Liar's Count

Count the clicks. Count the question marks. The number lies.

The Rule

Tap the block. Keep tapping — at some point it disappears, and that ends the round.
Count every tap you make. The number printed on the block starts honest and then begins to lie.
Sometimes it prints ? instead of a number. Count those separately.
When the block is gone, hand in both numbers: total taps, and how many question marks you saw.

Tap it

It disappears on its own. No warning.
