🕯 OubliettesPlay
Oubliettes is a dungeon logic puzzle. All you get are the numbers down the edges: how many walls each row and column holds. Everything else has to be worked out by marking cells as wall or hallway, and every finished grid is checked against the rules rather than against luck.
The rules are few but they interlock: a monster always sits in a dead end and every dead end holds one; a chest lies in a 3×3 treasure room with exactly one way in; outside those rooms hallways are one cell wide, and all open cells are connected. When deduction runs dry you lay a checkpoint, try a cell one way and see what follows.
The campaign holds 250 levels across five sizes, from 6×6 to 14×14. Endless dungeons are generated fresh, the daily grid is the same for everyone, and the lessons show one technique at a time. The game runs in the browser with nothing to install, and a Levbee account keeps your scores in your profile.

PlayHow to play
- Start from the numbers. A line that already holds its number of walls fills with hallways; a line that needs every cell it has left fills with walls.
- Mark walls and hallways. Click a cell to cycle it: unknown, wall, hallway. The Wall and Hallway brushes lay a mark straight away, and dragging fills a whole row or column.
- Use the rules. The monster in a dead end, the chest in a room with one way in, one-cell hallways and connected open cells give deductions the counts alone do not.
- Lay a checkpoint. When deduction runs out, save the grid as a checkpoint, try a cell one way and come back to it when the try breaks a rule.
- Ask for a hint. The hint explains the reasoning a step at a time; the check button separately crosses out the marks that are wrong.

FAQ
Do I need to install anything or sign up?
No: the game opens in your browser on the portal page. A Levbee account is optional, but it keeps your scores, achievements and progress in your profile.
How many levels are there?
250 in the campaign: five sizes from 6×6 to 14×14, fifty each, grouped into chapters. On top of that come endless dungeons, the daily grid and the lessons.
Do the levels repeat?
Campaign levels are always the same, while endless dungeons are generated fresh: each one differs from the last and has exactly one solution.
Can a grid be solved by guessing?
By brute force, yes, but it takes a while: every grid has exactly one solution, and the hint shows the deductions that lead there without guessing.
Does it work on a phone?
The game is made for a computer: it is driven by mouse and keyboard, though it also opens on a tablet with those attached.
