After level 20
Infinite Bloom: the endless puzzle garden
When the 20 levels are done, the puzzles keep coming, tuned to what you find hardest, and every session grows a flower in the air above you.

What it is
Infinite Bloom is the endless mode. You reach it by passing level 20, and from then on every session is a bloom: five paper-folding puzzles drawn from the whole game, the holes, light and ink kinds and every fold from halving folds to diagonals. Passing a level leads straight into the next bloom, so you never have to choose what to play.
The puzzles are generated on your headset from seeds, using the same rules as the 20 authored levels. Every one is checked to be valid and to have a single right answer, so the mode does not run out.
A mix that follows you
- Missed puzzles come first. Up to two puzzles you missed in earlier blooms return at the start of a session, oldest first.
- Weak spots get more practice. The rest are drawn from the level types, weighted towards the ones where your accuracy is lower and away from the ones you already find easy. Every mechanic still appears.
- No repeats in a row. The same kind of puzzle never comes twice running, and answers you have recently seen are skipped.
- No pass mark. Every session grows a flower. A miss simply becomes a puzzle to practise.
The spiral garden
Each bloom becomes a flower of up to six neurons: a heart and a petal for each fresh puzzle. Petals take the colour of the kind of puzzle they practised, so a flower shows at a glance what that session was about. Flowers are placed on a spiral dome above the ring of level clusters, one turn further round each time, and each is joined to the garden by a faint stem.
At the end of a session the new flower glides in front of you, opens its petals, pulses three times and returns to its place. Then the next bloom starts by itself, with no menu in between. Read more about how your progress becomes a brain.
