About the game
Lying Oracle is a code-breaking game in the spirit of Mastermind. The oracle hides a code of four symbols. Build a guess and ask: a filled dot means a right symbol in the right place, a hollow dot means a right symbol in the wrong place. You have eight asks to crack it.
The twist is that the oracle lies exactly once per round, somewhere in its first five answers. So you cannot fully trust any single line; you look for the code that fits all the answers but one. Each round you also get one Reveal, which marks the lying row and shows the true answer, but if the oracle has not lied yet the Reveal is spent anyway. Runs are endless: every cracked code scores and the next oracle uses more symbols.
