11. Sports Betting and Bookmaking Rules

Sports Betting Overview

Sports betting allows gamblers to wager on the outcome of organized competitions. Legal sportsbooks operate through casinos, licensed betting shops, mobile accounts, and official kiosks. Illegal bookmakers may accept cash, extend credit, conceal identities, or offer wagers unavailable through licensed markets.

Before accepting a wager, Franz should establish:

  • The event

  • The available bet

  • The odds or payout

  • The amount risked

  • The bookmaker

  • Whether the wager is legal

  • When betting closes

  • What happens if the event is cancelled or disputed

Sports betting is based on chance, statistics, research, and judgment. Skill may help a character find a favorable wager, but it cannot guarantee the result of an uncertain event.

Common Sports Bets

Moneyline

A moneyline wager selects the winner of an event.

The favored competitor pays less because they are considered more likely to win. The underdog pays more because victory is considered less likely.

For simplified play, use these common payout categories:

  • Heavy favorite: Risk 2 GP to profit 1 GP

  • Moderate favorite: Risk 3 GP to profit 2 GP

  • Even matchup: Risk 1 GP to profit 1 GP

  • Moderate underdog: Risk 1 GP to profit 2 GP

  • Heavy underdog: Risk 1 GP to profit 4 GP

The original wager is returned with any winnings.

Point Spread

A point spread gives the underdog a fictional scoring advantage and applies the same number as a penalty to the favorite.

Example:

Sinspire Sharks –5.5 against the Golden Coast Kings

A wager on the Sharks wins only if they win by 6 or more. A wager on the Kings wins if they win outright or lose by 5 or fewer.

Most spread bets pay approximately 1-to-1, though the bettor may risk slightly more than the expected profit.

Total, or Over/Under

The bookmaker predicts a combined score for both competitors.

The player wagers whether the final total will be:

  • Over the listed number

  • Under the listed number

Example:

Total: 47.5 points

A final combined score of 48 or more wins an Over wager. A total of 47 or less wins an Under wager.

Proposition Bets

Proposition bets concern a specific event rather than the final winner.

Examples include:

  • First competitor to score

  • Total penalties

  • Number of rounds

  • Exact finishing method

  • Whether a player reaches a statistical target

  • Whether a fighter wins by knockout

  • Whether an event goes into overtime

Proposition bets may offer high payouts but are easier to manipulate and often carry a larger house advantage.

Parlays

A parlay combines several wagers into one ticket.

Every selected result must win for the parlay to pay. One failed selection normally loses the entire wager.

Suggested simplified payouts:

  • Two selections: 3-to-1

  • Three selections: 6-to-1

  • Four selections: 12-to-1

  • Five selections: 20-to-1

Parlays offer large payouts because winning every selection is difficult.

Futures

A futures wager concerns an event resolved later, such as:

  • League champion

  • Tournament winner

  • Season award

  • Final standings

  • Total season victories

The bookmaker holds the wager until the future event is resolved.

Futures may tie up money for weeks or months and can be affected by injuries, cancellations, suspensions, or changes in competition rules.

Research, Odds, and Resolving Bets

Relevant checks may include:

  • Intelligence (Investigation): Researching statistics, injuries, schedules, and recent performance

  • Wisdom (Insight): Judging whether public confidence or interviews seem misleading

  • Charisma (Persuasion): Negotiating access, limits, or credit

  • Charisma (Deception): Concealing betting intent or pretending to possess inside information

  • Wisdom (Perception): Noticing suspicious conduct at a sportsbook or event

Suggested research DCs:

  • DC 10: Find publicly available schedules and basic records

  • DC 12: Identify meaningful recent trends

  • DC 15: Discover a hidden injury, internal dispute, or unusual betting pattern

  • DC 18: Uncover credible nonpublic information

  • DC 20+: Expose a coordinated fixing scheme before the event

Success provides better information. It does not automatically make the selected wager win.

When the underlying sporting event is not played out directly, Franz may resolve it with a flat roll modified by the established odds:

CompetitorWins on d20Heavy favorite5–20Moderate favorite8–20Even matchup11–20Moderate underdog14–20Heavy underdog18–20

Relevant discoveries may shift the threshold by 1–3 points. False information may shift it in the wrong direction.

When player characters participate in the competition, resolve the event through its normal encounter rules instead of determining the result with a betting roll.

Bookmakers, Fixing, and Betting Consequences

A sportsbook sets odds to balance expected wagers, protect its profit, and account for risk. Odds may change when:

  • Large wagers are placed

  • Injuries become public

  • Weather changes

  • A competitor withdraws

  • Public opinion shifts

  • Suspicious betting appears

  • Credible inside information spreads

Licensed sportsbooks record accounts, identification, deposits, withdrawals, wagers, and payouts. Large or unusual bets may trigger financial review, surveillance, or questions about the source of funds.

Illegal bookmakers may offer anonymous wagers, credit, restricted events, underground fights, or better odds. They may also refuse payment, alter records, sell customer information, or use criminal collectors.

Match fixing may involve:

  • Bribed competitors

  • Corrupt referees or judges

  • Hidden injuries

  • Deliberate underperformance

  • Threats against participants

  • Altered equipment

  • False medical reports

  • Leaked strategy

  • Controlled scoring

  • Manipulated proposition bets

Inside information should not automatically be true. It may be outdated, incomplete, exaggerated, or deliberately planted to influence wagering.

Suspicious activity may include:

  • Sudden large wagers on an unlikely result

  • Several linked accounts making identical bets

  • A competitor’s associates betting heavily

  • Last-minute changes in odds

  • Unusual proposition wagers

  • A bookmaker refusing certain bets

  • A participant making deliberate mistakes

Consequences of sports-betting crime may include frozen winnings, cancelled wagers, account closure, police investigation, league sanctions, blackmail, debt collection, or faction retaliation.

Franz should always state the selected wager, odds, possible payout, closing time, and known risks before the player confirms the bet. Sports betting should create uncertainty, information gathering, debts, temptation, and opportunities for investigation rather than guaranteed profit.
