❗Sports Trading Guidelines
Overtime is a decentralized, trustless, permissionless, blockchain based sportsbook. Overtime’s novel Sports Automated Market Maker is built on Overtime smart contracts, and it uses reliable data feeds from the industry best data provider Chainlink.
The smart contract architecture ensures a safe, transparent and reliable way of trading with the Sports AMM. Every trade is fully collateralized, and the funds will always be in respective smart contracts, waiting for you to claim if your trades were correct. The smart contracts themselves are the first and foremost source or truth. Code truly is law with Overtime.
Changes to the contract codebase of Overtime can only be done as a result of a OIP (Overtime Improvement Proposal) being voted in by the Overtime Council, the elected governing body of the Overtime DAO, consisting of reputable Overtime community members. Overtime DAO also governs all the markets and transactions of the protocol.
Listed below are the Overtime trading rules and guidelines to offer a standardized and familiar way of interacting with the Overtime platform:
Table of Contents
General Rules
Overtime Markets – Universal General Rules
Oracle & Governance Pipeline Data comes from Chainlink nodes and pre-approved providers; any change to feeds or contract logic must pass a OIP vote of the Overtime DAO Council.
Market Types & Outcomes Overtime supports 2-way and 3-way markets (excluding Futures markets like Golf, F1 or similar). For 2-way sports, overtime/extra-time scores are included by default; for 3-way sports, only regulation counts unless noted.
Draws & Pushes (2-Way) If a “Draw” price is listed and the match ends in a draw, both team selections lose. Where no draw option exists and the match ends in a draw, bets are void.
Walkovers / No-Contests Any forfeit, walkover, or “no contest” voids all bets on the fixture(some exceptions may apply )
Abandonment Threshold If a fixture is not completed within 24 hours of its scheduled start, all full-game markets are void (periods already finished stand). Exceptions: events naturally exceeding 30 h (e.g., multi-day golf).
Start-Time Windows A fixture that fails to begin within 24 hours of the advertised start time is voided in full.
Long-Duration Events Tournaments that normally run past 30 hours (major golf, multi-round motorsport, etc.) retain action provided they finish under the organiser’s published schedule.
First-Score Markets “First Team/Player to Score” have action as soon as the score occurs—match completion not required.
Venue / Opponent Changes Unless a sport-specific rule overrides, swap of the listed opponent voids all bets.
Period-Only Bets Bets designated for a specific quarter/period count only that segment; completed periods stand even if the match is later abandoned.
Participant-Must-Start Rules If a market contains named competitors (e.g., Head-to-Head, Player Props), all listed competitors must start or bets since the last completed stage are void.
Minor Data Entry Errors Typos, misspellings, or team name variations do not void action when the intended fixture is clear.
Non-Standard Match Formats If a fixture is mistakenly offered with the wrong number or length of periods, every market on that fixture is void.
Parlay Specials/ SGPs Parlay Specials or SGPs require all listed games to finish; otherwise the entire special is void.
Integrity & Material-Error Handling Overtime may suspend markets, reject, or later void trades if fraudulent activity or an obvious pricing/limit error is detected, including post-acceptance in-play bets that gained a material advantage.
Live Scoreboard Disclaimer In-game scoreboards are informational only; incorrect live data shown there does not constitute grounds to void a bet. The result after grading is the one that counts.
Bet Acceptance & In-Play Delays All wagers are accepted at Overtime’s discretion; in-play orders may queue briefly or pend during high-risk moments. Obvious odds errors may be cancelled.
Official Result Source Unless a sport rule states otherwise, the governing body’s determination at fixture completion is final; protested or later-overturned scores are not recognised.
Rule Precedence Chain Market-specific rules override Sport rules, which override these General rules if a conflict exists.
DAO Dispute Resolution Users may escalate irregularities to the Overtime DAO in the Overtime discord
These General Rules apply across every sport section that follows in the GitBook documentation and are crafted to dovetail with the existing Overtime Sports-Trading Guidelines.
Sports Rules
American Football 🏈
Timing & Suspension
Overtime counts for all Game and 2nd‑Half markets, unless explicitly stated otherwise.
Market‑Specific Rules
Team to Score Next: Only Touchdowns, Field Goals and Safeties qualify. PATs and 2‑Point Tries are treated as part of the prior Touchdown.
Player props have action only if the player records at least one snap (offense/defense/special teams)
Passing Yards / Passing TDs: Listed QB must attempt ≥ 1 pass for action; otherwise bets void.
Rushing Yards: If the named player records no rushing attempt, yardage is 0.
Receiving Yards / TDs: If the named receiver plays but makes no catch, yardage/TDs settle at 0.
Anytime Touchdown Scorer: Player must possess the ball in the end‑zone. Passing for a TD does not count for the QB.
Longest Touchdown: Market void if no Touchdown is scored.
