Ozvenka: Echo Logic Puzzle

Ozvenka is a logic deduction puzzle: send echoes from the edge of a cave and use their outcomes to locate hidden stones. The cave is dark. Stones lie hidden somewhere inside it. You put nothing into the cave — you send an echo in from the edge and listen for where it comes out. Either it appears somewhere else, or a stone swallows it, or it returns the way it went. From what you hear, where the stones lie can be worked out. Not guessed. Worked out. • 120 caves across ten worlds, plus a daily cave — one a day, the same one for everyone • Every cave's par is the smallest possible number of echoes. It is not the author's estimate: the same solver that verified the cave computes it • You never have to guess: every cave has exactly one answer, and the echoes can always settle it • When you get it wrong, the game says why: whether an echo contradicts your reading, or whether you simply have not heard enough yet • The hint is computed from what you have actually heard. It never points at something that is not in the cave • Once you solve it, you see where the echoes really went • Slovak, English and Czech No ads. No accounts, no sign-in. Gameplay works offline: every cave and every daily is inside the app, so it plays on a plane. Gameplay statistics stay on your phone. Purchasing and restoring need a store connection. The optional Moonlit Hall adds 60 new caves with a one-time purchase. The original 120 caves, daily challenges, guided introduction and hints stay free.
