Block Chain Buster

Tap blocks to change their colors, connect 4 or more blocks of the same color, and clear them in this simple and satisfying chain-based color puzzle game!

“Block Chain Buster” is a puzzle game where you tap red, green, blue, and yellow blocks to change their colors and connect matching blocks vertically or horizontally.

The rules are simple.
Tap a block to cycle through the colors. Connect 4 or more blocks of the same color to destroy them.

When blocks are cleared, new blocks fall in from the top.
If the falling blocks create another matching group, a chain reaction begins and more blocks are destroyed automatically.

Aim for 2 chains, 3 chains, or even massive 10+ chain reactions!
Plan your moves carefully, predict how the board will change, and create huge combos to reach a new high score.

【How to Play】

・Tap a block to cycle its color: Red → Green → Blue → Yellow → Red
・Connect 4 or more blocks of the same color vertically or horizontally to clear them
・New blocks fall in from the top after blocks are destroyed
・If 4 or more matching blocks connect after falling, a chain reaction starts automatically
・The longer the chain, the higher your score
・The game ends when you run out of color-change moves

The controls are simple: just tap the blocks.
However, every color change can completely alter the board, so choosing the right block is the key to creating bigger chains.

【Look for White “+1” Blocks】

White “+1” blocks occasionally appear during the game.

If you destroy a normal block next to a “+1” block, the white block is destroyed as well and restores one color-change move.

Even when you are running low on moves, using +1 blocks effectively can help you keep the game going.

【Activate COLOR BURST with Big Chains!】

Build up chain reactions to charge the COLOR BURST gauge.

When the gauge reaches MAX, you can choose one of the four colors—red, green, blue, or yellow—and instantly clear every block of that color from the board.

COLOR BURST can completely change the board, so deciding when to use it is an important part of the strategy.

Which color will create the biggest chain?
Should you use COLOR BURST now or save it for later?

Choose carefully and use it to set up massive chain reactions and higher scores.

【The Satisfaction of Huge Chain Reactions】

There is nothing better than watching your setup trigger one chain after another!

Blocks shatter with flashy destruction effects, and the visuals and sound become more intense as your chain count grows.

Create massive 10+ chain reactions and challenge yourself to beat your best record.
