Cavernum is a number-pairing puzzle game for casual puzzle players of all ages. It does not require an account or sign-in. Descend into the Cavern of Numbers. Match two tiles that are equal, or that add up to ten, and clear a path through the stone. Simple to learn. Not always simple to solve. Each level is a cave with its own shape and its own problem. Clear tiles and the grid compresses, closing gaps and opening connections you couldn't see a move ago. Paths wrap around edges. Diagonals count. The board you start with is never quite the board you end up solving. The caves go deeper, and they don't stay simple. Void tiles open in the floor. Rock blockers wall off the routes you wanted. Gates and chests wait further down, past the point where guessing stops working. Four tools help when you're stuck: Hint, Undo, Swap, and Add Numbers. Use them well. Swap only works once per level, and there's no second chance at it. No account. No sign-in. Play anywhere, though ads need a connection. Cavernum is a puzzle you can pick up in a minute and think about for a lot longer.
