Quick reference — most common terms
If you only learn ten betting terms before the 2026 tournament, learn these. Each row links to the full alphabetical entry below.
| Term | What it is | When you use it |
|---|---|---|
| 1X2 | Three-way market: home win / draw / away win | Default market for picking the 90-minute result |
| Asian Handicap | Goal handicap on the favourite (often in 0.25 increments) | Tight market when one side is a clear favourite |
| BTTS | Both Teams To Score — yes/no | Two attacking sides, want exposure independent of who wins |
| Over/Under (O/U) | Total goals above or below a line (often 2.5) | Reading the matchup pace rather than the winner |
| Outright | Tournament-long bet (winner, top scorer, group winner) | Long-hold positions across the 39-day tournament |
| Decimal / American odds | Two notations for the same price | Decimal in EU/AU, American in US books — convert before comparing |
| Implied probability | 1 / decimal odds, expressed as a percentage | Comparing a book's price to your own model |
| Vig (juice / overround) | Book's margin baked into the odds | Comparing operators — lower juice = better long-run value |
| Closing-line value (CLV) | Your odds vs the closing odds at kick-off | The single best leading indicator of a winning bettor |
| Unit | 1–2% of bankroll, your standard stake size | Discipline mechanism — every stake measured in units, not currency |
A
- Accumulator (parlay)
- A single bet combining 2 or more selections. All legs must win for the bet to settle as a winner. The combined odds multiply, producing larger payouts at lower probability.
- American odds
- US-style odds notation. Negative numbers (e.g. −150) show the stake needed to win 100. Positive numbers (+200) show the win per 100 staked. See Decimal odds for the European equivalent.
- Arbitrage (arb)
- Betting both sides of a market across two operators where the combined implied probability is below 100%. Yields a guaranteed profit regardless of outcome. Operators ban arb accounts aggressively; not a sustainable strategy.
- Asian Handicap
- Market that applies a goal handicap to the favourite, often in 0.25 increments. Designed to remove the draw outcome from 1X2. Tightest-margin market in football betting — see the betting types guide for a worked example.
B
- Bankroll
- The total amount allocated for betting across the tournament, separate from personal finances. Unit sizing is a percentage of bankroll — see the strategy & bankroll guide .
- BTTS (Both Teams To Score)
- Yes/no market on whether each side scores at least once during regulation time. Settles 0-0 as No.
C
- Cash out
- Operator-offered early settlement of an open bet at a calculated buyout price. Almost always priced below fair value — the operator earns a margin for the convenience.
- CLV (Closing-line value)
- The gap between the price you took and the line right before kickoff. Consistently beating the closing line is the strongest long-run predictor of bettor edge.
- Correct Score
- Bet on the exact final scoreline. Long-shot pricing; high variance.
- Cover
- To win an Asian Handicap or European Handicap bet by enough to settle on the spread.
D
- Decimal odds
- European-style notation. 2.10 means a winning USD 1 stake returns USD 2.10 (USD 1 stake + USD 1.10 profit). Default notation on every operator we review.
- Double Chance
- 1X2 variant covering two outcomes — home-or-draw (1X), home-or-away (12), or draw-or-away (X2). Insurance against the draw, at the cost of a shorter price.
- Draw No Bet (DNB)
- Win-or-lose market that refunds the stake on a draw. Mid-priced between the 1X2 win price and Double Chance.
- Drawdown
- The peak-to-trough decline in bankroll during a losing run. Even profitable bettors experience 20-30% drawdowns inside a single tournament window.
E
- Edge
- The expected return on a bet expressed as a percentage of stake. A 2% edge means USD 0.02 expected profit per USD 1 staked over a large sample.
- European Handicap
- Handicap market without push outcomes. Settled as home/draw/away with a goal adjustment applied first. Whole-goal spreads only.
F
- Favourite
- The team with the shorter price. In decimal terms, anything below 2.00 is the favourite side of a market.
- Fractional odds
- UK-style notation (e.g. 9/4). The first number is the win relative to the second, which is the stake. 9/4 returns USD 9 win on every USD 4 staked. Decimal = 3.25.
