Event matches (イベント戦 Ibentosen?) are special challenges that were first introduced as a set of 51 single-player tasks in Super Smash Bros. Melee. Each event match puts the player into a scenario with special conditions and a certain objective. The player must complete the objective in order to complete the event match, and the game records the completion and "score" of each event match. A completely new set of 41 single-player event matches was included in Super Smash Bros. Brawl, with a separate set of 21 co-op event matches also included. Brawl also introduced three difficulty levels for each event match - easy, medium and hard.
While most Melee events allow the player to choose any character, with relatively few being pre-determined, this is reversed in Brawl as every event match with the exception of the All-Star Matches and the final two events have set fighters. This appears to be done so that players are forced to use nearly every character at least once, with Luigi and Jigglypuff being the only two characters that do not have to be used in any of the single player event matches. However, this combined with the number and perceived quality of the events makes the mode in general less popular in Brawl than in Melee.
Event Matches in Super Smash Bros. for Wii U function similarly to those in Brawl, but are now arranged on a map instead of a linear list. Completing an event will unlock more events on the map. Additionally, each event will yield a reward if completed under specified conditions, such as playing on a certain difficulty and/or achieving a certain score. Some events also have "hidden routes" that become available if certain requirements are met, such as a character being unlocked. In addition, scores earned will overwrite any inferior scores of lower difficulties; for example, completing an event on normal in 30 seconds will also set the easy difficulty's score to 30 seconds if it is worse or blank. Most events allow the use of customizations, but equipment that has players starting a match with an item will have their extra effect negated; for an example, Beam Sword equipment will not allow the player to start matches with the Beam Sword in any event match. Players can now use different alternate costumes for most character-specific events by picking customized characters who wear them.

In Super Smash Bros. for Wii U, all event matches are unlockable by completing other events, the only exception being the starter events: “The Original Heavyweights”, located in the center of the solo events screen, and “Lurking Menace”, located in the top-left corner of the group events screen. Hidden routes have an additional requirement: players must unlock a specific character (or, in the case of "The Ultimate Battle", all characters) to reveal a hidden route.
