Drag the three offered pieces onto the 8x8 grid. When a full row or column is filled, it clears and scores points.
Each cleared line scores points; clearing multiple lines at once and back-to-back clears build a combo multiplier for big bonuses.
Keep the board flat and leave open space for big pieces. If none of the three pieces fit, the game is over.

Block Blast is a free online block puzzle game that takes the addictive 8x8 grid formula and polishes it to perfection. The rules are simple enough to learn in seconds: you get three random tetromino pieces per turn and drag them onto the board. When you fill an entire row or column with blocks, the line bursts and clears, freeing up space and scoring points. The catch is that, unlike classic falling-block games, nothing drops from above - you place every piece exactly where you want it, so victory is purely a matter of planning ahead. The strategic depth comes from the combo system: clearing lines on consecutive placements builds a combo counter, and combo clears pay out multiplied bonuses, so the best players sequence their moves to keep chains alive. Because the game ends when none of your three pieces fit, every placement matters - a careless move can leave a single awkward hole that ruins an entire run. Block Blast is perfect for short sessions and long marathons alike: one more run is always tempting when you are chasing a new personal best, and your high score is saved automatically so you always have a target to beat. The clean neon visuals and satisfying clear animations make every line burst rewarding, and the game runs smoothly on desktop, tablet and phone with full mouse, trackpad and touch support. There is no download, no installation and no account needed - just open the page and play. If you love Tetris-style line clears, sudoku-adjacent spatial planning, or simply a relaxing puzzle with real depth, Block Blast deserves a spot in your daily rotation. Stack smart, clear big, and see how far you can push your combo before the grid fills up.
