Block Blast
Block Blast is a free browser puzzle game where you match colored blocks, clear lines, and chain combos for higher scores. It runs at blockblast.run with no download required, and the site also hosts 300+ other casual titles across block, puzzle, and unblocked game categories.
Most block puzzle sites host a single Tetris clone. Block Blast bundles its namesake matcher alongside 42 block games, 79 puzzle games, and 120 unblocked titles aimed at school-break play, so one URL covers multiple genres instead of sending players elsewhere.
Controls use arrow keys to move and rotate pieces, spacebar for instant drops, and P to pause. The scoring system rewards chain reactions and multi-line clears, and a global leaderboard tracks high scores. The game works on desktop and mobile browsers without an account.
