How to play
- Read the list of statements. Each guest says something about one other guest: that they are lying, or that they are honest.
- Honest guests always tell the truth and liars always lie. The puzzle says how many liars there are.
- Tap the guests you think are lying, then press Accuse. If your picks are exactly the liars, you solve the case.
- A wrong accusation is a miss and clears your picks. Three misses end the case. There is a daily case and 30 levels that grow bigger.
Controls: mouse or touch. Made by CalcoTools.
Tips and strategy
- Pick a guest and assume they are a liar: then check every statement against that guess.
- A statement from a liar is always false, so the opposite is true.
- Two guests who accuse each other cannot both be honest.
- Every case has exactly one solution, so keep checking until only one set of liars fits.
FAQ
- Is there always only one answer?
- Yes. Every case is generated from a hidden answer and checked against every possible set of liars, so exactly one set fits.
- Do I need to guess?
- No. The statements always give enough to work it out. Try assuming a guest is lying and follow the consequences.
- How big do the cases get?
- From four guests and one liar up to eight guests and three liars in the later levels.
