Click the board to randomize the setup.
Each board position represents a house with a person living inside.
Each persons either always tells the truth or always lies.

Each position of the board, and hence each person, has up to eight neigbours.
The board will show a number between zero and eight in each position. This number represents a statement of the person who lives at this position, namely it tells you how many truth-loving neighbours there are for this position.
However, the numbers given by each of the three liars on the board are all wrong. Your task is to find the positions of the liars.

Click any position where you suspect a liar to be. The digit will turn black. (You can click the position again to undo this selection).
When you think you have found all liars, click the CHECK button. The system will then tell you whether you have won.

HINT button:
If you click the HINT button, the system will either show you a liar or undo a wrongly selected person.

SOLVE button:
Click the SOLVE button to see the solution.

The variants have different board sizes and/or a different number of liars.
