Competitive play may be either singles, or doubles. In singles, two players face off against each other. In doubles, two teams of two players fight each other. Sharing stocks with teammates is allowed. Friendly fire is enabled, so teammates can damage or save each other. This is to ensure fairness, as certain combinations of characters in teams can prove to be overpowered. It also ensures that two-on-one situations aren't overwhelmingly tilted in the winning team's favor. It also adds a couple of extra strategies. For example, some characters can absorb attacks, to heal themselves or to charge an attack for later use. With friendly fire on, a player can attack their ally specifically to allow them to absorb it. Additionally, most characters have a triple jump that, once used, prevents the character from taking any action until they are hit with an attack, land back on the stage, are KO'd. If a player is not going to make it back to the stage, their ally can hit them with a weak attack, allowing them to re-use their triple jump and make it back. A similar thing applies to Jigglypuff's Rest move, which is extremely powerful, but immobilizes Jigglypuff for several seconds, unless it is hit by an attack. An ally can use his or her weakest move to knock Jigglypuff out of this state, denying the enemy the chance to use a powerful move on it. "Super Smash Bros. for Wii U" adds an 8-player mode, which allows triples and quadruples teams, although there have been comparatively few tournaments.
