DFS Simulator

Every DFS sport, one simulation engine

DFS Simulator runs Monte Carlo and correlated lineup simulations for 21 sports across DraftKings, FanDuel, and Yahoo — each sport with its own roster shape, scoring system, and correlation structure.

Team sports

Positional rosters under a salary cap, where correlation between teammates — stacks, lines, batting orders — decides tournament equity.

NBA DFS

October – June

National Basketball Association

NBA DFS is a minutes-and-usage game: fantasy scoring tracks possessions, so pace-up matchups, injury-driven usage spikes, and late scratches move projections more than raw talent does. Classic slates roster 8 players under a salary cap, and news in the final hour before lock routinely swings optimal lineups.

NBA lineup simulator

WNBA DFS

May – October

Women's National Basketball Association

WNBA DFS runs on condensed rotations — top players regularly clear 34+ minutes, so usage concentrates in fewer hands than the NBA and ownership piles onto the obvious stars. Slates are small, often 2–4 games, which makes differentiation harder and correlation more important.

WNBA lineup simulator

NFL DFS

September – February

National Football League

NFL DFS is the highest-volume DFS sport: one main slate a week, 9-man rosters with a FLEX, and touchdown variance so large that weekly outcomes are closer to a lottery over one sample than any other sport. Stacking a quarterback with his receivers is the foundational construction because passing production is intrinsically correlated.

NFL lineup simulator

MLB DFS

March – October

Major League Baseball

MLB DFS is the most volatile major DFS sport — even elite hitters fail to reach base in a third of their games — and the most stack-driven, because runs are sequential events shared by adjacent hitters in the batting order. Park factors, handedness splits, and pitcher matchups drive slate-to-slate pricing inefficiencies.

NCAAB DFS

November – April

NCAA Men's Basketball

College basketball DFS offers enormous player pools across hundreds of teams, with slates concentrated around conference play and March. Blowout risk is the defining variable — projected minutes evaporate fast when a 12-point favorite leads by 30 — and pricing is softer than the NBA's.

NCAAB lineup simulator

CFB DFS

August – January

NCAA College Football

College football DFS amplifies everything about NFL DFS: tempo gaps between offenses are wider, scoring distributions are wilder, and a single dual-threat quarterback can post 45+ fantasy points. Saturday slates span dozens of games with pricing that can't keep up with depth-chart churn.

CFB lineup simulator

CFL DFS

June – November

Canadian Football League

CFL DFS plays on three-down football: drives live and die on the pass, receivers see elevated target volume, and the 110-yard field with unlimited pre-snap motion inflates big-play rates. The player pool is compact — nine teams — so slate-level correlation is easy to reason about but hard to differentiate on.

CFL lineup simulator

UFL DFS

March – June

United Football League

UFL DFS is spring football with a condensed player pool and thin public projection coverage — exactly the environment where pricing mistakes persist for weeks. Rosters are small, offensive roles consolidate quickly, and volume is easier to predict than in the NFL.

UFL lineup simulator

EuroLeague DFS

October – May

EuroLeague Basketball

EuroLeague DFS runs on 40-minute games with lower possession counts than the NBA, so totals are compressed and every minute of usage matters more. Star creators shoulder enormous offensive loads, and rotations shift dramatically between domestic league and EuroLeague fixtures.

EuroLeague lineup simulator

NHL DFS

October – June

National Hockey League

NHL DFS is line-stacking chess: goals are shared events between linemates and power-play units, so rostering forwards who skate together doubles the payoff of every goal they combine on. Goalie selection is its own bet — wins and saves versus the risk of an early pull.

NHL lineup simulator

Soccer DFS

Year-round

International Soccer

Soccer DFS scoring splits by position: attackers live on goals and assists, defenders and keepers on clean sheets, which makes same-team defensive stacks and attacking stacks two distinct correlation plays. Slates span leagues and kickoff windows, and a single red card reshapes an entire match's distribution.

Soccer lineup simulator

Field & individual sports

Pick-the-field formats — golf, tennis, motorsport, MMA — where binary outcomes (cuts, wins, finishes, wrecks) make distributions lumpy and averages misleading.

Tennis DFS

January – November

ATP / WTA Tour

Tennis DFS is a pick-the-field format with no team concept: you roster six players from a day's matches, and scoring flows from games, sets, and straight-set bonuses. Win probability dominates everything — a heavy favorite who drops one set still returns most of their projection.

Tennis lineup simulator

Golf DFS

January – November

PGA Tour

Golf DFS rosters six players across four days, and the cut is the format's defining cliff: a golfer who misses the weekend zeroes out half his scoring window. Course fit, recent ball-striking form, and finishing-position bonuses drive pricing more than name recognition.

Golf lineup simulator

NASCAR DFS

February – November

NASCAR Cup Series

NASCAR DFS scores place differential and laps led alongside finishing position, so a fast car starting 30th can outscore the pole-sitter who wins. Dominator points concentrate in one or two cars per race, and wrecks create instant zeros that no projection can smooth over.

NASCAR lineup simulator

F1 DFS

March – December

Formula 1

F1 DFS combines driver and constructor picks where teammate results are mechanically correlated — one team's car is fast or it isn't. Qualifying position sets the baseline, but overtake-friendly circuits and DNF risk decide whether the grid order holds.

F1 lineup simulator

MMA DFS

Year-round

Mixed Martial Arts (UFC)

MMA DFS scores strikes, takedowns, and control time, with large bonuses for finishes — an early knockout or submission routinely doubles a fighter's projection. Every pick is one fight from a zero, and favorites' pricing bakes in win probability but not finishing style.

MMA lineup simulator

Esports

Captain-multiplier rosters where kills are shared events — the winning team's players score together, making correlation the whole game.

League of Legends DFS

Year-round

League of Legends esports

League of Legends DFS rosters players with a 1.5x Captain multiplier, and kill participation makes teammates' scores rise and fall together more than in any traditional sport. Game count matters — a 2-0 sweep caps everyone's ceiling, while a 3-game series inflates it.

League of Legends lineup simulator

Counter-Strike DFS

Year-round

Counter-Strike 2 (CS2)

Counter-Strike DFS scores kills round by round, where star riflers and AWPers concentrate fragging while support players trade value for utility. Map count is the hidden variable — a series that goes three maps adds a full extra game of scoring for every rostered player.

Counter-Strike lineup simulator

Call of Duty DFS

January – June

Call of Duty League

Call of Duty DFS scores kills across modes with very different paces: respawn modes (Hardpoint, Control) produce triple the engagements of Search and Destroy, so a series' mode mix moves projections as much as player skill. Slayer roles out-score objective players in fantasy despite equal in-game impact.

Call of Duty lineup simulator

Dota 2 DFS

Year-round

Dota Pro Circuit

Dota 2 DFS scoring rewards kills, assists, and objective play, and teamfight-driven games push entire winning teams' scores up together. Core players carry kill equity while supports live on assists, so roster construction is a role-weighting problem inside a team-stacking problem.

Dota 2 lineup simulator

Valorant DFS

Year-round

VCT (Valorant Champions Tour)

Valorant DFS scores round-based kills where duelists absorb the fragging role and controllers trade kills for map control. Like CS, series length is the ceiling multiplier, and star players' opening-duel win rates drive round-level scoring runs.
