Welcome to a simulator of a real lie detector! Take a polygraph test using our built-in fingerprint scanner! To determine whether a person is telling the truth or lying, ask them to place their finger on the scanner and keep it there while making a statement. Then, the lie detector machine will detect whether it is false or true. Here, in our lie tester, you will experience an amazing animation of fingerprint scanning and a heartbeat chart with realistic sounds. All these features make you feel like you are using a real lie detector! This game is intended only for entertainment, jokes, and pranks. All results are randomly generated.
