Chroma Blocks: Block Puzzle

One colour. One line. The whole board goes up.

Chroma Blocks is a free colour block puzzle with a twist that no other block game has: clear a line made entirely of ONE colour and every single block of that colour is wiped off the board at once. That's a COLOUR BLAST — and chaining them is where the big scores live.

HOW IT PLAYS

Drag block shapes onto the grid. Fill any full row or column and it clears. No timer, no lives, no pressure — play one relaxing round on the bus or chase a high score for an hour. Easy to learn in ten seconds, genuinely hard to master.

★ COLOUR BLAST — THE HOOK

Any line you clear in a single colour detonates that colour everywhere on the board. Set one up on purpose and you'll trigger chain reactions, combo multipliers and a screen full of confetti. Learning to see the blast before it happens is what turns a good run into a great one.

★ TWO BOARDS, TWO GAMES

Start on the classic 8x8 board, then switch to the roomier 10x10 for longer, more strategic runs. Each board keeps its own best score, so you have two records to beat.

★ POWER-UPS WHEN YOU'RE STUCK

Score points, earn charges, spend them when it counts:
- Colour Clear — vaporise every block of one colour
- Shuffle — swap your pieces for a fresh set
- Bomb — tap anywhere to blast a 3x3 area
- Ultra — a once-per-game full board wipe when things get desperate

★ SKINS YOU ACTUALLY EARN

Every round pays out coins. Spend them on board skins — Midnight, Forest, Ember, Aurora, Royal — that repaint the blocks, the background and the whole mood of the game. Eight skins in all, three free from the start.

★ COMPETE AND COLLECT

Global leaderboards for both board sizes and ten achievements to unlock, through Google Play Games. Signing in is completely optional — the game plays fine without an account.
