Originally released by Damien Clarke and published by Miniclip, Bloxorz became one of the most-played browser puzzle games of the late 2000s. The premise is disarmingly simple: roll a 2×1 rectangular block across a suspended platform and get it standing upright over a square hole. But the tile layout, fragile bridges, special switches, and the block's unique movement geometry make each of the 33 stages a genuine spatial reasoning challenge. The block moves differently when upright versus lying on its long or short side — tracking that orientation is the core skill.
Use arrow keys to roll the block in any of the four cardinal directions. If any part of the block hangs off the edge of the platform, it falls and the stage resets. Get the block standing perfectly upright over the circular hole to complete the stage. X-shaped switches affect bridges; circle switches split the block into two separate pieces that can be controlled independently.
