The Rules is an option in the Super Smash Bros. games. It lets players select the rules for a match before the fight itself.
- Rules Selects the type of match.
- Time (pick the Time limit of the match, once the time limit runs out, the match end and the person or team with the most KO's wins)
- Stock (set amount of lives, the last person or team standing with at least one life wins, or person with most lives at Time)
- Coin (set time limit, once the time limit runs out, the person or team with the most smash coins wins)
- Bonus (Melee only, set time limit, when time ends, player with most points from bonuses wins)
- Handicap SSB and Melee: Changes knockback given and received, from 1 to 9.
Brawl: Sets damage percentage at the beginning of the match, from 0% to 300%. Even if characters lose a stock, they return with the handicap back at what it was at the start of the match.
Can be set to:
- Auto, which determines the individual handicap of each player by previous wins and losses
- Damage Ratio sets how much knockback is received from attacks. The default ratio is 1.0. The higher the number, the further the player will be launched. Players can choose the ratio from .5 to 2.0., increments of .1.
- Stage Choice Allows the player to adjust on how the stage will be decided:
- Choose - Allow freely to pick any stage
- Random - Stage choice will be picked randomly
- Turns - Take turns start with Player 1, then Player 2 and so on
- Ordered - Play Stages in order
- Loser's Pick - The loser of the match gets to decide to pick the next stage
- Items Allows what items can be in the match or not and adjusts how often an item will appear. The player can set how often an item appears by picking the choices: None, Low, Medium, or High. Melee also includes the choices of "Very Low" and "Very High".
