StopotS is a trendy categories game, also known as Scattergories, "City Country River" or simply Stop.

At the first moment, categories are chosen to serve as a base for the game dynamics. Categories like: Names, Animals, Objects and so on are examples of it. Once they're defined, a random letter is given to players, and a new turn begins. All must complete each category using a word that starts with a randomized letter. Those who fill all categories first press "STOP!" button; after that, all remaining players have their answers stopped immediately. By voting, players analyze all the answers and verify if they're valid or not. 10 points are added for each acceptable answer, 5 for repeated answers, and none for bad ones. This process repeats until a limit round is reached.
