So you're at your friend Nick's house, bored as usual...that is, until he brandishes a hand-full of different colored, six-sided dice
There was two light green dice, two pink dice, two dark green dice, and two blue dice.
The rules were simple: the first to roll a seven on any two same-colored dice would win. Of course, the catch was that you had to win 'best of three'.
The light green dice --when rolled-- would cause the roller to become an anthro animal; the blue dice would affect the roller's age; the dark green dice would cause a full animal change; and the pink dice made a miscellaneous change (TG, size, mental attitude, switch bodies, etc.) However, being that Nick nor you have ever played this game, you would not know what dice color does what.
"I believe the honor of the first roll goes to the guest." Nick says to you
