I like the mechanic of rolling your dice around and selecting which dice to save. Because it's Yahtzee, however, I found the game was way easier if I just went for a Yahtzee every time, since you can roll 4 times in one direction to land on the same number. Very cool idea though and I would love to see it expanded.
Our team was also inspired by Yahtzee, so it's cool to see how we went in different directions.
