Kiitos is a fast-tempo, card-based word game with novel, simple rules and deep, emergent game play.You are not trying to make a word with the letters in your hand, but with those letters and the letters that may or may not be in your opponents hands.The first player plays a letter and says a target word. The next player plays the next letter of the word from their hand if they have it. If they dont then they can play a different letter and change the target word. If they cant think of a word to change it to with the letters in their hand then they have to pick up the played letters into their negative pile. If a target word is completed the player who set the target word picks up the word into their positive pile.The game has two modes: Kiitos, where the words are built up from left to right and Super-Kiitos, where the words are built up in either direction. The full game flips dynamically between the two modes.
