tool that generates multiple lineups based on your rules, projections, and exposure settings. This is core to MME play. I build with the Stokastic Sims: rather than spitting out the single highest-projected lineup, the Sims run a modeled field and surface the builds with the best win probability, then mass-produce them with my exposure controls applied.

Overlay. When a contest's committed prize pool exceeds the entry fees collected, meaning the operator is adding money out of pocket. Overlay is positive expected value for entrants, so it is worth chasing.

Pay Up. Allocating more salary to a higher-priced player, usually at the expense of going cheaper elsewhere.

Pivot. Switching from one player to a similar-priced alternative for a reason, often to gain ownership leverage. Example: "I pivoted off the high-owned forward to a lower-owned one in the same tier to get over the field."

Player Prop Bet. A sportsbook line on a single player's statistical performance. Props and DFS projections inform each other, and the Stokastic prop tools blend market data with projections. Our guide on player props for DFS players shows how to read one against the other.

Point/$ (Points per Dollar). A player's fantasy points divided by their salary, a quick read on salary efficiency.

Prize Pool. The total prizes available to be paid out in a contest.

Punt. Rostering a cheap, low-salary player with a real but unlikely path to a usable score, in order to free up salary for studs elsewhere. Example: "I will punt the $3,000 wing who just moved into the starting lineup so I can pay up to an $11,000 stud at two other spots."

Q To S

Qualifier / Satellite. A smaller, cheaper tournament whose prizes are seats into a larger, more prestigious one. It is my favorite way to take a shot at a big contest without paying full freight for the entry.

Quintuple Up. A contest that pays five times your entry fee to those who cash.

Rake. The cut the operator keeps from a contest's entry fees. Example: if entries total 4,000 dollars and the contest pays out 3,600 dollars, the rake is 400 dollars, a 10% cut. Lower rake is better for your long-term return, which is why our DFS contest selection guide treats picking the right room as its own edge.

Rakeback. A loyalty rebate that returns some of the rake an operator collected from you.

Reach. A play that is an unlikely outcome relative to a player's realistic expectation. Usually said as a caution.

Recency Bias. The tendency to over-value a player because of a few recent strong games and over-fade one after a few weak games, ignoring that variance produces both. Fighting recency bias is where projections beat gut feel.

Regression (to the Mean). The tendency for an over-performing or under-performing player to drift back toward their true expected level over time. A core reason I trust projections over a hot or cold streak.

ROI. Return on investment, your profit relative to the money you put in. The number that actually grades your DFS year.

Roster. As a verb, to put a player in your lineup. "I am rostering that shortstop in my main stack tonight."

Shark. A highly skilled, experienced player. The opposite of a fish. High-stakes pools are full of them.

Single-Entry. A contest where each player may enter exactly once, leveling the field against MME players.

Sleeper. A lightly-owned player the field is overlooking who makes a strong tournament play.

Spread. The expected scoring margin between two teams set by oddsmakers. Spreads feed game-script reads.

Stack / Stacking. Rostering a group of correlated players from the same team or game to raise your ceiling. Example: rostering several hitters from the top of one strong batting order is a team stack, and pairing it with a hitter from the opposing side is a game stack for a high-total matchup.

Studs-and-Scrubs. A construction style that pairs a few expensive stars with several minimum-salary players, as opposed to a balanced mid-priced build.

T To V

Tilt. The frustration that follows a bad beat, which often leads to undisciplined play. Example: after a chalk play busts, a tilted player chases by jamming more entries than their bankroll should allow. Recognizing tilt and stepping away is bankroll management.

Tournament. A multi-player contest with scaled, top-heavy payouts. Synonymous with GPP in most DFS usage.

Train. Entering the same lineup multiple times into a contest that allows multi-entry. Usually a sign of conviction, though diversifying correlated builds is generally stronger than running one lineup back.

Triple-Up. A contest that pays three times the entry fee to everyone who cashes.

