Shiny Rates Calculatorin Pokémon Sour Crystal

Estimate your chance to find a shiny based on attempts and odds.

Shiny odds and available bonuses vary by game and method. Use this calculator to see the base rate and any supported bonuses for the game you selected, then enter your attempts to calculate your cumulative chance. A rate such as 1/512 is the chance for each eligible encounter or egg, not a guarantee that a shiny will appear within 512 attempts. Compare methods and attempts here to set realistic expectations for your hunt.

Frequently Asked Questions

What are the base shiny odds in Sour Crystal?
Base shiny odds in Sour Crystal are 1/8,192. The Shiny Charm improves those odds.
Do 1-in-N odds mean I get a shiny in N attempts?
No. Every attempt is independent, so the odds never "reset" in your favour: with flat 1-in-N odds, N attempts still only gives you about a 63% chance of at least one shiny. This calculator shows the real cumulative odds for the number of attempts you enter.
How does the Shiny Charm affect shiny hunting?
The Shiny Charm adds a flat +2 to the numerator over the same 1/8,192 denominator, for wild and breeding encounters. Because the bonuses add rather than multiply, the exact odds depend on your game and method — the calculator applies the values this game actually uses.
