A superfecta requires picking the first four finishers in exact order. Box cost formula: n × (n-1) × (n-2) × (n-3) × base stake. A $1 superfecta box with 5 horses costs 5×4×3×2 = 120 combinations × $1 = $120. Superfectas offer huge payouts but are difficult to hit.
| Horses | Combinations | $0.10 Cost | $0.50 Cost | $1 Cost |
|---|---|---|---|---|
| 4 horses | 24 | $2 | $12 | $24 |
| 5 horses | 120 | $12 | $60 | $120 |
| 6 horses | 360 | $36 | $180 | $360 |
| 7 horses | 840 | $84 | $420 | $840 |
| 8 horses | 1680 | $168 | $840 | $1,680 |
A superfecta bet requires you to pick the first four finishers in exact order. If you bet a $1 straight superfecta on horses 2-5-3-7, they must finish exactly 1st, 2nd, 3rd, 4th in that order for you to win.
Superfecta box cost = n × (n-1) × (n-2) × (n-3) × stake, where n is the number of horses. For example, a $1 box with 5 horses: 5 × 4 × 3 × 2 = 120 combinations × $1 = $120.
A key superfecta uses one horse in a fixed position (usually first) with other horses filling the remaining spots. This reduces cost significantly. Keying one horse first with 4 others costs 4 × 3 × 2 = 24 combinations instead of 120 for a full 5-horse box.
Superfectas are best in races with clear favorites that may not win but will likely finish in the money. Large fields offer better value. Many professionals key a strong horse and use longshots underneath for big payouts.
Most tracks offer $0.10 minimum superfectas, allowing you to box more horses affordably. A 10-cent box with 6 horses costs 360 × $0.10 = $36 instead of $360.
