What is an Exacta Box?
An exacta box is a horse racing bet where you select multiple horses to finish first and second in either order. Boxing your exacta means you win if any of your selected horses finish 1-2 in any combination.
For example, if you box horses 3, 5, and 7, you win if they finish: 3-5, 5-3, 3-7, 7-3, 5-7, or 7-5. The tradeoff is that boxing costs more because you're placing multiple bets.
The minimum exacta box requires 2 horses (2 combinations). A 3-horse box has 6 combinations, 4-horse box has 12 combinations, and so on.
