About
One move. A chain reaction. A completely different game.
Critical Mass 2 is a strategy game of charged cells and explosive reversals. Build your strength, capture your opponents’ cells and set off cascades that can turn the board in your favour. Every move counts—and a commanding lead can disappear in a flash.
Play solo against four AI difficulty levels, from Easy to Expert, or share a device with friends in games for up to four players.
TWO WAYS TO PLAY
Choose Classic for explosive chain reactions, or try Critical Mass 2 Go—a distinctive twist on Go, with its own strategic challenges.
MAKE EVERY MATCH YOUR OWN
Mix and match gameplay options, including Power, Timer, Proximate and Pre-fill, to find your favourite way to play.
STRATEGY WITH SPARK
Luminous cells, flowing energy and a moving cosmic backdrop bring every contest to life. Reduced-motion options let you dial back the animation.
Easy to pick up, with plenty to discover as you learn when to build, when to strike and when to set the whole board in motion.
Featuring original music composed by Gabriel Berger.
