Kajai

Light up the line.

A calm, luminous block puzzle for iPhone and iPad. Place pieces, clear lines, and when a line is all one colour, it surges.

No energy timers. No loot boxes. Ever.

A Kajai game in progress: glowing blocks in blue, purple, pink and amber on the board, a live combo, and three pieces waiting in the tray.

Colour surge

Clear a line in a single colour and it erupts into light. Chasing surges is the whole game.

Power pieces

Bombs, beams and prisms. Earned by playing, never bought.

The daily

One seeded puzzle, identical for everyone on Earth, once a day. Game Center leaderboards included.

For every player

VoiceOver, tap-to-place, colourblind symbols, reduced motion. Built in from the first line of code.

Kajai is the block puzzle we wanted to play: calm instead of loud, generous instead of grabby. No energy timers. No loot boxes. No ads ambushing you mid-move. Just you, the board, and the lights.
