In Triangulation, two teams compete to guess their opposition's secret word. The spymaster on each team writes three clues, which are then revealed one at a time. The opposition can guess after each of the first two words, but if they fail, the spymaster's team sees the third clue and makes a guess. The trick is to write three clues that only make sense when all three are revealed. It's a simple concept that makes for a quick and accessible party game that rewards clever thinking.
