Bloxorz is a free online block sliding puzzle game where your only job sounds simple: roll a rectangular block across a suspended platform and drop it straight into a square hole. The catch? That block is tall, it tips over edges, and one wrong move sends it tumbling off the board entirely. You start over from scratch every time you fall.

With 33 increasingly difficult levels, Bloxorz introduces new mechanics as you progress – pressure-sensitive floor tiles that only support the block when it's standing upright, split switches that divide your block into two smaller pieces you control separately, and toggle bridges that open and close sections of the board. The controls are just the arrow keys, but mastering when to stand the block upright versus lay it flat is the real puzzle. Rushing always costs you. Patience and planning a few moves ahead is what gets you through the tougher stages.

Bloxorz is a perfect fit for fans of logic puzzles, brain teasers, and spatial reasoning games. If you enjoy games like Sokoban, block-moving challenges, or 3D puzzle games, this one will keep you thinking. It's commonly searched as a classic Flash puzzle game, a math brain game for kids, or a tricky logic challenge for adults – and it holds up across all those descriptions. No download, no sign-up, just pure puzzle-solving in your browser.
