A box wager automatically places every possible non-empty combination of your selections as individual wagers. If you box three selections A, B, and C, you get 7 wagers: Single A, Single B, Single C, Parlay AB, Parlay AC, Parlay BC, and Parlay ABC. Your total stake is split equally across all combinations.

How many combinations does a box produce?

A box of n selections produces 2^n − 1 combinations. Two selections → 3 combos. Three selections → 7 combos. Four selections → 15 combos. Five selections → 31 combos. The number grows exponentially.

How is the stake split in a box wager on OwnTheLines?

On OwnTheLines, the total stake you enter is divided equally across all combinations. Each combination receives (total stake ÷ number of combos). Any amount that can't be divided evenly is added to the largest combination (the full n-leg parlay).

Can I box just two selections?

Yes. A box of two selections A and B produces 3 combinations: Single A, Single B, and Parlay AB. This is the minimum valid box. It lets you collect if either single wins while also going for the higher parlay payout if both win.

What is the advantage of a box wager over a straight parlay?

A straight parlay pays nothing if any leg loses. A box wager spreads your money over all sub-combinations, so you can still profit from the singles or smaller parlays even if the big parlay doesn't come through. It's a way to trade some potential upside for reduced risk.

What Is a Box Wager?

A box wager automatically generates every possible non-empty combination of your selections and places each one as a separate wager. Instead of betting on a single parlay where one wrong leg kills the whole ticket, a box spreads your stake across all sub-combinations, so a partial hit can still pay out.

The Core Idea

When you box a set of selections, you are saying: "Place every possible single and parlay that can be formed from these picks." The total stake you specify is divided equally across all combinations.

The formula for the number of combinations is 2ⁿ − 1, where nis the number of selections. The −1 removes the empty set (betting on nothing).

Combination Count by Selection Size

Selections (n)	Formula	Combinations
2	2^2 − 1	3
3	2^3 − 1	7
4	2^4 − 1	15
5	2^5 − 1	31
6	2^6 − 1	63

The number doubles, minus one, with each additional selection. Boxes of 5 or more selections can get expensive quickly.

Example: Box of 2 Selections

You select A and B and enter a total stake of $30. The box produces 3 combinations at $10 each:

Box A + B: $30 total ($10 per combo)

Single A$10
Single B$10
Parlay A + B$10

If A wins and B loses, your $10 Single A ticket pays off while the other two tick as losses. If both win, all three pay out.

Example: Box of 3 Selections

You box A, B, and C for a total of $700. That produces 7 combinations at $100 each:

Box A + B + C: $700 total ($100 per combo)

Single A$100
Single B$100
Single C$100
Parlay A + B$100
Parlay A + C$100
Parlay B + C$100
Parlay A + B + C$100

How the Stake Is Split on OwnTheLines

When you enter a box stake, OwnTheLines divides it equally across all combinations. If the amount doesn't divide evenly (e.g., $100 across 7 combos), the remainder is added to the largest combination, the full n-leg parlay, so your total outlay is always exactly the amount you entered.

Box of 3 · Stake: $100

7 combos · $100 ÷ 7 ≈ $14.28 per combo

Remainder: $100 − (7 × $14.28) = $0.04 → added to the 3-leg parlay

Final split: 6 combos × $14.28 + 1 combo × $14.32 = $100.00

Box vs. Straight Parlay

Straight Parlay

One ticket, all legs must win
Highest possible payout if all hit
One wrong leg = total loss

Box Wager

One ticket per combination
Partial hits still pay something
Total outlay spread across combos

Neither approach is objectively better. It depends on how much variance you are comfortable with. A box is a way of hedging across your own selections.
