A puzzle where numbered blocks become roads. Drag a block and its number drops by 1 for every square it moves. When it hits exactly 0, the block locks in place and turns into a road. Turn every block into road and connect the two dots to clear the stage. That's the whole rule. But the lower a number gets, the less room you have to move — slide carelessly and the last road won't reach. Which block, in which order, to where: a classic logic puzzle about thinking ahead. HOW TO PLAY 1. Drag a numbered block — each square it moves costs 1 2. At exactly 0, it locks in place and becomes road 3. Turn every block into road and connect the two dots 4. Walls and finished roads block the way — order matters 5. Made a mistake? Tap a road to pick the block back up WHAT KIND OF PUZZLE IS IT?
