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.

Chain Reaction used to be a perfect game to enjoy with friends, but recent updates have made it frustrating. The new touch controls are unresponsive and make gameplay difficult and inaccurate. It’s lost the smooth, intuitive feel it once had. Please consider reverting or improving the controls — many longtime players like me just want the classic experience back.

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.

I can't believe this game! I'm sick and tired of clicking on an orb and having the wrong one activate! It's infuriating! And I have a VERY GOOD suggestion that should have been obvious to the developers. This game is designed to be played WITH other people, which is a huge problem. Most of the time, people are alone! What if someone wants to play but has no one around? It's ridiculous! You need to add a computer player as an opponent with adjustable difficulty levels. This is basic stuff!
