Dungeon logic puzzle: find the walls from the row and column counts
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.
Daily: one dungeon a day, open on its day only.
Tutorial: lessons you solve step by step, one technique at a time, then practise alone.
Hints that teach: where to look, then why, then which cells.
Share a solved grid as text, without its solution, and dig the one a friend sent.
Drag to fill a row or column, undo and redo, progress and history saved after every move.
Screen reader support, a magnifier and two-finger zoom 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.
