Corona is a puzzle-style game, with players trying to collect as many chips as possible. The game board shows a circuit course of 12 smaller circles. Before each round, the players distribute 6 pawns on the course. One player then rolls all 6 dice and turns over the timer. Players now assign the dice to the pawns and try to determine the highest score possible. The player announcing the highest number before the timer runs out performs his move. Each pawn moves, in clockwise order, the number of spaces shown on it assigned die and scores 1 point for each pawn on the space it ends its move. If the player managed to meet or exceed his/her predicted number, the player receives a chip from every other player; if not, the player gives a chip to each player and sits out the next round. The game ends after a player ends up without chips, with twice the original number of chips, or after a predefined number of turns or a set amount of time. Corona was published in the Ravensburger Casino Series. The introductionary (and a few other) variation(s) from Corona were republished as 'Moonstar' in 1981 (by Avalon Hill). Moonstar was rethemed as 'Harun' in 1984 (by Edition Perlhuhn). In 1993 Corona was republished and got a new variant included as 'Orbit' (by Franckh-Kosmos).
