Middles finds an Over at a low line and an Under at a higher line at different books. If the result lands between the two lines, both bets win. Whether a middle is worth it depends on the prices, the stakes and how often results land in that window.
Read the table
| Column | What it shows |
|---|---|
| Worst case | What you get back if only one bet wins, on this row's stakes. It is the worse of the two sides, and it is often a small loss. |
| hits | The line under Worst case: what both bets pay if the result lands in the window, as a share of your stake. |
| Play | The game and market. The start time is on the line under it. |
| Bets | The Over (low line) above the Under (high line), each with its book and price. |
| Gap | How far apart the two lines are, in the market's unit. |
| Window | The results that win both bets, such as 40.5–44.5. |
| Both win | The dollars both bets pay on a hit. It hides on narrow screens, where the hits line carries it. |
Sort by Worst case (the default), Gap or Start time. Neither the gap nor the hits figure is a chance of winning.
Work through one row
- Filter to the sports, markets and books you can use.
- Read the Over and Under lines. Check they are the same game, stat and period.
- Read the Window and list the results that would win both bets.
- Press the row. The side panel opens with the calculator on top: the worst case over the gap and window, the total stake, and the three outcomes.
- Change the total or the stakes and compare the Over-only, Under-only and both-win outcomes.
- Check both prices and rules at the books, then press Open both. It opens both books at once. If only one opens, allow pop-ups for Unjuiced from the address bar (steps).
Filters
- Min gap: the smallest distance between the lines.
- Both win at least: the least both bets must pay on a hit, as a share of the stake.
- Worst single side: the most you accept losing when only one bet wins.
Worked example
Over 43.5 and Under 46.5 are both -110. With $55 on each, the total stake is $110:
| Final total | Result | Net |
|---|---|---|
| 43 or below | Under wins, Over loses | −$5 |
| 44, 45 or 46 | Both win | +$100 |
| 47 or above | Over wins, Under loses | −$5 |
Here the worst case is −$5. Each winning $55 bet returns $105. The middle needs to land more than about 4.76% of the time to make money: 5 ÷ (100 + 5). That is the break-even rate the payouts imply. It is not an estimate of how often these totals happen.
Prices and pushes matter
A wider gap is not always better. Results spread differently by sport and market, and a pricier pair costs more when it misses.
Whole-number lines can push. If one bet pushes, its stake may come back while the other settles on its own. Check the edge results yourself.
If a book caps a stake, the calculator says so on that bet. If you change the stakes, compare both one-side outcomes again: they may no longer match.
Middles and arbitrage
An arbitrage pays something whichever side wins. A middle usually loses a little outside the window and pays more inside it. Some pairs do both, but the gap alone doesn't tell you that.
Troubleshooting
- The worst case is negative: that is normal for most middles. Read the hits line beside it.
- The gap is wide but the payout is poor: the prices make the one-side loss expensive.
- One line moved: redo the plan with the new line and price.
- No rows: clear narrow filters and check whether the slate has line gaps.
