About

Labyrnt

Features
Read full description

Labyrnt is a daily maze puzzle designed as a small ritual. It is built with Apple Watch in mind, short, focused, and intentional, and carefully adapted to feel just as natural on iPhone and iPad. Each day presents a single shared maze, played one cell at a time. You only see your current position. There is no full map. Navigation is entirely swipe based, so every move is a decision made through memory, pattern, and feel. The daily maze is designed for a quick, focused session rather than extended play. When the day ends, the challenge ends. This keeps the experience fair, meaningful, and easy to return to. Emoji-style spatial cues are always visible to support orientation and memory. When progress slows, a minimal grid indicator appears to help players re-anchor themselves without revealing the correct path or reducing the challenge. Leaderboards are tied to each daily maze and are frozen once the day ends. Only plays completed on that day affect rankings. Your personal result is always visible for comparison. Past mazes that weren’t played on the day can be completed later from the archive. Each maze is a single attempt. Once finished, the result and that day’s leaderboard remain available for reflection and comparison, without altering history. Labyrnt is fully playable without sound. Optional sound and haptic feedback provide tactile confirmation, especially on Apple Watch, but are never required. System accessibility settings, such as Reduce Motion, are respected automatically. Labyrnt feels most natural on Apple Watch with one handed swipe controls and subtle haptics designed for short moments on the wrist. The same daily maze adapts naturally to iPhone and iPad, offering a comfortable experience on larger screens. The daily maze is free to play. Signing in with Apple and Game Center is optional and only used for saving archive progress, tracking personal stats, and appearing on leaderboards. One maze. Once per day. A small moment of focus, then you are done.
