Six contestants play at a time. All of them are dressed as horses, and wear roller skates.
When Tani fires the starting pistol the race begins. The contestants have to skate out from their starting blocks and race to the finish line at the end of the road.
The first two contestants to reach the finishing line win the game, the other four lose.
In later games four (then reduced to three) small hurdles, each slightly higher than the previous one, were added in the middle of the road. The contestants have to step over these hurdles to carry on, dragging the back legs of their costumes (which are also on wheels) over as they go.
