 * Starter stages were Battlefield, Final Destination, Dream Land, Fountain of Dreams, and Yoshi's Story. Unconventional stage striking was used (one player strikes 2 stages, then the other player strikes 2 stages).
 * Counterpick stages were Pokémon Stadium. Dave's Stupid Rule was used, but there were no counterpick stage bans.
 * Wobbling was banned.
 * Air time rule: If a game times out with tied stocks, and one player's air time was 80 seconds longer than the other's, that player loses. If the difference is less than 80 seconds, whoever had less damage wins.
 * If a game times out with stocks and percent both tied, and the air time difference is less than 80 seconds, the higher port number wins.
 * If a game ties due to both players losing their last stock on the same frame, a 1-stock 2-minute rematch on the same stage is played.
 * The ruleset also explicitly stated that Deflicker must be turned on and that Sound must be set to mono.
 * From November 2014 onward, the following changes were made:
 * Stage striking was changed to the conventional 1-2-2-1 order.

 * Up to SumabatoX 9, the following end-of-game rules applied:
 * If Sudden Death occurs, it is played out with a ledge grab limit of 1 (grabbing the ledge twice is counted as losing Sudden Death).
 * If a game times out (whether there was a stock lead or not) or if Sudden Death was played (whether the game timed out or not), there is a ledge grab limit of 60 used afterward.
 * If a player grabbed the ledge 61 or more times, that player loses. If both players grabbed the ledge 61 or more times, whoever grabbed the ledge more often loses. These conditions override a time out stock lead or a Sudden Death result. Any ledge grabs performed during Sudden Death do not count toward the 60.
 * From SumabatoX 15 onward, the following end-of-game rules applied (any changes between and  have been lost):
 * The ledge grab limit is lowered to 40. If a game times out and only one player has broken the ledge grab limit (has grabbed the ledge 41 or more times), that player loses regardless of tied stocks or stock lead.
 * If a game times out with a stock lead, and neither player or both players have broken the ledge grab limit, whoever has the stock lead wins.
 * If a game times out and stocks are tied, and neither player or both players have broken the ledge grab limit, whoever's sum of (damage % + ledge grab count) is lower wins.
 * If both players lose their last stock on the same frame, Sudden Death is played out with a ledge grab limit of 1. Sudden Death is not played out in any other case.
 * 'Round-trip scrooging' is banned.
 * A player may travel under the stage once (counted when the player reaches the height of the opposite ledge), but then must either inflict damage, take damage, or land on stage (Smashville's moving platform does not count) before being allowed to travel under the stage in the opposite direction.
 * Infinite combos cannot be performed past 350%. Infinites that do no damage cannot be continued for more than 3 seconds.
