'''Accuracy''' (Japanese: '''めいちゅう''' ''accuracy'') is property of [[move]]s that, in conjunction with the user's in-battle {{stat|accuracy}} stat and the target's {{stat|evasion}} stat, determines how likely a move is to hit.

Moves always a miss a Pokémon that is in the semi-invulnerable turn of {{m|Fly}} or {{m|Dig}}, except {{cat|moves that cannot miss}}. In the Japanese version of the Generation I handheld games, due to a bug, even moves that cannot miss will miss when used against a Pokémon that is in the semi-invulnerable turn of a move, unless that target is behind a substitute.

* ''Accuracy<sub>move</sub>'' is the move's accuracy, a value from 1 to 100 (internally, 0 is also a valid value, but this is displayed as "&mdash;" and means that the move ignores accuracy checks),

* ''Adjusted_stages'' is the equivalent accuracy [[#Stage multipliers|stage multiplier]] of the user after the target's evasion stage is subtracted from the user's accuracy stage, both possibly modified by Ability or move effects such as {{a|Simple}} or {{m|Foresight}} (to no less than -6 and no more than 6 after the subtraction), and

The game then selects a random number ''R'' from 1 to 100 and compares it to ''A'' to determine whether the move hits. If ''R'' is less than or equal to ''A'', the move hits.