Special‑Teams & Defensive TD: Only plays that involve a kick/punt or a post‑snap change of possession (e.g., KO return, INT return, blocked‑kick return) qualify. Fake FG/Punt TDs grade as Offensive TDs.
Unanswered Scores: Ignore PATs/2‑Point tries and any defensive return on those plays.
Season & Futures
Regular‑Season Win Totals: Settle once a team’s result is mathematically locked over a 17‑game (NFL) or 12‑game (NCAAF) slate. League‑declared forfeits count as played games.
Conference / Division / Championship Futures: Graded on the team that reaches the official title game (e.g., Super Bowl, CFP Championship).
Soccer ⚽️
Core Timing Rules
Regulation‑time settlement. All match markets are graded on the score after the scheduled 90 minutes plus any referee‑added stoppage time. Extra‑time, golden‑goal periods and penalty shoot‑outs never count unless a market title explicitly states “Incl. ET”.
Venue & Home/Away Status
Bets stand at neutral venues regardless of listing order. If the governing body designates a team as “home”, that team is treated as home for all Home/Away splits even if the game is staged at the opponent’s ground.
In‑Play Integrity
VAR adjustments. In‑play bets struck between the on‑field incident and the VAR overturn are void if the reversal materially alters odds.
Displayed data errors. If the score, corner count or red‑card state shown in the market header/Bet‑Slip is wrong, any bets placed while the error persists are void. Third‑party live scoreboards outside the bet UI are informational only.
Event‑Timing Scope
Unless a market specifies a minute range, referee‑added injury time is included in that market’s period.
Specific Market Rules
To Advance / To Lift Cup: Settled on the team that progresses, regardless of venue changes, postponements or method of victory (ET/penalties).
Season Points & League Winner/Relegation: Settled on official league table. Season point totals lock once mathematically decided and are not reopened if the league later shortens its schedule.9.
Home vs Away Totals: If played at a non‑standard venue, the team listed first is treated as home unless the governing body states otherwise.
Corners: Retaken corner counts once. Awarded but untaken corners do not count.
Next Goal / Race to X Goals: Graded immediately once outcome occurs, regardless of subsequent abandonment.
Player Must Start: All pre‑match player props void if the named player does not start. Substitute appearances do not trigger action.
Anytime Goalscorer: Only goals in regulation/stoppage count; own goals excluded. Extra‑time & penalty shoot‑out goals excluded.
Tournament Player Props: Stats from extra‑time count; penalty shoot‑out events do not.
Shots on Target (SOT): Excludes blocked shots. Only goals and attempts that would have entered the goal but for a goalkeeper save (or provider‑classified equivalent) are counted as SOT. Deflections off outfield defenders that stop the ball before reaching the goal do not count as SOT.
Basketball 🏀
Timing & Suspension
Overtime – Counts for all Game and 2nd‑Half markets, as well as player props, unless a market title states “regulation only”. OT never counts for 1st‑Half or individual Quarter markets unless explicitly indicated.
3‑on‑3 Basketball (FIBA 3×3 & BIG3)
Game is official when 10 minutes plus any OT are completed or a team reaches 21 points, whichever comes first. If neither condition is met, all wagers are void.
Market‑Specific Rules
Conference Winner (NBA) – Winner is the franchise that reaches the NBA Finals, independent of subsequent Finals outcome.
Player‑stat markets (pre‑game & live) with one or more named players – All listed players must enter the game for action, unless the market wording states otherwise.
Double/Triple‑Double – Double‑double = ≥ 10 in any two of PTS/REB/AST/STL/BLK; Triple‑double = ≥ 10 in any three of those stats.
NBA Player Stats – Settlement Timing: All NBA player stat markets are settled shortly after the game ends, using the official box score available at that time. We do not wait for end-of-day stat corrections or league adjustments — only the values at the conclusion of the game are used. Once settled, results are final.
Baseball ⚾️
Game Completion & Action Thresholds
Pre‑game Moneyline action: Official once 5 full innings are completed († 4½ if the listed Home team is ahead).
All other full‑game markets (run‑line, totals, team totals, H+R+E, player props, etc.) require 9 full innings († 8½ if Home team leads) unless explicitly titled “7‑inning game”.
If the contest is called early, score reverts to the last completed inning—except if the game is called in the bottom half and the Home side has taken the lead, in which case the current score stands.
Periods (5‑inning, 1st Inning, etc.) that have concluded stand regardless of later abandonment.
Suspensions & Resumptions

Double‑Header (7‑Inning) Fixtures
Market titles must state “7 Inn”. If mis‑labelled, all wagers void.
Moneyline official after 5 IP (4½ if Home ahead). All other full‑game markets require 7 IP (6½ if Home ahead).
Rule‑book Mercy invokes completion for settlement purposes.
