How it works

Solve the 5-digit code by asking questions.

The numbers can be 0 thorugh 9. (0 is even)

Each number can be blue or red. Tap the box to change colors.

Questions cost score points. Asking fewer questions results in higher final score.

There can be repeating numbers in the code. (At most 2 of the same number)

The numbers in the code are always from smallest to largest.
