Shiny Rates Calculator
Estimate your chance to find a shiny based on attempts and odds.
Base shiny odds in Polished Crystal are 1/4096 (same as Gen 6+). The Shiny Charm increases this significantly, making it essential for serious shiny hunters. The Masuda Method (breeding Pokémon from different language games) also boosts odds substantially when combined with the Shiny Charm.
Understanding cumulative probability helps manage expectations: even with 1/512 odds (Masuda + Charm), you're not guaranteed a shiny after 512 eggs - you have about 63% chance. This calculator shows your actual odds based on attempts, helping you decide whether to continue hunting or try a different method. Patience and persistence are key to shiny hunting success.
