Foldline

A flat net and the solid it is meant to become. Tap a crease and the flap swings up, bringing everything past it along. Card cannot pass through card, so the order you fold in is the whole puzzle. A handful of creases don't say which way they fold — tap for a valley, swipe for a mountain, and printed dice pips or edge tokens are the only clue which is right.

• Tap a crease and the flap swings up
• A fold that would go through a panel is refused
• Valley folds go either way; the printed marks tell you which

80 nets — 68 plus a 12-net valley chapter — a shelf you can spin, and a net of the day.
