Slateline is an educational research and analysis product. It does not place bets or accept wagers. Projections are estimates, not guarantees. If gambling stops being fun, call 1-800-GAMBLER.

Player prop intelligence that starts with the projection

Sports & models

Twelve projection engines (9 live), one accountability standard: full distributions, versioned models, graded results, and honest labels on the state of the data. Live sports publish boards, and built engines open with their seasons or data feeds.

MLBLive

sim-mc-2.2 · Plate appearance simulation (~4,000 full simulations per game)

Projects hitter and pitcher props from thousands of full game simulations of every game on the slate, priced against live DFS lines and a sportsbook consensus. Live and graded nightly.

Data status

Live DFS lines plus a sportsbook reference with the vig removed. Verified markets grade against final official statistics. New pitch and workload markets are provisional research inventory, and unverified settlement stays pending.

WNBALive

wnba-sim-0.3 · Possession level simulation with minutes and availability per simulation

Projects points, rebounds, assists, and combo props from possession level simulations built on minutes and availability. Live on real lines and graded nightly.

Data status

Live lines from four DFS books, priced on player rates measured from recent box scores, graded nightly. Injury statuses default to healthy until a licensed feed is connected, and affected projections are flagged.

NBAOpens late October

nba-sim-0.4 · Possession level simulation, 240 team minutes conserved

Projects scoring, rebounding, and playmaking props with rest days, load management, and blowout minutes built into every simulation. Ready for opening night in late October.

Data status

The engine is built and has passed two audits. Live player rates and DFS lines connect when the season opens in late October.

NFLLive

nfl-sim-0.4 · Drive level simulation aware of the game script

Projects passing, rushing, and receiving props from drive by drive simulations that follow the flow of the game. Live on real lines for the season.

Data status

Real DFS lines priced against measured NFL data: player usage and efficiency from nflverse (community play by play and weekly stats, CC BY 4.0, used with attribution), team profiles anchored to the measured league, and kickoff weather from the National Weather Service. Injury designations enter from the roster file and, when the licensed feed is configured, from RotoWire. The board states which. No sportsbook posts two sided prices on these markets, so edges read model versus line, and every grade is capped at B+ until the backtest earns more. Graded weekly from official box scores.

College FootballLive

ncaaf-sim-0.2 · Drive level simulation on the audited NFL chassis plus college mechanics

Projects college football props with the sport's own realities simulated: early starter pulls, backup snaps, and wide differences in team tempo. Live on real lines for the season.

Data status

Real DFS lines priced against measured college data: player usage and efficiency from last season's play, opponent adjusted team ratings, returning production, and transfer moves. Rosters are current, player availability has no live feed yet, and every player builds healthy, stated on the board. No sportsbook posts these markets, so edges read model versus line, and every grade is capped at B+ until the backtest earns more. Graded volume is still thin (1,371 settled rows) and the probabilities run overconfident at the extremes, so treat them as directional until the calibration curve tightens.

College BasketballOpens early November

ncaab-sim-0.2 · Possession level simulation with college game structure (two halves, bonus FTs, five fouls, end game fouling)

Projects college basketball props around the college game's own rules: five fouls, bonus free throws, and deliberate late game fouling. Ready for the November season.

Data status

The engine is built and audited, and simulates college structure directly: five fouls, the bonus free throw ramp, end game fouling, two foul benching, and rosters heavy with transfers. Live stats and lines connect with the November season, and every grade is capped at B+ until the backtest earns more.

Engine built and audited · Opens early November
TennisLive

tennis-sim-0.2 · Point level simulation through the real scoring tree

Plays out every service game, tiebreak, and set to project aces, games won, and match length for ATP and WTA players. Live on real lines all year.

Data status

Live DFS lines priced on serve and return rates measured from each player's recent matches, split by surface. No sportsbook posts tennis player props, so edges read model versus line, and every grade is capped at B+ until the backtest earns more.

GolfWaiting on data

golf-sim-0.2 · Hole level simulation (fairway → green → outcome → putts chain)

Projects birdies, strokes, and cut chances hole by hole, with PGA cut weeks and LIV's 54 hole events treated as genuinely different formats. Built and audited, waiting on a strokes gained data feed.

Data status

The engine is built, verified by harness, and adversarially audited, with PGA cut events and LIV 54 hole shotgun events as separate formats. DFS golf lines are confirmed available. The missing piece is a licensed strokes gained data feed, not the calendar.

UFC / MMALive

mma-sim-0.3 · Tick level fight simulation (striking, clinch and ground states, 30 second segments)

Projects significant strikes, takedowns, and fight time from moment by moment fight simulations where an early finish settles the number instead of voiding it. Live on real lines for UFC cards.

Data status

Real DFS lines priced against measured fighter statistics. Full cards build on fight days, and every published prop grades against final fight statistics the morning after. No sportsbook posts these markets in usable form across books, so edges read model versus line, and every grade is capped at B+ until the backtest earns more.

SoccerLive

soccer-sim-0.2 · Match level simulation (possession environment, allocation by share slot, realized substitution windows)

Projects shots, passes, tackles, and saves with lineups and substitution timing simulated first, because minutes decide everything. Live on real lines for World Cup and club matches.

Data status

Real DFS lines priced against measured team and player inputs: posted lineups with a status of confirmed or projected, match statistics per player, and substitution timing from recent matches. An unposted lineup caps every grade for that match. No sportsbook posts soccer player props in usable form across books, so edges read model versus line, and every grade is capped at B+ until the backtest earns more.

League of LegendsLive

lol-sim-0.3 · Simulation of a series of maps on a per minute game clock

Projects kills, assists, and creep score map by map, with game length driving every number and series sweeps priced in. Live on real lines for pro league matches.

Data status

Real DFS lines priced against measured pro match data: league pace, team styles, rosters, and role shares, using only games played before each series. Projections are made before champion select, so distributions widen to carry that uncertainty. No sportsbook posts these markets, so edges read model versus line, and every grade is capped at B+ until the backtest earns more.

Counter-Strike 2Live

cs2-sim-0.3 · Simulation of a series of maps at round level (MR12 score race, overtime blocks)

Projects kills and headshots round by round, where close maps run long and lift both teams' totals. Live on real lines for pro matches.

Data status

Real DFS lines priced against measured match data: kill and headshot shares per player, team strength, and map pools from recent finished maps. Before the map veto, projections mix the likely map pool and say so, and a stand in or unconfirmed roster caps the grade. No sportsbook posts these markets, so edges read model versus line, and every grade is capped at B+ until the backtest earns more.
