About
Blast lines. Chain combos. Make the board erupt.
Drag pieces onto an 8x8 board and clear rows and columns. Fill a line in a single colour and it erupts in a colour surge, the showpiece the whole game is built around. No timer, no energy, no lives, no loot boxes.
THE SURGE
Every piece carries its own colour. Line up a full row or column in one colour and the board answers with light. Chase surges for bonus points, or just enjoy the blast.
POWER PIECES
Bombs clear a 3x3 area, beams sweep a full line, prisms recolour what they touch. They arrive through normal play, never through a paywall.
DAILY CHALLENGE
One shared board for everyone, every day, from one seed. One ranked attempt, Game Center leaderboards, and practice runs when the ranked one is done. Same puzzle, different outcomes: compare your board with friends.
MADE TO FIT YOU
Colourblind mode pairs every colour with its own symbol. Reduced motion keeps every effect readable. Prefer tapping to dragging? Tap-to-place fully replaces drag. VoiceOver labels throughout, and none of it sits behind a paywall.
BUILT FOR THE RUSH
Chunky clears, screen-filling surges, combos that heat up the longer you keep them alive. Every placement lands with sound, light and haptics tuned to feel great. And nothing fights you for it: no timers, no popups mid-game, no pressure. Just the next hit of a perfect clear.
FAIR AND OPTIONAL
Free to play. Rewarded ads are always your choice, and a single one-time purchase removes interstitials forever. No subscription, no gacha, nothing consumable.
SPEAKS YOUR LANGUAGE
Fully localised in more than 40 languages, so Kajai feels at home wherever you play.
