Randamn is a multidirectional shooter where a mystic slot machine randomly selects the enemies. The player has to try to become the new demigod of randomness by conquering seven strange worlds each with seven stages of shooting. At the first stage the slot machine will select one enemy that the player has to defeat and for each new stage the number of randomized enemies will increase by one until it reaches the seventh and final level of the world. Each world consists of a single screen which the player can move around and shoot in all directions. To complete a stage all the enemies that spawn around him have to be shot. It is also possible to outsmart the enemies so that they kill each other. The player has seven lives and by completing a world an additional life is earned.
