Pokemon Ultra Sun & Ultra Moon Shiny Odds

Pokemon Ultra Sun and Ultra Moon keep SOS chaining and add Ultra Wormhole hunting, where distance and ring color raise your odds. Compare every method against the Shiny Charm here.

Shiny Odds Calculator

Every shiny check is an independent roll, so your per-encounter odds never move no matter how long you've hunted. What climbs is your cumulative chance, the odds you'd have found one by now, and that's the curve the ring below tracks.

Shiny Locked Pokemon

Shiny-Locked Pokemon in Ultra Sun & Ultra Moon

Nine Pokemon are locked, but every past-gen legendary behind a wormhole is fair game.

Shiny Mechanics and Quirks

Ultra Sun & Ultra Moon Shiny Mechanics and Quirks

Two systems define Alola hunting: wormhole distance and SOS chains.
WORMHOLEDistance is everything
Wild spawns inside Ultra Space scale with light-years travelled and ring rarity, up to a 36% shiny rate at the longest distances in the rarest rings. The legendaries themselves stay full odds, but they are soft-resettable statics.
CHAINSOS caps at 31
Ally chains add shiny rolls in tiers at 11, 21 and 31, then stop. Past 31 there is no further gain: hold the chain at cap, manage the caller's PP, and let the odds do the rest.
PREPAdrenaline Orbs are cheap
One Orb per battle doubles call rate for the whole fight; a second use just wastes the turn. False Swipe keeps the caller alive and calling all chain long.
