Bloxorz
Roll a 1x2 block around a floating tile maze and drop it end-first into the square hole. Thirty-three levels, no timer, no mercy.
Damien Clarke built Bloxorz in 2007 and it became one of the handful of Flash puzzle games that genuinely deserve to be called classics. You roll a rectangular block across floating platforms toward a hole it only fits through when standing upright.
Everything follows from that one shape rule. Lying flat, the block covers two tiles and can cross thin bridges; standing up, it covers one tile and applies double the weight, which matters because orange tiles collapse under a standing block. Later levels add switches, bridges and a splitter that divides the block into two cubes you control separately. The level codes are part of the culture; people still remember them.

Tips
- Count your moves before you make them. The block returns to the same state every four rolls, so the parity of a path is fixed.
- Orange tiles only break under the standing block. Cross them lying flat and they hold.
- Falling off is instant and free of penalty beyond a restart, so use a deliberate fall to test a route you are unsure of.
