One-Line Dungeon
Offline path puzzle. Pay once.
$4.99 · Designed for iPad. Not verified for macOS.
Draw one continuous line through 137 handcrafted dungeon halls. Keys, swords, portals, and a daily dungeon, all offline. Paid once: no ads, no accounts, no purchases.
One line. One way out.
Every hall in One-Line Dungeon is a small stone board with a single rule: draw one continuous path from the start to the exit without crossing your own steps. It sounds simple until the dungeon starts placing keys behind doors, monsters in narrow corridors, cracked tiles that fall away behind you, and portals that fold the room in half. Every step you take is a step you cannot take back.
HOW IT PLAYS
Trace your route with one finger. The board lights up as the line grows, and the moment you step onto the exit, the hall is cleared. Undo a step, or restart and try a cleaner idea. Free local hints reveal one safe next step when you are stuck, with no currency and no timers.
THE DESCENT
The First Descent is a guided opening chapter of twelve halls that teaches each mechanic in play, not in a tutorial. Beyond it waits the Vault: four packs and 137 handcrafted levels in all, every one validated to have multiple valid routes, with stars for a clean clear and a crown for the perfect one.
EVERY DAY, A NEW DUNGEON
The Daily Dungeon is carved on your device from today's date, so everyone who plays gets the same hall, and nobody needs a connection to play it. Survival mode strings freshly generated floors together for as long as your line holds.
