Possession And Rollercoaster - 2 Simple Dice Games

Rules of Possession

1. There is one six sided dice between 2 players.
2. Player A must only roll odd numbers, if he rolls an even number, player B takes possession of the dice.
3. Player B must only roll even numbers, if he rolls an odd number, player A takes possession of the dice.
4. Each time a player rolls, the number they roll is added to the overall score.
5. The player who is rolling the dice when the score reaches 60 or above wins.

Example of players playing the game:
Player A rolls 3
Player A rolls 2 (An even number)
(The overall score is 5)
Player B takes the dice (Because player A rolled an even number)
Player B rolls a 4
Player B rolls a 6
Player B rolls 5 (An odd number)
Player A takes the dice (Because player B rolled an odd number)
(The over all score is now 30)

Rules of Rollercoaster

1. Players have 5 six sided dice - a white score dice; a green multiplication dice; a red division dice; a blue addition dice and a black subtraction dice
2. First they roll the white score dice.
3. Then they roll the green multiplication dice and multiply the number rolled with the white dice by the number rolled with the green  dice.
4. Then they roll the red division dice and divide their score by the number they roll with the red dice.
5. Then they roll the blue addition dice and add the number they roll with this to their score.
6. Then they roll the black subtraction dice and subtract the number they roll with it from their score.
7. The player who, after rolling all the dice, has the highest score, wins
8. Why? - It makes the game suspensful because a player doesn't know their score until they've rolled all 5 dice.
