TL;DR summary
An exacta bet requires picking the first two finishers in exact order. A straight exacta is one combination at base cost. A $2 exacta box with 3 horses costs $12 (3×2=6 combinations × $2). A $2 exacta box with 4 horses costs $24 (4×3=12 combinations). Key bets reduce cost by designating one horse to finish first or second with others filling the remaining position.
Important information
Common exacta questions
An exacta (also called a perfecta) requires you to pick the first two finishers in a race in exact order. Horse A must win and Horse B must finish second. It pays more than win/place bets but is harder to hit.
A box covers all possible order combinations of your selected horses. A 3-horse box covers 6 combinations (3×2). A 4-horse box covers 12 combinations (4×3). The cost is combinations × base stake.
A key bet designates one horse for a specific position. "Key #5 on top with #2,3,7" means #5 must win with any of the others second. This costs 3 combinations (one for each other horse) instead of a full box.
For an exacta box: Cost = n × (n-1) × base stake, where n is the number of horses. 3 horses: 3×2 = 6 combos. 4 horses: 4×3 = 12 combos. 5 horses: 5×4 = 20 combos.
A part-wheel (or partial wheel) lets you select different horses for first and second. "1,2,3 with 4,5,6" covers combinations where a horse from the first group wins and one from the second places. Duplicates are excluded.
