How to play

Imagine a square of paper. The puzzle folds it in half one or more times, then punches a single hole through all the stacked layers. When you unfold the paper flat again, each layer has a hole — but in a mirrored position.

1Read the fold diagrams above the grid. A vertical fold mirrors everything left↔right. A horizontal fold mirrors top↔bottom. 2Look at the punch position in the final folded state, then mentally unfold one step at a time, mirroring the hole across each fold. 3Click cells on the grid to mark every spot you think will have a hole. Click again to unmark. 4Hit Check Answer. Green = correct, red = you missed it, pink × = you marked a spot with no hole.

Tip: with N folds you'll usually see 2^N holes — fewer only if the punch sits exactly on a fold line.

Watch the folds, then predict the holes.
