In a 4 by 4 grid with a total of 16 tiles each containing one word find four sets of items that share something in common. Categories vary from “a fish” and “something you would see at a party” to “part of a phrase” and many more. However, categories will always be more specific than just “5-letter-words,“ “names,” or “verbs.” 

Each puzzle has exactly one solution and each of the 4 groups has a color assigned to them to indicate the groups difficulty from easiest to guess to toughest to guess (yellow>green>blue>purple). These colors are revealed once a group is guessed correctly. You have a maximum of 3 mistakes, after which the game is lost and the answers are revealed. Hints such as “one off” may be given if you select a group of 3 correct and 1 incorrect item.
