Quadrix - Play Online

Two puzzle modes. One wooden board. Quadrix mixes Blocks (8×8 grid mayhem) with Classic Tetris (arcade speed hell). Grid-filling addicts? Start here.

How to Play Quadrix

Your mission is simple: Fill lines. Score points. Don't run out of space. Two modes, two rulesets. Blocks = strategy. Classic = reflexes. Both end when you mess up.

Blocks Mode - The 8×8 Grid Puzzle

Tap a block from the bottom row. Three shapes available at all times. Drag it onto the grid. Place it anywhere that fits. Fill a complete row or column? Boom. Line clears. Points earned. Clear multiple lines in one drop? Combo bonus kicks in. Game over when no block fits the board. Out of moves? Watch an ad. Get 3 fitting blocks to keep going.

Classic Mode - Tetris with Speed

Falling pieces. Rotating shapes. Fill horizontal lines to clear them. Speed ramps up every level. Arrow keys or WASD for movement. Spacebar for instant drop. Swipe controls on mobile. Tap to rotate. Long swipe down for hard drop. How many levels can you survive before the stack hits the ceiling?

Master Both - Strategy Tips

In Blocks, plan ahead. Look at all three shapes before placing. Save space for awkward pieces. In Classic, don't spam hard drops early. Build flat. Leave gaps only when you know the fix is coming. Speed kills at Level 10+. React faster or die.
