This page sums up 1King's sports betting rules. It covers football, basketball, tennis and esports. Where a specific match has its own rule, that rule appears on the bet slip screen.

General Settlement Principles

These rules form the general framework across every sport. Where a sport-specific rule differs, the sport-specific rule applies.

If a match is delayed by more than 36 hours from its original start time, all bets are voided.
If a match is interrupted and not completed within 12 hours, unsettled bets on markets not yet decided are voided.
If the home and away teams are swapped by mistake, bets are voided — unless the match was played on neutral ground.
In an Over/Under bet, if the total exactly equals the stated line, the bet is voided.
In a Handicap bet, if the result is a draw after the handicap is applied, the bet is voided.

These principles work the same way across every match type. Their purpose is to protect both the player and the platform from unclear situations. When a match finishes under normal conditions, these rules simply don't come into play.

⚽ Football Rules

Football bets are settled on regular time. Regular time means 90 minutes plus time added by the referee. Extra time and penalty shootouts aren't included in the match result bet unless stated otherwise.

Match Result and Over/Under bets settle on the official result of regular time. Goals scored in extra time don't count.
Handicap bets apply the handicap value to the score. If the result is a draw after that, the bet is voided.
In Both Teams to Score, an own goal counts in favour of the opposing team.
To Qualify bets settle including extra time and penalty shootouts.
Card and penalty statistics count only in regular time. A penalty overturned by VAR doesn't count.
Statistical bets (corners, cards, player performance) settle on the official result from an independent sports data source.

Match Result is the most popular football bet type. Handicap and Over/Under bets are also common. Each market's own settlement rule appears on that match's bet slip screen.

🏀 Basketball Rules

Basketball bets are also settled on regular time. If the match ends level, overtime is played and included in the result unless stated otherwise.

Match Result, Quarter Winner and Half Winner bets settle on the official result of regular time. Overtime isn't included.
Winner (Overtime Included) settles including any overtime played.
If the "Mercy Rule" is applied during a match, bets settle on the official result at the moment the rule was applied.
In player statistic bets (points, rebounds, assists and similar), only individual player data counts. Team statistics aren't included.
For a player bet to be valid, that player must have played at least one second in the match.

Over/Under and Handicap bets are especially popular in basketball. Quarter-based bets form a separate category too. In tournament-format matches, to-qualify bets settle on the official results.

🎾 Tennis Rules

Tennis bets remain valid until the match ends. If a player retires or is disqualified mid-match, the following rules apply.

If at least one set has been completed, match result bets remain valid; the winner is decided by the umpire's ruling.
Set bets already settled before the retirement also remain valid.
If retirement happens before the first set is completed, all unsettled bets are voided.
If the match format changes (for example from best-of-3 to best-of-5), bets on unplayed portions are generally voided; bets on completed portions remain valid.
Court surface information is for reference only; bets remain valid even if the surface changes.
If a Championship Tie-Break (a short game played to 10 points) decides a set, that set's game-based bets are treated as settled with a 1-0 score.

Set- and game-based markets stand out in tennis betting. Which bets stay valid after an injury depends on how many games were completed in that set.

🎮 Esports Rules

Esports bets are accepted based on the game's official format. The format is shown as Bo1, Bo2 or Bo3 and stated on the bet slip. If the format changes before the match, bets are voided.

If 4 or more roster players change before the match starts, bets are voided.
If a player disconnects mid-match, the result isn't affected as long as the team continues playing.
The final result is decided by the game's official win condition — for example, destroying the opponent's base or the opposing team forfeiting.
If a forfeit happens before a map is completed, bets not yet settled at that point are voided.
If the match is completed after a technical interruption such as a server crash or network issue, bets remain valid.
In round-based games like Counter-Strike and Valorant, a tied map (e.g. 12-12) goes to an overtime with extra rounds; overtime continues until a winner is decided.
In comparison markets like "Player Duel", if one of the compared players doesn't take part in the match, the related bets are voided.

Esports betting covers popular titles like Dota 2, Counter-Strike, League of Legends and Valorant. Each game has its own win condition and overtime rule. The general principles work similarly across all of them.
