One Lie is a free daily logic puzzle in which every statement about a hidden numeric code is true except one. These are the questions people ask most often.
One Lie is a free daily logic puzzle. You are given several statements about a hidden numeric code, and every statement is true except exactly one. You have three attempts to find the code.
Read the statements, work out which one must be lying, and use the remaining true statements to pin down the code. Enter the code and press ACCUSE. Full rules are on the how to play page.
