You have to crack the safe codes by throwing dice to earn victory points. Each safe card is worth 2 through 5 points. The player with the most points at the end of the game wins. When it is your turn, you must roll all 5 dice. After each roll, you must set aside at least one die. The pips of this die tell you on which number you can put a marker on one of the three revealed safe cards. Now you must decide to stop or go on. If you go on, you roll the remaining dice and have to put aside at least one die and, therefore, another counter on a safe card. If you stop, you can take a safe card that has all its code numbers covered by markers. If you roll only pips that are not on any of the revealed safe cards, your turn ends immediately and you cannot claim any of the completed safe cards.
