MINUM is a high-tech version of the popular game "twenty-club" from the last millennium. Once it was played with a wrist watch as a timer ... ridiculous! The gameplay is simple: when you hear the Minum-o-Mat sound, a shot small glass full of beer is drunk - of course you may also use water instead. The normal repetition time is 1 minute. There's not much time to refill the glasses! The duration of the game is also controlled by the number of rounds. A value of 20 is usually good starting point - the hard-nosed should switch to "OPEN".
