Logical Chain Reaction Free

Chain Reaction is a logical game designed specifically to practice spatial thinking and prediction skills. It has built-in 100 levels with varied difficulties. Each level contains colored blocks arranged in a chess-like manner. Two neighboring blocks cannot have the same color! That’s the key!


Each block (square or hexagon) can be rotated over other given block. Player’s goal is to destroy all the blocks on each level. But there’s a catch! The level must be solved by using the smallest number of moves made by the player.


The game is not as easy as at first glance. It can only be squares or hexagons, but there’s more to it. Each level has limited number of moves that the player can do. This number is not taken from outer space and did not come through some stargate. It’s real. It means that there exists at least one possible solution for given level with that specific number of moves (meaning how many blocks need to be rotated over each other in order to clear the stage).


To rotate any block in desired direction first it needs to be selected. Selection is done by single touching or holding finger over given block. Special touchpad will emerge after that.


Before jumping into block rotating frenzy, one needs to understand a few basic rules:

- squares can be rotated in four directions,

- hexagons can be rotated in six directions,

- blocks next to each other cannot have the same color,

- when rotating block falls onto another block – the original one will be destroyed,

- if two blocks rotate simultaneously into the same position – all blocks at that spot will dissolve,

- when player rotates selected block to new position it can cause color conflict with neighboring blocks,

- newly rotated block will push away other blocks with the same color (causing a chain reaction),

- blocks that don’t have any neighbors in all eight directions will dissolve!

And that’s how winning is done! Those rules are thoroughly explained inside the game. Enjoy! There is also an in-game system for ranking solutions found by the player.

Golden Star rating is received when the level is solved using the smallest possible number of moves – each level has a guaranteed solution with this number of steps. That's important! Please remember that, even if sometimes level seems impossible to be solved.

Silver Star rating is received when the given level is solved using one extra move. It's possible to restart level later and try again to beat the previous score.

Level is marked with Bronze Star rating when it’s solved using two additional moves.
