This game is so much fun-especially when you have a large group of people to entertain. So many people can play, it's amazing. But the gameplay is a bit on the repeating side. New arenas (ice, slippery, maybe huge theater, a tiny table, or maybe one with falling walls) different sizes, or maybe different domino skills would be cool. Another interesting addition would be options like how heavy the dominos are, how many are in a trail, and how big the dominos are. Or, if adding a different arena is out of the question, arena size. Thanks for the great game!
