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 feedback! We’ve improved touch accuracy in recent updates — please update and try again. The classic click/pop sound is back in recent updates — please update to get it. If it still happens after updating, email feedback@appholdings.org with device model + Android version + screenshot.

The game is dang addictive! but I can't give it 5 stars because the online multiplayer has problems, I always get disconnected for no reason, and if there's a network disconnection for even a nano second you get disconnected from the match, please fix that, make it retry to connect like 2-3 times before disconnecting completely, and also maybe add some way to communicate with others? they gotta know I'm teabagging them behind the screen.

Thanks, and agreed: brief network drops should not kick you out that aggressively. I'm tracking multiplayer stability and tightening reconnect handling. If this still happens on the latest build, please email feedback@appholdings.org with your device, Android version, and the rough match time so I can trace it.

this used to be my favourite app from ages, but with time the app should have atleast added the option of playing it with random strangers & players around the globe in automatic matching etc as most of the time I'm alone. Rating 1 is to bring into notice for the developers to do something about it and announc the news already.

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