Secret Number Card Game (1–63)

Think of a number between 1 and 63. For each card, press "Yes" if your number appears on that card. Then press Reveal.

Your secret number will appear here after you press Reveal.

Sum of selected card values: 0

Tip: This is the classic binary trick — each card represents a binary place value (1,2,4,8,16,32). The revealed number is the sum of the smallest numbers shown on cards you answered "Yes" to.
