Everyone picks a suit to root for.
On the left line up 8 or so cards face down as the rack track and the 4 aces start at the gate.
The remaining cards shuffle up and flip over 1 @ a time. Whatever suit is flipped over, move the corresponding ace forward one spot, perpendicular to the cards you lined up on the left. Whatever suit is last, flip over your race track card on the left. Whichever suit that may be, move that suited ace backwards.
As the race continues, whatever Ace is LAST to pass a perpendicular face down card, flip the perpendicular card and a matching suited Ace card goes backwards.
IF I remember this correctly, it was a drinking game we played in high school LOL.
