The player using taxi. The player pieces are mounted piggyback on neutral "carriers". On your turn, you roll up to three dice (1, 1, 2, 2, 3, 3), aiming for 4 or less --one die at a time. If you get 4 or less on two dice, you move twice the amount, if you get it on three, you move thrice. If you total more than 4, you're busted and your piece goes off board, plus a chip is added to the pot (initially seeded with 1 chip). As pieces move, they push those in front of them on the track. There are two exit tracks where you get to push pieces over the side. Whenever this happens, you also add a chip to the pot. You can get back on track only if there is a carrier piece available.
As you pass the pot, you grab the chips there (and seed it again with a chip). First player to 10 chips wins.
