A
Agent Meta Valorant

The current strongest set of Valorant agents considered optimal in competitive play.

Example: Teams running an off-meta agent composition to counter a dominant agent meta can be undervalued by sportsbooks unfamiliar with the shift.

American Odds

Odds expressed as a positive or negative number relative to $100. Negative means the amount you must bet to win $100; positive means how much you win on a $100 bet.

Example: Sentinels at -150 means you bet $150 to profit $100; Fnatic at +130 means a $100 bet profits $130.

Asian Handicap

A handicap betting format that eliminates the draw outcome by giving fractional advantages to the underdog.

Example: Cloud9 -1.5 maps Asian handicap means Cloud9 must win by at least 2 maps for the bet to pay.

B
Bankroll Management

The practice of allocating a fixed percentage of your total betting funds per wager to avoid ruin during losing streaks.

Example: Betting 2% of your bankroll per match means 10 straight losses only reduces your funds by ~18%, not 20%.

Boost Rocket League

The in-game resource in Rocket League that powers aerial moves and speed — controlling boost pads is a core strategic element.

Example: Teams with superior boost control win more 50/50 challenges; bettors should favor teams strong in aerial rotations.

C
Cash Out

A feature offered by some sportsbooks letting you settle a bet before the match ends, locking in a partial win or cutting losses.

Example: If your pre-match bet on NaVi is looking likely mid-series, cashing out early locks profit but sacrifices the full payout.

Closing Line Value (CLV)

The difference between the odds you bet at and the odds at the start of the match. Consistently beating the closing line is the clearest indicator of long-term betting edge.

Example: Backing T1 at 2.10 before the line closes at 1.85 means you got CLV — the market moved your way.

D
Dead Rubber

A match or map that has no bearing on the outcome of a series or tournament because the result is already decided.

Example: In a best-of-three where one team wins the first two maps, the third map is a dead rubber — some books void bets on it.

Decimal Odds

Odds expressed as a single decimal number representing the total payout per unit wagered, including the stake.

Example: Odds of 2.50 on NAVI return $2.50 for every $1 bet, meaning a $100 bet pays out $250 total ($150 profit).

Draft Priority LoL

The tactical advantage gained by picking champions before the opponent in the League of Legends draft phase.

Example: Teams with strong draft priority on meta carries can build compositions that heavily favor early games, shifting the odds.

E
Economy CS2

The in-game financial system in CS2 where teams earn money by winning rounds, killing opponents, and planting/defusing bombs.

Example: A team winning rounds on an eco (low-buy) round forces the opponent to make suboptimal buys — a sign of momentum bookmakers often undervalue.

Economy Round CS2

A round in CS2 where a team buys minimal equipment due to low funds, usually after losing multiple rounds in a row.

Example: If a team wins an economy round steal, it can shift both the in-game economy and the psychological momentum of the match.

Expected Value (EV)

The mathematical calculation of average outcome across all possible results weighted by probability. Positive EV bets are profitable long-term.

Example: If you estimate T1 has a 55% chance to win but books offer 2.10 (47.6% implied), that is a +EV bet.

F
First Blood

The first kill/elimination of a match or map. Many books offer prop bets on which player or team gets first blood.

Example: In League of Legends, aggressive junglers who invade enemy jungle increase the probability their team scores first blood.

Fractional Odds

A traditional odds format (common in UK) expressing profit relative to stake as a fraction.

Example: Odds of 5/2 on Team Vitality mean you profit $5 for every $2 wagered — equivalent to decimal odds of 3.50.

Futures Bet

A wager placed on a long-term outcome, such as a team winning a tournament before it starts.

Example: Backing a team to win Worlds at +400 before the group stage is a futures bet — value appears when the team is underseeded.

G
Grand Final

The championship match of a tournament, typically played as a best-of-five. Some formats include a winners bracket advantage.

Example: In a double-elimination format, the upper-bracket finalist enters the Grand Final with a 1-0 map lead, shifting the effective odds.

