Each {{OBP|Pokémon|species|species of Pokémon}} has a '''catch rate''' that applies to all its members. Higher catch rates mean that the Pokémon is easier to catch, up to a maximum of 255. When a [[Poké Ball]] is thrown at a wild Pokémon, the game uses that Pokémon's catch rate in a formula to determine the chances of catching that Pokémon.

* Inflicting a status ailment gives the player a flat chance (from 4.6% to 16.6%) to catch the Pokémon regardless of all other factors, making certain Pokémon easier to catch in Generation I than they are in later generations: A sleeping {{p|Mewtwo}} with full HP may, on average, be caught in about six Ultra Balls in Generation I, but from Generation II onwards exactly the same circumstances would require an average of about 64 Ultra | * Inflicting a status ailment gives the player a flat additional chance (from 4.6% to 16.6%) to catch the Pokémon regardless of all other factors, making certain Pokémon easier to catch in Generation I than they are in later generations: A sleeping {{p|Mewtwo}} with full HP may, on average, be caught in about six Ultra Balls in Generation I, but from Generation II onwards exactly the same circumstances would require an average of about 64 Ultra Balls— over ten times as many. | ||
* Due to the nature of the algorithm, Ultra Balls will only perform better than Great Balls on Pokémon whose capture rates are above 55 and below 200 in Generation I.

The formula is slightly different when applied to the [[ | The formula is slightly different when applied to the [[Apricorn]] balls in {{2v2|HeartGold|SoulSilver}}. The modifiers for these balls are applied directly to the Pokémon's catch rate, rather than in the formula. In this case, bonus<sub>ball</sub> is always 1, and the catch rate cannot go higher than 255. This means that for Pokémon whose catch rate is already 255, such as {{p|Rattata}}, the Apricorn balls do not make the capture any more likely than a regular Poké Ball. | ||

Since [[Generation V]], when a Poké Ball is thrown, a special type of capture that is much more likely to catch a Pokémon, called a critical capture, may occur. When a critical capture occurs, the Poké Ball will make a high-pitched whistling sound as it is thrown, then pause in mid-air, and shudder before it drops down to the ground, shaking only once on the ground before the Pokémon escapes or is caught. | Since [[Generation V]], when a Poké Ball is thrown, a special type of capture that is much more likely to catch a Pokémon, called a '''critical capture''' (Japanese: '''捕獲クリティカル''' ''critical capture''), may occur.

The probability of a critical capture occurring depends of the number of Pokémon that have been caught in the Pokédex.
