====Generation IV====
====Generation IV====
In Generation IV, there is now a 5/8192 (~1/1639) chance of hatching a [[Shiny Pokémon]] when the parents have different original languages, a five times increase of the usual rate. This mechanic is known as the [[Masuda method]], after [[Junichi Masuda]].
Starting in Generation IV, if the two parents have different [[language of origin|languages of origin]], the Pokémon in Eggs they produce are more likely to be Shiny due to the [[Masuda method]]. The game does this by generating up to four additional personality values if the Pokémon is not Shiny, meaning that the Pokémon is approximately five times as likely to be Shiny (approximately 5/8192 or 1/1639).


====Generation V====
====Generation V====
Starting in Generation V, the [[Masuda method]]'s success rate increased from 5/8192 (~1/1639) to 6/8192 (~1/1366).
Starting in Generation V, the [[Masuda method]] now generates five additional personality values, meaning that the Pokémon is approximately six times as likely to be Shiny (approximately 6/8192 or 1/1366).


In {{game|Black and White|s|Pokémon Black 2 and White 2|2}}, the [[Shiny Charm]] was introduced, which if owned by the player will increase the chance of encountering or hatching a Shiny Pokémon by a flat 2/8192, to 3/8192 (~1/2731) for a regularly bred Pokémon, or 8/8192 (1/1024) if the parents have different original languages.
In {{game|Black and White|s|Pokémon Black 2 and White 2|2}}, the [[Shiny Charm]] was introduced, which increases the player's chance of encountering or hatching Shiny Pokémon while in the player's Bag. If the player has the Shiny Charm when an Egg is generated, the game generates two additional personality values if the Pokémon is not Shiny, meaning that the Pokémon is approximately three times as likely to be Shiny (approximately 3/8192 or 1/2731).
 
The Shiny Charm and Masuda method can both apply at the same time. If they both do, their rerolls stack, resulting in seven additional personality values being generated, meaning that the Pokémon is approximately eight times as likely to be Shiny (approximately 8/8192 or 1/1024).


====Generation VI====
====Generation VI====
In Generation VI, the Masuda method's success rate when combined with the [[Shiny Charm]] is increased to 1/512 odds.
The overall Shiny rate has been increased to 1/4096. As a result, while the number of rerolls remain the same, the probability of hatching a Shiny Pokémon when using the Masuda method or Shiny Charm has also increased.
* The Masuda method alone generates five additional personality values (approximately 6/4096 or 1/683 chance of a Shiny Pokémon).
* The Shiny Charm alone generates two additional personality values (approximately 3/4096 or 1/1365 chance of a Shiny Pokémon).
* The Masuda method and Shiny Charm together generate up to seven additional personality values (approximately 8/4096 or 1/512 chance of a Shiny Pokémon).


====Generation VIII====
====Generation VIII====
In Generation VIII, the Masuda method's success rate when combined with the [[Shiny Charm]] remains 1/512 odds, however due to the "off-by-one" bug<ref>https://twitter.com/SciresM/status/1319805906691842050?s=20</ref>, a bonus roll is lost if there is more than one shiny roll. This causes the Shiny Charm to grant only 2 total rolls (1/2048 odds) instead of +2 when used alone, and Masuda method to grant only 6 rolls (1/683 odds) instead of +6 when used alone. When used together, this still results in the combined total of 8 rolls. (1/512 odds)<ref>https://twitter.com/SciresM/status/1319799153162006530</ref>
In Generation VIII, the Masuda method now generates six additional personality values, which would make it more likely to hatch a Shiny Pokémon. However, due to a bug, the original roll is skipped if any bonus rolls are applied while breeding, resulting in the Shiny chance while using the Masuda method unchanged, but lowering the chance when using the Shiny Charm without the Masuda method.<ref>https://twitter.com/SciresM/status/1319799153162006530</ref><ref>https://twitter.com/SciresM/status/1319805906691842050</ref>
* The Masuda method alone generates a total of six personality values (approximately 6/4096 or 1/683 chance of a Shiny Pokémon).
* The Shiny Charm alone generates a total of two personality values (approximately 2/4096 or 1/2048 chance of a Shiny Pokémon).
* The Masuda method and Shiny Charm together generate a total of eight personality values (approximately 8/4096 or 1/512 chance of a Shiny Pokémon).
