Moneyline and 1X2
A moneyline prices which side will win. Two-way markets list two selections; a football 1X2 market lists home win, draw, and away win. Check whether overtime, extra time, or a draw is included before comparing prices across sportsbooks.
Spread or handicap
A spread adds a scoring handicap before settlement. A basketball favourite at -4.5 must win by at least five points to cover, while the underdog at +4.5 can lose by four and still cover. Football Asian and European handicaps use different settlement structures, so compare the exact line and rules.
Total
A total prices whether the combined score finishes over or under a posted number. Half-point lines avoid a tie; whole-number totals can produce a push when the final score lands on the line.
Push and void
A push returns the stake when the result lands exactly on a whole-number line. A void also returns the stake, but for a rule-based reason such as a cancelled event or an ineligible market. Sportsbooks can settle postponements, overtime, draws, and no contests differently, so read the market rules before betting.
Implied probability
Implied probability converts odds into the chance a sportsbook is pricing into the market. Decimal odds of 2.00 imply 50%. Decimal odds of 2.50 imply 40%. The formula is simple: divide 1 by the decimal odds.
Implied probability is the starting point for every value discussion because it shows what the market is asking you to believe before you place a bet. Use the implied probability calculator to convert a quoted price.
Expected value
Expected value asks whether the payout is worth more than your estimated probability of the outcome. A bet can lose and still have been good value. A bet can win and still have been a poor price.
For decimal odds, use: EV = (Estimated Probability x Decimal Odds) - 1. A result above zero is positive expected value according to that estimate.
The value betting calculator applies this formula to an estimated probability and offered odds.
Overround
Overround is the bookmaker margin built into a market. If all possible outcomes add up to more than 100% implied probability, the excess is the margin. Bettors need to overcome this margin before they can have long-term edge. Use the vig calculator to calculate overround and normalised no-vig probabilities.
Line shopping
Line shopping means comparing the same outcome across multiple sportsbooks before betting. If one partner offers 2.05 and another offers 1.91 on the same selection, the better price immediately improves expected value.
This is why Oddly Likely connects strategy guides to the verified partner board. The easiest value often comes from taking the best available number.
Reverse line movement
Reverse line movement describes a price or spread moving against the side reported to have most tickets. The pattern shows that the published ticket share and price moved in opposite directions; it does not identify who placed the wagers or why the market moved.
It is not automatic proof of value. The signal is strongest when paired with ticket-vs-handle splits, timing, market size, and a fair-price estimate. The reverse line movement guide explains how to assess those signals.
Ticket percentage vs handle percentage
Ticket percentage measures how many reported bets are on a side. Handle percentage measures how much reported money is on that side. If a team has most tickets but much less of the handle, the average wager sizes differ between the two sides.
These figures cover the books or providers in the report, not the entire market, and a larger average bet is not proof that a bettor is informed. Use the split as context, then check the price, timing, limits, and news.
Closing line value
Closing line value compares the price you took with the final comparable market price before the event starts. Consistently beating that price over a large sample is a useful process signal, but it does not prove that every bet had positive expected value. The closing line value guide covers consistent price comparisons and tracking.
Payout fit
Payout fit describes how well a partner's withdrawal routes match the bettor's actual needs. Crypto, card, wallet, bank, and pay-style checkout routes can all behave differently depending on region, limits, account review, and bonus state.
Crypto withdrawal route
A crypto withdrawal route can improve speed and control, but it still depends on supported coins, chain choice, network fees, confirmations, account review, and minimum withdrawal rules. Crypto support is useful only after the odds and terms make sense.
How Oddly Likely uses these definitions
Formulas on this page use decimal odds and illustrative numbers. Operator-specific payment, promotion, and settlement terms are verified separately on each sportsbook review; they are not universal definitions.
For a complete worked process, continue with the value betting guide and then apply the terminology to the current market analysis board.
How these terms connect
Start with implied probability and expected value, then improve the price through line shopping. Use sentiment to explain movement and payout terms to judge whether the partner fits.
