Foldwork Daily

Foldwork Daily gives you a flat sheet and a target shape, and you fold it into place one crease at a time. Early puzzles are a warm-up; by the third week I was staring at my phone on the balcony trying to reverse-engineer a fold I'd made twenty moves ago.

There's an undo button, thankfully, and a hint system that nudges rather than solves. All the puzzles are stored on the device, so the 'daily' set is available whether or not you have signal — great for a lunch break in a basement café.

What we liked

• Clever undo that encourages experimentation
• Whole puzzle pack lives on your phone
• Difficulty curve that sneaks up on you
