How Shiny Odds Work in Pokemon
Shiny Pokemon have alternate color palettes and sparkle when they enter battle. The base odds are 1/8,192 in Gen II through Gen V and were doubled to 1/4,096 starting in Gen VI. Each encounter rolls independently, so hitting the odds on attempt #1 is just as likely as attempt #10,000.
Shiny Charm and Extra Rolls
The Shiny Charm, obtained by completing the Pokedex, adds two extra shiny rolls per encounter in most games. This brings Gen VI+ base odds from 1/4,096 down to roughly 1/1,365. The charm stacks with other methods, making it the single most impactful item for any shiny hunter.
Popular Shiny Hunting Methods
- Masuda Method -- breed two Pokemon from different real-world languages; roughly 1/683 odds in Gen V+
- Chain Fishing -- reel in consecutive hooks without breaking the chain; caps at about 1/96 in Gen VI
- SOS Chaining -- build long chains through SOS calls in Gen VII for up to 13/4,096 odds
- Mass Outbreaks -- Legends Arceus outbreaks offer approximately 1/158 base odds
- Dynamax Adventures -- the best fixed odds in any main game at 1/300 (1/100 with Shiny Charm)
