A daily 'guess the year' puzzle game where players have to find the single year in which 5 events took place. The events are presented one at a time, obscure ones to start with, but becoming more well known, allowing the player to use knowledge or deduction to guess a year after each one. The game gives feedback on how close each guess was. After the quiz the player can share their final score and a 'Wordle-style' results grid to challenge their friends. Whendle also keeps full statistics on their performance.
