Oubliettes

Oubliettes is a logic puzzle. Each grid hides a dungeon: work out where every wall is from the clues, with no guessing needed. Every grid has exactly one solution.

Rules

• The numbers along the edge give the number of walls in each row and column.


• Monsters and chests are never walls.


• Every monster sits in a dead end, and every dead end holds a monster.


• Every chest is in a treasure room: 3×3 open cells, one chest, one opening.


• Elsewhere, hallways are one cell wide and the whole dungeon is connected.

Features

• Campaign: 250 levels that are the same for everyone, in five difficulties (6×6 to 14×14), all open from the start.


• Endless: randomly generated grids in the difficulty you pick.


• Tutorial: a dungeon you solve step by step, one rule at a time.


• Drag to fill a row or column, undo and redo, progress and history saved after every move.


• Screen reader support, a magnifier for large grids, plain digits and a calm mode without animation.


• Endless grids are generated on the device. No ads, no tracking, no account.


• Original medieval music loops and sound effects, with volume sliders.

The app never uses the network: it does not ask for the Internet permission.