- Futures
- Long-running markets settling at the end of the tournament — see Outright. The outright odds page lists current futures across W88, 1xBET and BC.GAME.
H
- Handicap
- Generic term for any market that applies a goal adjustment to one side. See Asian Handicap, European Handicap.
- Hedge
- Placing a counter-bet on a different market to lock in a guaranteed return or reduce variance on an open position. Common on long-running outrights.
- HT/FT (Half-Time/Full-Time)
- Combined market predicting both the half-time and full-time result. Nine possible outcomes; longer prices than standalone 1X2.
I
- Implied probability
- The probability embedded in a decimal price, calculated as (1 ÷ decimal odds). A 2.00 price has 50% implied probability.
- In-play (live betting)
- Markets traded after the match has kicked off. Wider margins than pre-match; higher variance.
J
- Juice (vig, vigorish, margin, overround)
- The operator's edge built into the prices. A two-way market priced with 5% juice has total implied probability of 105% instead of the fair 100%.
K
- Kelly Criterion
- Mathematical formula for optimal stake size given an edge and the odds. Most bettors use fractional Kelly (0.25-0.5×) to reduce variance. Conceptual treatment in our strategy guide .
- KYC (Know Your Customer)
- Operator verification of bettor identity — passport or national-ID photo plus address proof. Triggered at first withdrawal or at a cumulative deposit threshold.
L
- Limits
- Per-bet maximum stake an operator will accept on a given market. Higher on top-flight 1X2 markets, lower on exotics.
- Line
- The specific price or spread an operator publishes on a market. "The Brazil line moved from −1.0 to −1.25" means the handicap shifted.
- Longshot
- A high-decimal-priced selection — typically 5.00+ — with low implied probability. Tournament outright futures sit in longshot territory for most teams.
M
- Margin
- See Juice. Industry-standard top-flight football margins run 3-5% pre-match, 6-8% in-play.
- Money line
- US term for the win-only market (no spread, no totals). Equivalent to 1X2 in football but with no draw outcome (US books typically exclude the draw separately).
O
- Odds
- The price an operator publishes on a market outcome. Sometimes a probability, sometimes a payout ratio, depending on format (decimal vs fractional vs American).
- Outright
- A long-running market settled at the end of the tournament — tournament winner, top scorer, group winner. See our outright odds comparison.
- Over/Under (Totals)
- Bet on total goals scored relative to a line (most often 2.5). Over wins if goals exceed the line; Under wins if they fall short.
P
- Parlay
- See Accumulator. US-equivalent term.
- Pre-match
- Markets traded before the match kicks off. Tighter margins than in-play.
- Push
- A bet that settles as neither a win nor a loss — the stake returns to the bettor. Common on whole-goal Asian Handicap lines where the result lands exactly on the spread.
R
- Rollover
- Synonym for Wagering requirement. "14× rollover" means turnover equal to 14× the bonus (or deposit+bonus) must be placed before withdrawal.
S
- Stake
- The amount wagered on a bet. Separate from the potential return.
- Sportsbook
- A licensed operator that takes sports bets. The 12 sportsbooks we cover are listed at /reviews.
U
- Underdog
- The team with the longer price. In decimal terms, anything above 2.00 on a two-way market is the underdog side.
- Unit
- A fixed bet size expressed as a percentage of bankroll — typically 1-2%. Used to standardise stake sizing across many bets at different odds.
V
- Variance
- The dispersion of outcomes around the expected return. Sports betting at typical edges has high variance — a profitable bettor will still have losing weeks routinely.
W
- Wagering requirement
- The turnover a bonus must be played through before winnings can be withdrawn. "14× on (deposit + bonus) at min odds 1.50" is a typical World Cup welcome-bonus formulation.
X
- xG (Expected Goals)
- Statistical estimate of how many goals a team should have scored from the shots they took. Sportmonks publishes xG for most major fixtures; useful framing for Over/Under value identification.

Bet responsibly
Sports betting is for adults (18+ in most jurisdictions, 21+ in some). Knowing the vocabulary is the start, not the finish — the operational discipline is in the strategy & bankroll guide and the welfare side is on the responsible gambling page.
