A middle bets over a low line and under a higher line, so a result between them wins both. Over 44.5 and under 47.5 at -110, $110 each, wins $200.00 in the middle and loses $10.00 otherwise, so it needs a 4.76% hit rate. Novig lists alternate strikes on many props (Novig docs, checked 12 Nov 2026).

## Worked example

Worked example: over 44.5 and under 47.5, $110 each at -110

| Result | Over | Under | Net |
| --- | --- | --- | --- |
| Below 44.5 | Loses | Wins | -$10.00 |
| 45 to 47 | Wins | Wins | $200.00 |
| Above 47.5 | Wins | Loses | -$10.00 |

```
middle: over wins + under wins
outside: one side wins, the other loses its stake
break-even hit rate = -worst / (middle - worst)
```

A middle is a cheap lottery ticket when the lines have moved apart. The margin on both sides is what you pay for it; the question is whether the chance of landing in the gap beats the break-even hit rate. Whole-number lines can push, which returns that side's stake.

## How to use it

1. Enter the low over line and its price.
2. Enter the high under line and its price, and the stake on each side.
3. Read the result in each zone and the hit rate needed to break even.

## Questions

### What is a middle in betting?

Betting both sides of a game at different lines, so a result between the lines wins both bets.

### How often do middles hit?

It depends on the width and the sport. In NFL totals, key numbers make some gaps far more likely than others.
