RATION

Your piece slides until it hits a wall. To clear a stage, it must come to rest exactly on the goal — sliding past it doesn't count.

That single rule is the whole game. Everything else is you, working out the order of moves.

■ 100 stages across 5 worlds
Each world introduces one new idea, then combines it with everything before:
· Plain — learn to stop
· Stop tiles — halt where there is no wall
· Warp pairs — the board folds in on itself
· One-way tiles — the path stops being reversible
· Fragile walls — break once, and the board is changed for good

■ Every stage has a verified best solution
The shortest route is computed, not guessed. Three stars means you found it. Two means you were close. The number is revealed only after you clear, so your first attempt stays yours.

■ Expert mode
Clear a world perfectly and it reopens with collection points scattered across the board. Same stages, different problem — and a longer route to solve them.
