Welcome to your next evolution.
Tonight's competition is called "Yahtzee!"
This is pretty simple -- a game of Yahtzee! I will call your tribe's chat whenever people are online to play, and you will play a round of Yahtzee where you try to get the highest score (in this scenario what the computer player gets is irrelevant). The team with the highest score wins the Evolution, guaranteed another round in the game.
In the event of a tie, the team that completed their round (from the moment I rolled the dice the first time to the moment they locked in their last choice) in the overall fastest time will win. Good luck! I'll be on whenever this afternoon or this evening to do this. First come first serve.
