Block Out is a 3D block puzzle game similar to Tetris but with three dimensions. You drop 3D blocks into a 3D well and clear horizontal layers by filling them completely.

How do you play Block Out?

Use arrow keys to move the falling block on the X and Z plane, Q/E to rotate around the Y axis, W/S for X-axis rotation, A/D for Z-axis rotation. Press Space for hard drop. Fill an entire horizontal 5x5 layer to clear it.

How many levels are in Block Out?

Block Out has 30 levels split into three difficulty tiers: Tier 1 (levels 1-10) with a 3x3 well and basic shapes, Tier 2 (levels 11-20) with a 4x4 well and complex shapes, and Tier 3 (levels 21-30) with a 5x5 well and all shape types.
