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.

This is a great game for passing time with friends, with up to 8 players. The rules take about 2 minutes to understand, but you could play this game for days. The only problem is the hitboxes, which are really annoying when trying to hit a combo. The grid makes it confusing as to where you actually have to click, therefore registering some false info, which can derail the game in a sticky situation. It gets really annoying.

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.

What’s new

Hotfix: restored main-menu ad warmup so interstitial preloading resumes earlier and ad requests recover.
