Line fun puzzle game Blocks start on the edges of the screen and fall towards the inner blue box. The objective of the game is to stop the blocks from stacking outside the area of the grey box. To do this, you must rotate the box to collect different stacks of blocks on each face. Aim to connect 3 or more blocks of the same color. When they match up, those 3 blocks are destroyed, and the blocks above them slide down. Destroying multiple series of blocks grants combos, whose durations are indicated by a quickly receding outline around the outer box. You lose once a stack forms outside the outer boundary!