Upside. A player's potential to exceed their projection. Example: "That cheap wing usually does not do much, but at this price the upside makes him a fine tournament dart."

Value. A player whose production should outpace their salary based on matchup, role, or opportunity. Finding value frees up salary to pay up elsewhere.

Vegas Line. The oddsmakers' expected outcome for a game: a favorite, an underdog, a spread, and a combined total. DFS players lean on the total and spread to read game environment.

Viable. A player with a realistic path to a usable, target-reaching score. The bar a play has to clear to make your pool.

A Worked Example: How I Use These DFS Terms On A Slate

Reading definitions is one thing. Here is the order I move through them on a typical NBA night, so you can see how the vocabulary connects. For deeper strategy, our NBA DFS leverage and game theory guide covers the ownership math, the DFS contest selection guide covers picking the room, and the DFS late-swap guide covers the endgame.

1. I open the slate and pull projections and value plays, noting which cheap guys are viable so I know my salary flexibility.
2. I check projected ownership to find the chalk, then look for leverage: lower-owned players close in projection that I can pivot to or fade the chalk for.
3. I decide format. For cash, I want floor and safety. For GPPs, I want ceiling, correlation, and ownership leverage, so I plan my stacks.
4. I build in the Sims, which model the full field and rank lineups by how often they would actually win the contest while I control my exposure across a multi-entry set.
5. Right up to lineup lock, I watch for news and use late swap to react to a ruled-out player or a changed batting order.

That loop, run with real ownership and simulation data instead of gut feel, is the difference between speaking the language and winning with it.

FAQ: Daily Fantasy Sports Terms

What Is The Most Important DFS Term For A Beginner To Learn?

Chalk and ownership, together. In tournaments your score only matters relative to the field, so understanding which players are highly owned (the chalk) and how to leverage off them is the foundation everything else is built on. After that, learn the difference between cash games and GPPs, because they require opposite lineup builds.

What Does It Mean To Fade Or Pivot Off The Chalk?

Fading means rostering a player less than the field does. Pivoting means switching off a popular, high-owned player to a similar-priced, lower-owned one. Both are ways to gain leverage: when your lower-owned choice hits, you jump the large chunk of the field that piled onto the chalk. For example, moving off a 35%-owned guard to a 10%-owned one in the same price tier is a textbook pivot, roughly the same projection with far more upside relative to the field. Stokastic's Ownership Projections show you where the field is concentrating so you can pick your fade and pivot spots.

What Is The Difference Between Cash Games And GPPs In DFS?

Cash games (double-ups, 50/50s, head-to-heads) pay out evenly to a large share of entries, so you want a safe, high-floor lineup that beats about half the field. GPPs are tournaments with top-heavy payouts, so you need a high-ceiling, correlated, differentiated build. A rough rule of thumb: cash rewards the lineup that clears the cash line comfortably, while a large-field GPP usually only pays real money to the top one percent or so, which is why the ceiling matters far more there. Running the same lineup in both is a common beginner mistake, because the optimal build for each is the opposite.

What Is Stacking And Why Does It Matter?

Stacking is rostering correlated players from the same team or game so that when one scores, the others tend to score with them. It is the main way to raise a tournament lineup's ceiling. The Stokastic Top Stacks tool and Sims identify which stacks have the best simulated outcomes and keep your stacked players correlated, for example near each other in an MLB batting order.

Is Daily Fantasy Sports Skill Or Luck?

Both. DFS is high-variance in the short run, so even a strong lineup can finish poorly on a given night. Over a large sample, skill in projections, ownership, leverage, and bankroll management is what produces a positive return. That is why serious players judge themselves on process over results and lean on simulation to weigh a lineup's full range of outcomes, from floor to ceiling, before they lock it in. Daily fantasy is for players 18 and older (19 or 21 in some states) where it is offered, and you should only play with money you can afford to set aside.
