Liars’ Letters is a word-based game inspired by Liar’s Poker, where players use letter tiles to declare word sets and challenge each other's claims. The objective is to outwit opponents by successfully declaring higher word sets while avoiding being called out for deception. The rules are similar to the card game, with players accumulating letter tiles based on the validity of their declarations. The game includes a unique rule allowing for an 'exact' challenge when players believe all possible words have been played, adding a layer of strategic depth.
