Betting Numbers Explained

Bet types & conceptsBetting numbers

Betting slips are full of numbers and symbols — minus signs, plus signs, .5 lines, PK, EV. This guide decodes the common ones in plain English, with hypothetical examples only.

Key takeaways
  • It is a 1.
  • PK (pick'em) means there is no handicap — you simply pick the winner.
  • EV is expected value — whether a price is mathematically favourable over the long run, based on the implied probability of the odds.

Plus and minus

On a line, minus marks the favourite and plus marks the underdog. On a spread or handicap, the favourite's minus number is the margin it must overcome; the underdog's plus number is its cushion. On a moneyline, they show price — see the moneyline.

What -1.5 and +1.5 mean

A .5 line removes ties. On a -1.5 spread or handicap, the favourite must win by 2 or more. On +1.5, the underdog covers by losing by 1 or winning.

Example. -1.5 needs a 2-goal (or 2-point/2-run) win; a 1-margin win does not cover. See point spread and handicap betting.

PK (pick'em)

PK, or 'pick'em', means there is no handicap — the line is effectively zero and you simply pick the winner. If the game is a draw on a PK line, stakes are usually refunded.

EV and reading a line

EV means 'expected value' — whether a price is mathematically favourable over the long run, based on implied probability (see how odds work and value betting). For a deeper glossary of terms, see the betting glossary.
