About the game
Block Blast hands you a board covered in empty squares and a stream of block shapes to drop onto it. Fill an entire row across or an entire column down and that line wipes clean, handing the squares back to you.
Every shape you set down eats space, so the board tightens as you go. Watch the gaps: leave holes in the wrong spots and later pieces have nowhere to land, which ends the round. Clearing lines pushes your score up. It runs at whatever speed you like, so a quick break or a long session both work.
