Common questions

How do I clear a wrong placement?

Tap the cell, then tap Erase. Wrong placements stay until you erase or the run ends.

Why does the Hint button cost a heart?

Hints are the safety net. They're powerful — they reveal a forced cell or flag a wrong placement — so each hint costs one of your three hearts. With one heart left, hints are disabled.

What happens at zero hearts?

Run ends. Your in-progress save is cleared and you'll start again from floor 1.

How do I read the rules of a variant card?

Each card description is shown in the card-pick sheet between floors, in your device language. The Killer cage sums sit in the top-left corner of each cage. Renban lines, thermometers, and XV/odd-even markers are drawn directly on the board.

Are puzzles always solvable?

Yes. Every floor's puzzle is generated and verified to have exactly one solution under the active rule set before you see it.

Does Loop need internet?

No. The game runs entirely offline. We don't collect any data — see the privacy policy.
