ESTIMATED RESULT
63.40%With a 1% chance per box, 100 independent boxes give a 63.40% chance of at least one success.
How to use the estimate
Find the target toy's probability in the current game interface, select a mode and enter the values exactly as displayed. The result describes probability across independent attempts; it does not guarantee that a toy will drop by a particular box.
Why a 100% target is unavailable
With any per-box chance below 100%, the probability approaches certainty but never reaches mathematical 100% in a finite number of independent attempts. Use a practical target such as 90%, 95% or 99%.
