Game modes and modifiers

Room hosts can select a game mode and edit its rules from Room Settings. Rules cannot be changed while a round is in progress.

Standard

Standard matches use the selected stock count, time limit, stage list, and team-attack setting. Rooms can be configured for 1v1, free-for-all, or teams.

Practice

Practice removes the normal stock limit and enables practice commands for testing damage, speed, hitboxes, and other situations. See Practice and CPUs for the available tools.

Modifier

Modifier mode adds optional rules that substantially change a match:

Modifier	Effect
Critical Hits	Enables critical-hit behavior.
Flight	Changes normal movement with a flight effect.
Reverse Angles	Reverses attack launch angles.
Random Angles	Randomizes attack launch angles.
Turbo Mode	Enables faster cancel-based gameplay.
Spontaneous Combustion	Enables the spontaneous-combustion rule.
Ultra Rage	Enables the enhanced rage rule.
Part	Allows Part to appear when Random is selected.

Some modifiers deliberately create unusual or unbalanced matches. Their exact values may change between updates.
