Roll the 1×2 block across the floor and land it standing on the goal. A rolling-block puzzle — solve as many as you can before time runs out.
You control a block shaped like two cubes stuck together — 1×1 on the floor but two units tall. It can stand upright on a single cell, or lie down across two cells.
Swipe up, down, left or right (or use the arrow keys) to tip the block over one roll at a time. Standing, a roll lays it flat onto the next two cells; lying, a roll along its length stands it back up, while a roll across its width keeps it flat and shifts it one row or column.
The block can never roll off the edge of the floor or onto a missing tile — those moves are simply refused, so you can't fall. Your job is to manoeuvre it so it ends up standing upright on the single marked goal cell. Lying across the goal does not count; you must land on it exactly, standing.
Solve a level and a new, usually larger one appears at once. Floors grow from 5×5 toward 7×7 and start adding holes as your score climbs.
Your score is the number of levels you finish before the clock reaches zero.
The single idea that makes this puzzle click is that the block's footprint changes as it rolls, so think about its orientation, not just its position. A standing block needs one clear cell, but a lying block needs two clear cells in a line — over holes and near edges, the lying orientation is far more fragile. Before a roll, picture the two cells it will land on, not just the direction.
Work backward from the goal. To finish standing on the goal cell, your previous move must have been a lying block rolling up to standing — which means just before the end, the block was lying in one of the four cells next to the goal, oriented so that rolling toward the goal stands it up. Identify those approach squares first, then solve the easier problem of getting the block lying on one of them.
There is a handy rhythm for travelling in a straight line: from standing, roll, roll again, and you have moved three cells and are standing once more — useful for crossing open floor quickly and for lining up the parity you need. Counting cells in threes from the goal often tells you exactly where a standing block must start its final approach. And remember that because illegal rolls are simply refused, you can probe an edge safely: a refused move costs nothing but a moment, so use the walls to reorient without fear.
