This is a puzzler about destroying tiles and watching the remaining tiles compact together, gravitating towards the centre of the grid.

Select zones of matching tiles to destroy them in one go, scoring points and game bonuses the one you eradicate on one turn. The remaining tiles will move to fill in spaces left behind, so sometimes you need to plan out the order of destruction.

Watch out for incoming tiles which swoop in at the end of every turn. If you let your grid block their path, you lose.

A variety of bonus weapons are available including "Sliders" allowing you to switch the colour of a tile to join up nearby zones of matching tiles for even bigger combos!

There's a mixture of campaign levels where you have a specific target to achieve, and arcade levels which just keep going until you'll eventually overrun with tiles!