H
Handicap Betting

A bet where the bookmaker applies a virtual head start or deficit to one team to level the playing field.

Example: Placing a -1.5 map handicap on the favorite means they must win 2-0; a +1.5 map handicap on the underdog pays out even if they lose 0-2 by less than 1.5 maps — which is impossible, so it just needs to be considered as a sweep bet.

Head-to-Head (H2H)

The historical match record between two teams. Bettors use H2H data to identify matchup-specific advantages.

Example: NAVI holds a strong H2H record against certain EU rosters on specific maps — historical context a sharp bettor exploits.

I
Implied Probability

The probability of an outcome implied by the odds, calculated by dividing 1 by the decimal odds.

Example: Decimal odds of 2.00 imply a 50% win probability (1/2.00 = 0.50). If you think the team wins 60% of the time, it is a value bet.

In-Play Betting

Placing bets on a match while it is actively in progress, with odds updated in real time based on match events.

Example: Backing a team at live odds after they win the first map is in-play betting — you get worse odds but reduced risk.

J
Juice

See: Vig (vigorish). The commission a sportsbook charges on bets, built into the odds.

Example: A market priced at -110/-110 on both sides has a total implied probability over 100%, with the excess (~4.7%) being the juice.

K
Kill Prop

A proposition bet on the total number of kills by a team or player in a match or individual map.

Example: Betting the over on a Valorant fraggers kill line when their opponent fields a passive, utility-heavy composition.

L
Line Movement

A shift in odds from open to close driven by betting action, sharp money, or new information (roster swaps, player absence).

Example: If a CS2 match opens at -120/-110 and moves to -180/-140, sharp bettors heavily backed the favorite.

Live Betting

See: In-Play Betting.

Example: Esports live betting often offers better value than pre-match because bookmakers adjust more slowly to in-game momentum shifts.

M
Map Handicap

A handicap applied at the map level in a multi-map series. -1.5 means the team must win by 2 maps; +1.5 means they can lose by 1 map and still pay.

Example: Taking the underdog at +1.5 maps in a best-of-three means they only need to avoid a 2-0 sweep to win your bet.

Map Pool

The set of maps available in a competitive rotation for a given esports title. Teams have stronger and weaker maps within their pool.

Example: A team with a limited map pool of three strong maps is predictable — opponents can veto those and force uncomfortable territory.

Map Veto

The pre-match process where teams alternately ban and pick maps from the active pool, determining which maps are played.

Example: Tracking map veto patterns reveals which maps teams avoid — if a team never picks de_inferno, backing the opponent on that map has historical EV.

Moneyline

The simplest bet type — wagering on which team wins the match outright, with no point spread or handicap.

Example: Moneyline bet on Team Liquid to win their match: if they win, you collect; if they lose, you lose the stake.

N
No Action

A bet result where the sportsbook refunds the stake, typically because a match was cancelled or a team forfeited.

Example: If a team no-shows a match due to a visa issue, books typically void all wagers — no action, full refund.

O
Odds Boost

A promotional enhancement by a sportsbook increasing the payout on a specific bet, usually for marketing purposes.

Example: A boosted moneyline on T1 from +150 to +200 temporarily increases expected value — sharp bettors track and exploit these.

Opening Line

The initial odds posted by a sportsbook before any betting action has influenced the market.

Example: Monitoring opening lines lets you catch early value before the market corrects toward efficient pricing.

Over/Under (Total)

A bet on whether a specific statistic will exceed (over) or fall short of (under) a set number, commonly applied to total maps played in a series.

Example: In a Dota 2 best-of-three, betting over 2.5 maps played means you need the series to go to a deciding Game 3.

Overround

The total implied probability across all outcomes exceeding 100%, representing the sportsbook's built-in edge.

Example: A match with both sides priced at 1.83 has an overround of 109% — the 9% excess is the book's theoretical margin.

P
Parlay

A single bet combining multiple selections where all must win for the bet to pay. Higher risk, higher reward.

