Your box arrives

Nine hand-picked puzzles, cleaned and complete, posted to your door each month.

Solve at your own pace

Take all the time you like. On the Relaxed plan there's no clock at all, so a stubborn puzzle waits as long as you need it to.

Send it back, free

A prepaid InPost label is in every box. Drop it at any locker, and your next set of puzzles ships.

Exercise for your hands and your mind

Mechanical puzzles work spatial reasoning, memory, and fine motor skills — and unlike a crossword, they get you away from a screen. Research links regular puzzle-solving with sharper problem-solving and better focus at every age.
