To end the game with the most points, which are acquired by landing on prime number spaces and collecting coins.
The game board consists of a path of hexagonal spaces. Each prime number space is worth that many points (e.g., the 17 hexagon is worth 17 points), and other spaces may contain coins, reverse or roll again options, or a passport.
On each turn a player is able to choose which random number generator they will use. There are several options:
Dice – One or two dice can be rolled. If two are used, the results can be added or subtracted.
Spinner – The player can select a spinner with just four numbers, and the player controls which numbers appear on the spinner; or, the player can select a spinner with unequal regions and determine which numbers occupy the largest regions.
Coins – Players can choose to flip some of the coins in their bank, and move based on the result of the flip. When a coin is flipped, it is then removed from the player’s bank.
Players then move around the game board. Points are earned each time a player lands on a prime number space.
Bonus points are earned for the following:
- A bonus of 2n is awarded for landing on 2, where n is the roll of one die.
- A 50 point bonus is awarded for landing on both numbers in a prime number pair.
- A 50 point bonus is awarded for landing on two numbers in a prime number triplet; an additional 100 point bonus is awarded for landing on the third number.
- A 50 , 150 , and 300 point bonus is awarded for landing on two, three, or four of the “lonely prime” numbers (23, 37, 47, 53), respectively.
There are also several special spaces on the board:
Roll Again – Allows the user to take another turn.
Reverse – Allows the user to take another turn, but the player’s token moves back toward the start instead of forward.
Passport – Allows the user to move to any space on the board.
The game ends when one player reaches the end of the game board.
Winning the Game:
At the end of the game, the player who reached the end receives a 250 point bonus; the other player receives all of the points in the Remaining Primes area. In addition, both players receive 25 points for each coin in their bank.
The player with the most points wins.
