Remove all A from the deck and place them in a vertical column on the left. Deal 7 cards face down in a row across the top.
The A are the horses, with each suit being its own horse. The winning suit is the A that can reach the right-hand side first.
Cards are dealt from the deck one at a time, and the A of matching suit advances one slot. For instance, if 8
♥ is dealt, A
♥ moves up one slot.
Each time any horse reaches a new column with a top card face down, the top card is turned face up. The A matching that suit is moved back one slot.
