Sequential:

• Player and Computer take turns to roll a single die to compete against each other.
• At a player's turn, the player can roll or hold.
• If the player rolls a 1, his/her round score becomes 0 and his/her turn ends – it becomes the computer’s turn.
• If the player rolls a number other than 1, the number will be added to the round score.
• If the player holds, the round score will be added to the total score.
• Whoever reaches the goal (100) first wins the game.

Simultaneous:

• Rules are the same as sequential game, except:
• Player and Computer each roll a single die simultaneously to compete against each other.
• A turn ends if both player and computer stop rolling which means either rolls a 1 or holds.
• Whoever reaches the goal (100) first wins the game. If both player and computer reach 100 at the same turn, then it’s a draw.
