About this game

Chain Reaction is a fresh puzzle concept: place pieces, trigger the reaction, and watch it cascade across the board.

Every level can be solved — but earning all 3 stars is a different story. That takes real thinking about setup, order, and efficiency.

FOUR WAYS TO PLAY

• Levels — fresh level added daily!

• Challenge — one fixed board, identical for every player on every device. Same start, same rules, no randomness. Your score is the longest chain you can build and detonate, and how few moves it took you to get there.

• Zen — a full-screen board sized to your device. No goals, no pressure, no stars to chase. Just set off reactions and watch them go. Your progress saves itself.

• Custom — pick any board size you like and play in the sandbox.

We're actively improving the game based on how people play — new levels and features are on the way.

Coming soon: 1v1 mode, so you can challenge other players head-to-head.

Privacy note: your Play Games ID is used only to put your score on the leaderboard and attribute any level you submit to the community. No other personal info is collected.

Works completely offline.
A fresh puzzle: easy to solve, hard to 3-star. Plus a calm Zen mode.

What’s new

• Hints no longer earn stars — the run is scored, and stated, but not banked.
• Fuse stays with you: take a hint, play it, and ask again without summoning him.
• He only offers a reshuffle that can actually change the board.
• When it can't help, he says so and offers a hint — or a random shuffle, your call.
• He steps off the board while a reshuffle plays, then tells you what he turned.
• Fuse is back on the spinner level after its intro popup.
