Duel review

The official Sports Betting Rules at /policies/sports-betting-rules were marked Updated: 01.06.2026. The document rendered approximately 2,000 non-empty lines and is much more detailed than the earlier summary.

Live sportsbook rendering status

The authenticated /sports route loaded the Duel header, chat and footer, plus a Sports | Duel document title and a sports description. The actual sportsbook region was a #betby container approximately 1,904 px wide and 3,845 px high in the desktop inspection. It contained one empty renderer child and no readable events, leagues, market buttons, odds, betslip, sportsbook links or sportsbook iframe.

This was reproducible after a reload and an additional wait. The page loaded https://duel.sptpub.com/bt-renderer.min.js and Duel's sports route asset. Console output reported the BT renderer build time as 28.07.2026 23:23:56, successful authentication, live and prematch polling, a top-events request, and a Main content loaded message. Despite those integration messages, no sportsbook content became visible or readable in the page DOM. No explicit JavaScript exception naming the root cause appeared.

The honest conclusion is therefore narrow: the sportsbook renderer did not expose usable betting content in this authenticated Chrome session on 2 August 2026. It is not valid to invent or infer the current sports menu, competitions, individual events, live status, markets, odds, odds format, betslip controls, stake presets, Cash Out availability, limits or jurisdictional availability from the rules alone.

Bet types defined in the rules

• Single: one selected outcome. The rules describe the return as stake multiplied by the accepted odds if the selection wins.
• Combo / Parlay / Accumulator: two or more independent selections; every selection must win. The combined odds are the product of the component odds.
• System: a collection of multiple combinations, with the same stake applied to each combination. It can return something even when not every selection wins, depending on the system and results.

The rules state that payouts are rounded to the nearest two decimal places.

Cash Out, Bet Builder and Early Payout

• Cash Out: may settle a bet before the event ends at the currently offered terms. It can be available before an event or in play. The player may accept or decline the displayed offer, but the provider may change, suspend or withdraw the offer.
• Bet Builder: combines multiple markets from the same event. Every included selection must be correct. Availability is discretionary. If one selection is void, that selection is removed and the remaining selections stand. Bet Builders may be combined with Combos, Systems, other Bet Builders or standard selections where the interface permits it.
• Early Payout: applies only where the event or market carries the relevant offer and the predefined condition occurs. It can settle a qualifying bet before the final result. The rules say it may apply to Singles, Combos, Systems, Bet Builders, and certain bonus contexts. In a multiple, the qualifying leg may settle early while the remaining legs continue. Duel reserves rights to change, withdraw, reject, void or correct the offer, including after VAR-related changes.

These are rulebook capabilities, not proof that the controls were available on a particular event during this inspection.

Settlement, postponements, interruptions and voids

• Fixed odds are defined as the odds accepted when the bet is placed.
• The operator may apply general or individual stake, payout, winnings and odds limits; the rulebook does not publish one universal number for all users and markets.
• An accepted bet cannot be reversed by the user merely because the user changed their mind.
• The Sportsbook may accept or reject a proposed stake.
• A postponed event with no updated information within 12 hours of the original start time is generally void. If it is rescheduled within 12 hours and starts within 48 hours, bets generally stand, subject to sport-specific exceptions.
• If a started event is interrupted and not completed within 48 hours, unsettled bets are generally void. Exceptions include completed periods, already decided markets, long-duration events and sport-specific rules.
• A void selection is refunded and is treated at odds 1.00 inside an affected multiple, subject to the detailed market rules.
• Live scores, timers, statistics and streams are informational and may be delayed or inaccurate; settlement follows the official result and applicable rules.
• Bots, automated betting and multi-account techniques intended to circumvent limits are prohibited.
• The settlement hierarchy is Market Rules over Sport Rules over General Rules. Event-specific market wording remains decisive.

Sports and event families covered

The rulebook includes soccer, tennis, basketball, American football, ice hockey, baseball, handball, volleyball, beach volleyball, futsal, badminton, rugby union, rugby league, rugby sevens, darts, snooker, table tennis, bowls, cricket, squash, Australian rules football, boxing, MMA, golf, motorcycle racing, athletics, winter sports, Formula 1, chess, kabaddi and cycling. Separate material covers esports, horse racing, greyhound racing, harness racing and predictions.

The document also defines common soccer markets such as 1X2 and Double Chance, but the list in the rulebook must not be represented as the exact set currently offered in the broken renderer.

