numble

Every cell holds a number. Every wall between two cells holds an

operation. Trace a path from the entrance to the exit, and the

running total you carry out has to match the target.

Cross a × wall and your total multiplies by the number you land on.

Cross a ÷ wall and it divides — but only if the answer comes out

whole. If it doesn't, that wall is shut. Until you come back

carrying something else.

That's the puzzle. The board isn't fixed. It reshapes around

whatever number you're holding, so a route that was closed at 7 is

wide open at 14.

WHAT'S INSIDE

• 15 campaign levels, from a gentle 3×3 to a fiendish 6×6

• Endless mode — pick a difficulty, play as many fresh boards as you like

• Hints when you're stuck, three stars when you're not

Every puzzle has exactly one solution, and we prove it before you

see it. Boards are generated and then checked exhaustively — if

there were two ways through, or none, it never reaches you.

No timers forcing you. No lives to run out. Nothing to buy.

A note on AI: the code and the text on this page were written with

AI assistance. The puzzles are not — every board comes from a

deterministic generator and is then checked exhaustively by a

solver, so each one provably has exactly one solution. No board

reaches you unless there is exactly one route through it.