Example: A three-team parlay on T1, Natus Vincere, and 100 Thieves all winning on the same day amplifies both potential payout and variance.

Pistol Round CS2

The first round of each half in CS2, where both teams start with identical pistol-only budgets — no rifles allowed.

Example: Teams with strong pistol round win rates gain significant economic advantages; tracking this stat helps in CS2 map handicap betting.

Prop Bet (Proposition Bet)

A wager on a specific in-game event or statistic rather than the final match result.

Example: Prop bets in Valorant might include first blood, most kills in a map, or whether a specific map is played in a series.

R
Reverse Line Movement

When odds move against the direction of public betting volume, indicating sharp (professional) money on the opposite side.

Example: If 75% of bets are on Fnatic but the line moves toward the opponent, sharp money is on the other side — a signal to follow.

Roshan Timing Dota 2

The strategic window when Roshan (the most powerful neutral boss in Dota 2) is contestable, often determining team fight timing.

Example: Teams strong in Roshan fights tend to snowball mid-game advantages; this favors over bets on total game duration in Dota 2.

Round Handicap CS2

A handicap applied at the round level within a single CS2 map, rather than at the map level.

Example: Backing a dominant CT-side team -2.5 rounds on a specific map is a round handicap bet — higher risk, higher return than map handicap.

S
Series Price

The overall moneyline odds for a team to win a best-of series (best-of-three or best-of-five), as opposed to individual map prices.

Example: A team might have a weak series price but be a strong value bet at +1.5 map handicap if they typically fight hard even in losses.

Sharp Bettor

A professional or highly skilled bettor whose large wagers consistently move markets. Sportsbooks track and limit sharp action.

Example: When a line moves against public betting percentages, it often signals sharp bettors taking the opposing side.

Side

A bet on one team (or the other) to win a match, as opposed to a total or prop bet.

Example: Taking a side on NaVi moneyline means you win if NaVi wins and lose if they don't — the simplest bet structure.

Spread

The handicap applied to teams to level the perceived playing field. In esports, usually expressed in maps (e.g., -1.5 maps).

Example: Backing a strong team at -1.5 spread means they must win the series 2-0 in a best-of-three for your bet to cash.

Steam Move

A rapid, sharp line movement across multiple books simultaneously, typically triggered by coordinated sharp action.

Example: A steam move on a Dota 2 match from 1.80 to 1.45 within minutes signals high-confidence sharp money — often worth following.

T
Teaser

A parlay variant where the bettor adjusts point spreads or totals in their favor, in exchange for reduced payout odds.

Example: Teasers are uncommon in esports but appear occasionally on kill totals or map counts in best-of-five tournaments.

Total Maps

A bet on the total number of maps played in a series — typically over/under 2.5 for best-of-threes.

Example: In a Valorant best-of-three where teams are closely matched, betting over 2.5 total maps has strong historical frequency.

U
Underdog

The team with a lower implied win probability according to the market, typically assigned positive American odds or odds above 2.00 in decimal format.

Example: An underdog +200 in American odds means a $100 bet pays $200 profit — the market implies roughly a 33% win chance.

V
Value Bet

A bet where your estimated probability of winning exceeds the probability implied by the odds.

Example: If you assess NAVI has a 60% win chance but the book implies 47%, you have a value bet — bet it consistently for long-term profit.

Vig (Vigorish)

The commission a sportsbook charges on wagers, built into the odds by pricing both sides slightly below 100% combined probability.

Example: Standard vig of -110 on both sides of a market means you must win 52.4% of bets to break even, not just 50%.

W
Walk-over (WO)

An automatic match win awarded when the opposing team fails to show up or forfeits.

Example: If a team no-shows due to visa issues, the opponent receives a walk-over win — most books void bets on walk-overs.

Win Probability

An estimate of how likely a team is to win a match, expressed as a percentage. Derived from historical data, form, and market odds.

Example: EdgeRush displays implied win probability on every match preview, calculated from the current decimal odds offered.