Sportsbook data not captured

The following remain unknown for the inspected session: visible sports and leagues; pre-match and live event counts; current fixtures; odds and odds format; market depth; maximum and minimum stake; maximum payout; betslip behaviour; current promotions; actual Cash Out / Bet Builder / Early Payout tags; live-stream availability; geographic restrictions applied by the renderer; and whether the empty state was account-, network-, extension-, region- or provider-specific.

The sportsbook provides live and upcoming fixed-odds betting, live scores, event pages, a betslip, Quick Bet and odds settings. European odds were the displayed default.

The live menu exposed 37 categories:

Soccer, Basketball, Tennis, Counter-Strike, Dota 2, Valorant, Baseball, Ice Hockey, Cricket, Table Tennis, Badminton, Boxing, eSoccer, eBasketball, Handball, Volleyball, Golf, eHorse Racing, eSoccer: Volta, eSoccer: Penalty, eFighting, eTennis, eBasketball: Blitz, Australian Football, eSoccer: X-Battle FC, eCricket, King of Glory, Rugby League, Sumo, FC 26, Kabaddi, NBA 2K26, Teqball, Cricket 24, Footvolley, eCricket: X-Battle Bats and eVaquejada.

The upcoming menu exposed 47 categories, adding or substituting League of Legends, American Football, Darts, Rugby Union, Mixed Martial Arts, Rainbow Six, Chess, Futsal, Arena of Valor, Mobile Legends, Water Polo, Beach Soccer, Wrestling, StarCraft 2, Call of Duty, Crossfire and Pro Wrestling.

Coverage is event-dependent and the counts describe the visible category menus, not a permanent guarantee that every sport always has markets.

Betting formats and settlement

The sportsbook rules cover:

• live and pre-match fixed odds;
• single selections and combination bets;
• dependent selections through a specific Bet Builder where offered;
• match-result, totals, handicaps, both-teams-to-score, odd/even and interval markets;
• outrights, top-finish markets, head-to-heads and triple-heads;
• next-event, race-to-X and chronological-event markets;
• sport-specific rules for soccer, tennis, basketball, American football, ice hockey, baseball, handball, volleyball, cricket, combat sports, golf, motorsport and others;
• game-specific esports rules;
• horse, greyhound and harness racing;
• prediction markets covering politics, arts, entertainment, science and sporting milestones.

Limits can differ by user, sport, league and market and can be changed by the operator. Incorrect odds, technical errors, abandoned events, non-runners and late bets can be voided under the rules. A void bet is returned at odds of 1.00. Official source data is used for settlement; displayed live scores and streams are informational and may be delayed.

Cash Out, Bet Builder and system bets

Cash Out can be offered on both pre-match and live bets. Accepting the displayed offer settles the bet immediately on those terms. Duel's sportsbook provider can change, suspend or remove a Cash Out quote at any time, so an earlier quote is not guaranteed to remain available.

Bet Builder combines multiple markets from the same event. Every included selection must win. Related outcomes cannot be placed together in a normal combo unless the sportsbook explicitly permits the combination through Bet Builder.

The rules define single, combo and system bets. A combo pays stake x combined odds when every leg wins. Named systems are also documented:

Calculated winnings with more than two decimal places may be rounded to two decimals using standard mathematical rounding. The rules do not publish a universal sportsbook maximum win. Limits can apply per user, selection, bet, event or market and may change.

No permanent Free Bet or Odds Boost entitlement is defined in the general sportsbook rules. Their absence from that document does not prevent a temporary campaign, but players should not list them as standing account benefits without an active offer.

Postponements, interruptions and disputed results

• If an event is officially cancelled before it starts, its bets are void.
• If no rescheduling update appears within 12 hours of the original start time, affected bets are void unless a sport-specific rule overrides the general rule.
• If the event is rescheduled within 12 hours and starts within 48 hours of the original time, bets stand.
• If a started event is interrupted, postponed or suspended and is not completed within 48 hours of its official start, bets are generally void.
• Completed periods and outcomes that were already unconditionally determined can still be settled.
• Events that normally last more than 30 hours and sport-specific exceptions can follow different rules.
• A void bet returns the stake through settlement at odds of 1.00.
• Dead heats divide the relevant stake by the number of tied competitors before full odds are applied to the winning portion.
• Outrights use the first official result at the podium, medal ceremony or award announcement; later appeals or disqualifications are normally ignored.
• Live scoreboards and streams can be delayed or inaccurate and are not the settlement authority.

The rules say reputable data sources are used for settlement. The exact source may be disclosed on reasonable request at the operator's discretion during a dispute.
