Boxing horses: every order covered
A box covers every order of the horses you pick. An exacta box of two horses wins if they finish first and second in either order. A trifecta box wins if your horses fill the top three in any order.

Key takeaways

- Keying a strong horse cuts the cost a lot.
- Payouts come from a pool, so they are not fixed in advance.

Exacta box costs
| Horses | Combinations | Cost at $1 | Cost at $2 |
|---|---|---|---|
| 2 | 2 | $2 | $4 |
| 3 | 6 | $6 | $12 |
| 4 | 12 | $12 | $24 |
| 5 | 20 | $20 | $40 |
| 6 | 30 | $30 | $60 |
Cost = combinations x base bet.
How boxes are priced
Each order is a separate bet. A three-horse exacta box covers six orders, such as 1-2, 2-1, 1-3, 3-1, 2-3 and 3-2. Only one order can win, so five of the six bets lose even when you hit.
That is why a box must pay well to make a profit.
Trifecta box costs
| Horses | Combinations | Cost at $0.50 | Cost at $1 |
|---|---|---|---|
| 3 | 6 | $3 | $6 |
| 4 | 24 | $12 | $24 |
| 5 | 60 | $30 | $60 |
| 6 | 120 | $60 | $120 |
Many tracks allow 50-cent trifectas.
Keys and wheels
A key puts one horse in a fixed spot. A trifecta with a key on top and three others underneath costs 6 bets, against 24 for a four-horse box.
A wheel uses one horse with all others in a spot, which helps when you love one horse but not the rest.

When boxes make sense
Boxes fit races where you like a few horses about equally and cannot rank them. If one horse stands out, a key is cheaper.
In big fields with a strong favorite, boxes often pay less than they cost.
Floor rules
Box terms
Know before you sit
- Box
- Every order of chosen horses.
- Key
- One horse fixed in a spot.
- Wheel
- One horse with all others.
- Base bet
- Stake per combination.
Partial boxes
Some players box their top two horses in the first two spots and add more horses for third. This costs less than a full box and still covers likely orders.
Most betting apps let you build these with a "part wheel" option.
Box vs key cost (trifecta, $1)
| Ticket | Combinations | Cost |
|---|---|---|
| Box 4 horses | 24 | $24 |
| Key 1 over 3 | 6 | $6 |
| Key 1 over 4 | 12 | $12 |
| Top 2, then 4 for 2nd and 3rd | 12 | $12 |
Example tickets.
Superfecta boxes
A superfecta box covers the top four in any order. Four horses make 24 combinations, five make 120 and six make 360, so a 10-cent base bet is common.
At 10 cents, a five-horse superfecta box costs $12. Payouts can be large, but hits are rare.
Common mistakes
- Boxing too many horses
- Costs explode.
- Forgetting each combination is a bet
- Read the total.
- Boxing when one horse stands out
- Use a key.
- Expecting fixed payouts
- Pools change.
