How to Play
- Watch the folds
The dashed line is the crease, the arrow is the direction.
- Note the punch
The hole goes through every layer underneath it.
- Open it out
Pick the sheet that the folds and the punch would actually make.
Fast Fold
Fold the paper, punch a hole through the folded packet, open it out. How many holes are there, and where?
Ready to unfold it in your head?
One, two or three folds, then a punch. Four sheets to choose from and only one of them is what you would actually get.
Each fold doubles the holes. A hole on the crease itself does not.
What It Challenges
- Mental rotation
Turn and flip a shape without turning anything on screen.
- Spatial working memory
Hold each fold while you apply the next one.
- Sequential reasoning
Undo a series of steps in the right order.
