About this game

A strategy game for 2 to 8 players.

The objective of Chain Reaction is to take control of the board by eliminating your opponents' orbs.

Players take it in turns to place their orbs in a cell. Once a cell has reached critical mass the orbs explode into the surrounding cells adding an extra orb and claiming the cell for the player. A player may only place their orbs in a blank cell or a cell that contains orbs of their own colour. As soon as a player looses all their orbs they are out of the game.

Game features both HD modes for larger (Pad) screens and the regular mode for all devices.

Each player can customise the colour & sounds of their orbs. A player can also turn tactile feedback (vibration) on and off.

I hope you have as much fun playing this as I have coding it.

I liked this game before so 4 stars but it hasn't improved that much even degraded since in my phone a side of the grid is gone in either 3d or 2d mode. The updates for the theme hasn't helped with the enhancement of the gameplay and graphics just makes it more of an eyesore. this game probably will be good if it's added a zoom function and the theme is gone and only animation additional for the reaction. All graphic problems can be addressed using a graphic or resolution adjuster.

Hey, the online multiplayer player mode is good, but sometimes the opponent cannot place orbs when top corners part is triggered, it says "cant place there" then the game is stuck even if we play a new game the same thing happens when top corners are triggered. please solve this issue. I am using an android

Thanks for the detailed report. We are investigating the online multiplayer top-corner "can't place there" stuck-state issue and working on a fix for an upcoming update.

Concept wise the app is really great, but the online multiplayer option is not at all working. It is showing connection failed error when I try to host a match or try to start a quick match.

What’s new

Chain Reaction has a brand-new look! Glossy glowing orbs, sparks on every explosion, a chain counter, a fresh menu and a new Settings screen. Prefer the original game screen? Settings > Look > Classic. On a slower phone, Effects > Reduced keeps it light (Auto picks for you). Also fixed: a rare crash with banner ads, a freeze when opening a game right after launch, and a game reset after two quick screen changes.
