Quick Answer

A partial wheel allows you to select different horses for each finishing position. Unlike a box (where all horses compete for all positions), you can concentrate your top picks in the win position while including more horses for place/show. This reduces cost while focusing bets on your highest-confidence selections.

Frequently Asked Questions

What is a partial wheel bet?

A partial wheel lets you select different horses for each position in an exotic bet. Instead of boxing all horses equally, you can "weight" certain positions—using your top picks for first while including more horses for later positions. A $1 trifecta with 2 horses in 1st, 4 in 2nd, and 4 in 3rd creates specific combinations rather than a full box.

How is the cost calculated?

Multiply the number of horses in each position, then multiply by the stake. The calculator automatically excludes invalid combinations (same horse in multiple positions). For a 2-4-4 trifecta, the maximum is 32 combinations, but duplicates are removed.

When should I use a partial wheel vs. a box?

Use a partial wheel when you have strong opinions about certain positions. If you're confident about the winner but unsure about place/show order, wheel your top pick with several others. This is often cheaper than a full box and concentrates bets where you have an edge.

What is the difference between a key and a wheel?

A "key" bet has one horse that must finish in a specific position. A "wheel" includes multiple horses in each leg. A "partial wheel" combines both concepts—keying some positions while wheeling others. This offers maximum flexibility.
