Now FREE, to help you pass the time if you are isolating. Stay well, and play some games!

A fast moving, highly addictive turn-based strategy game for 1-4 players. You won't be able to put it down!

"Simple concept, mesmerizing graphics, totally addictive."

Place your atoms on the grid but - move carefully! - they will overload and explode if too many are placed together! Strategically balance risk and reward to capture your opponents' Atoms in a chain reaction explosion while protecting your own from counter attack.

Last Atom standing is the winner!

A modern day remake of the "Exploding Atoms" retro game from 1980, and still as addictive as ever.

Atoms is simple to learn but hard to master, with similarities to classic board games like Othello, Reversi and Go.

"Simple concept, mesmerizing graphics, totally addictive."

"I love love love this game. Can't get enough of it!"

"Worth playing friends for the shouts of panic when the board flips on a single chain-reaction!"

"Atoms is awesome! Chain reactions are awesome!"

"It's so much fun!"

"Forgot my iPad. Can't play Atoms. Worst day ever."

Thank You!!!

This is the closest version to spinchat’s version of “Chain Reaction” on the market! This is also the best looking version of this game available! I have my fingers crossed for even larger grid options (It lets you choose between 5x5, 6x6, and 7x7). Thank you so much for producing this wonderful version. 5 years ago there were none on the market. It’s worth the $1.99.

A YES for my library.
