I don't even have to do the math to tell you that would involve a ton of rolls.- A game of horse-race. You place a line of 12 blocks and on top of the first block of each line you place a custom head or a button or anything small. You roll d6 and every time you roll a 6, your horse moves one block further. You roll in turns, so the first to get to block 12 wins (Inspired by shagai)
1-: back a space
2-4: stay
5-6: move up
Is a faster game.
