Game modifiers (or "mod" for short) are optional modifications to a beatmap's elements and settings that players can enable from the
Mod Selection Screen (above). Mods can make beatmaps easier, harder, or just plain fun.
Players can access the
Mod Selection Screen in the song selection screen by clicking the
Mods button near the lower left corner of the screen or by pressing
F1 on their keyboard. Once in the
Mod Selection Screen, there are also keyboard shortcuts that can be used to select specific mods. These shortcuts may be changed in the Options.
On the selection screen, mods are separated into three categories:
Difficulty Increase, and
Special, and they can either reduce, increase, or remove the
Score Multiplier. When two mods are being used simultaneously, the mods' respective multiplier will be multiplied together (e.g.,
1.06x * 1.12x = 1.1872x).

Each of the mods below listed will have their compatible game modes' icon ( ) next to it.
Note: These mods were used and available some time ago, but are now unavailable.
In tournament matches, NoMod (NM) refers to not using any mods. Many tournaments require some mods to be used by default as part of their rules or format, such as No Fail or ScoreV2, which become exceptions to this notion.
In tournament matches, FreeMod (FM) refers to being free to choose any mod or mod combination. Some tournaments also provide rules that specify additional criteria such as what mods are allowed and in what combinations, or whether having no mods is allowed when FreeMod is specified.
