Double Tetrablocks

Double Tetrablocks - Play Online

Tetris. But doubled. Double Tetrablocks throws two boards at you. Same controls. Different grids. Your brain? About to fold. Made by ArtyGames, this is spatial chaos turned into a puzzle.

How to Play Double Tetrablocks

The mission is survival. Fill lines. Clear boards. Don't stack to the top. Simple? Not when you're juggling two fields at once. Double Tetrablocks tests your multitasking. Every rotation hits both grids. Every mistake compounds.

Dual Board Chaos

One input. Two boards. Press Up Arrow to rotate. Both tetrablocks spin. Press Left/Right Arrows. Both pieces slide. Down Arrow or Space Bar drops them fast. Mobile? Use the Rotate Button (bottom right) and on-screen arrows. Watch both grids. Place smart. One bad move wrecks everything.

Line Clear Logic

Fill a horizontal line completely. That board clears it. Upper blocks drop. Other board? Still your problem. Lines don't sync. Boards operate independently. Clear one side. Ignore the other. Game over when blocks hit the ceiling on either field.

Strategy Tips

Keep both boards balanced. Don't stack one side high. Prioritize the messier grid. Rotate early. Plan two moves ahead. Use Space Bar for hard drops when a spot is perfect. Build flat. Avoid towers. Spatial orientation wins here.
