This is a game my friend and I created. You use dice to play a full game of quidditch. You need 6 dice, although 3 will suffice if you cannot get 6.

First you roll 3 dice to find out which ball is in play.
If you roll a 3, 4, 5, 22, 23, or 24 the Snitch is in play.
If you roll a 6, 7, 8, 9, 18, 19, 20, 21 the Bludger is in play.
If you roll a 10, 11, 12, 13, 14, 15, 16, 17 the Quaffle is in play.

First we will describe what you do for the Quaffle.
Each player will roll on dice for pocessian of the Quaffle. The player with the higher roll gets the Quaffle. If both players roll the same number, the dice are rolled again.
Next, the player with the Quaffle may complete 0-3 passes. To try a pass, the player with the Quaffle rolls two dice, the other player rolls one dice. If the player with the Quaffle rolls the higher number, he continues his turn. If the player that does not have the Quaffle rolls a higher number, than he now has control of the Quaffle.
To shoot the Quaffle both players roll 2 dice. If 3 passes have been completed, then the shooter wins a tie. If 2 passes have been made, the defending player wins a tie. If 1 pass was made the shooter must have a higher total by at least 2. And if no passes were completed, the shooter must have a higher total of at least 3.
10 points are scored for every goal.

When the Bludger is in play, both players roll 2 dice, the higher total chooses which player the Bludger is hit at. If the total's for both players are the same, no one gains control of the Bludger. The player who has control of the Bludger chooses one of his oppenents opposing positions and will subtract one from that positions next role. If the Chaser is chosen then 1 is subtracted from all passes and shots on the next Quaffle pocession. For the Keeper, it is just for defending a shot.

When the Snitch is in play, both players role 3 dice. The highest total catches the Snitch. If both players have the same total, the Snitch gets away. Once the Snitch is caught the game is over and the person who caught the Snitch gets 150 points.

Most points wins, its that simple.
