Grand Blue reroll calculator
Rerolls feel cheap one at a time and expensive in aggregate. Check the math before you burn them.
Reroll calculator
Enter a reroll's success chance and how many rerolls you can afford, and see your real odds before you spend.
Why odds feel worse than they are
A 0.5% chance does not mean one success per 200 rerolls — it means a coin-flip after about 138 rolls and real confidence only past 460. The calculator converts your stack of rerolls into the number that actually matters: the chance you walk away with the result you wanted.
Free rerolls add up fast. Codes currently in rotation pay out roughly 140 Trait Rerolls and 50 Race Rerolls combined — redeem them all before you judge your luck.