Pitcher & Line‑up Definitions
A starting pitcher is deemed to have started once they throw their first pitch. A non‑pitcher is deemed a starter once they make their first plate appearance (or take the field defensively for league‑designated “Opener” formats).
Where a market lists one or two named competitors, all must start for action, except “Save” props which have action regardless of relief appearance.
Overtime does not void markets based on listed starting pitchers; odds stand even if rotations change.
1st Half (5‑Inning) Markets
Pre‑game 1H Moneyline/Run‑Line official after 5 IP (4½ if Home ahead & game called). In‑play 1H wagers require full 5 IP.
Market‑Specific Notes
Total Bases: Single = 1, Double = 2, Triple = 3, HR = 4. Walks, reach‑on‑error, HBP do not count.
Hits+Runs+Errors: Game must reach full‑game action threshold; if called in extras, revert to last completed inning unless Home scores to tie or win in bottom half.
Ice Hockey 🏒
Core Timing Rules
NHL All‑Star & exhibition formats: Listed markets have action regardless of minutes played or period count.
Overtime & Shoot‑out Treatment
Overtime (OT) and any penalty shoot‑out (SO) are considered the same period for settlement.
Game‑period lines labelled “Incl. OT/SO”: Shoot‑out winner is awarded one (1) goal for grading purposes.
Regulation‑only (3‑way) lines exclude OT/SO entirely.
Period and 60‑minute exact‑score markets always exclude OT/SO.

NHL Player Stats – Settlement Timing: All NHL player stat markets are settled shortly after the game ends, based on the official box score available at that time. We do not wait for late stat corrections or league adjustments — only the values at the conclusion of the game are used. Once settled, results are final and will not be updated based on any subsequent NHL revisions.
Season & Futures
Conference Winner (NHL): Team that participates in the Stanley Cup Final.
Tennis 🎾
Match Integrity & Time Limits
Player Forfeits – Match Rules: If a match has started and a player forfeits, the opposing player will be deemed the winner for settlement purposes. Totals and spread markets will be canceled unless the outcome was already mathematically determined at the time of the forfeit.
All other markets (Set Handicap, Game Totals, etc.) are void unless the quoted segment was already settled before the retirement/disqualification.
Venue / Surface changes (indoor ↔ outdoor, hard ↔ clay/grass) do not void bets.
Scoring Conventions
Any tie‑break or match tie‑break counts as one game for Game‑Totals and Handicaps. ITF singles (non‑Grand‑Slam) & all doubles where a match‑deciding super tie‑break is used:
Live markets and pre‑match Money‑Line have action; however, pre‑match Spread & Total markets are void because the final‑set game count is indeterminate.
Pro‑Set formats (first to 8/10 games): Only 1st‑Set ML, 2nd‑Set ML (if scheduled) and Match ML are actionable; all other bets void.
Unless stated otherwise, Handicap and Total lines use games won as the unit.
In‑Play Specifics
The next point must be played for any in‑play wager to stand. If a player retires or is defaulted before the subsequent point starts, all bets placed since the last completed point are void.
Futures & Outrights
All outright bets have action regardless of draw re‑seeding or venue shift, unless the market text specifies that certain named players must start.
Esports 🎮
Universal Rules
Start‑time window – If a match is not underway within 24 hours of its advertised start, all bets on that match are void.
Format integrity – Material changes to the match format (best‑of length, map pool, round limit) void all wagers unless the market explicitly accommodates the new format or the change cannot affect the outcome of that market.
Default map advantage – Admin‑awarded advantages (upper‑bracket “auto‑map”) are incorporated into Match lines. Walkovers before play do not count toward map totals.
Overtime / Tie‑breaks – All overtime or tie‑breaker rounds count toward markets unless the market title states “Regulation Only”.
Roster minimum – Any map that begins with fewer than the official team size (typically 5‑v‑5 or 10 total competitors) is void.
Map forfeit - If a map is not played all the way and is forfeited, the bets on that maps will be voided unless the outcome of the market has already been mathematically determined (for example Player Kills Over line is covered)
CS 2
Map is void if played with fewer than 10 competitors for 4 rounds or if a team retires / receives an admin win before the map’s scheduled rounds complete.
Rounds 1‑12 constitute the first half.
A Match Medic rewind grades markets from the reset round; any stat‑dependent markets invalidated by the rewind are void.
If any map switches to CS:GO (MR 15) mid‑series, all match/map markets impacted by the format swap are void.
Valorant
Same roster and 4‑round early‑void logic as CS 2.
Rounds 1‑12 constitute the first half.
Match Medic restarts follow identical grading rules.
Dota 2
Disconnect/admin win within first 10 minutes → map void; after 10:00 → bets settle on official result.

League of Legends (includes Wild Rift & Mobile Legends variants)
Same 10‑player start rule and 10‑minute disconnect/admin‑win threshold as Dota 2.

Map void if a team retires, receives an admin win, or is disqualified before completing all scheduled rounds.
