Hi Product Hunt, I’m Alex, the creator of Cavernum. My daughter asked to download a number-matching game. I got hooked too, finished it in two days, and wanted a tougher challenge. That became Cavernum. The rules are familiar: match equal numbers or pairs that add up to 10. Breakable rocks, voids, and one tile swap per level add a different challenge: deciding which matches to make and when. Every level is hand-tuned. A pair that looks tempting now can leave you stuck later. I wanted that satisfying moment when a board you couldn’t figure out suddenly makes sense. Cavernum is available on iOS and Android. Give it a try and tell me which level stops you. I’d love to hear where you found a clever solution and where the difficulty felt like too much of a jump.
