Duel UK: $2m Monthly Leaderboards, Original Games & Sports

Duel serves UK players with 11 proprietary games, 31 sports, 25 esports titles and a sportsbook built around Cash Out, Bet Builder and Early Payout. Our monthly leaderboard carries $2m in prizes, while our daily leaderboard offers $25k for slots and live games. We operate through Immortal Snail LLC under a licence issued by the Government of the Autonomous Island of Anjouan in the Union of Comoros.

Our site covers the games, sports markets, betting features, leaderboards and support options available through Duel. It is intended for adults aged 18+ and is independent of the operator, so our wording separates the features we can verify from the practical decisions you need to make before using your account.

Our sportsbook bonus and its core rules

Duel’s sportsbook includes a selection-based Comboboost, although the available sportsbook rewards are structured differently from a welcome deposit package. The bonus applies only to eligible market selections priced at 1.50 odds or higher. Cash-out bets and system bets do not contribute towards its wagering requirements.

The Comboboost multiplier rises with the number of selections. Two selections produce a 1.01 multiplier, rising through the range as more legs are added, before reaching 2 for a 20-selection bet.

Choose only selections at 1.50 odds or above, and check whether a cash-out or system structure affects the bonus before placing the bet.

Sportsbook feature	How it works
Comboboost minimum odds	1.50
Two-selection multiplier	1.01
Ten-selection multiplier	1.2
Twenty-selection multiplier	2
Cash-out bets	Not eligible
System bets	Excluded from bonus wagering

T&Cs apply. 18+. New customers only. Please gamble responsibly (BeGambleAware.org).

Sports and esports markets at Duel

Duel covers 31 sports, giving the sportsbook room for major leagues, individual disciplines and less familiar markets without relying on the same handful of events. The selection ranges from football and tennis to darts, snooker, golf, Formula 1 and winter sports.

Our sports catalogue includes:

• Soccer, tennis, basketball, American football and ice hockey for major team and individual events.
• Baseball, handball, volleyball, badminton, rugby, cricket and boxing across domestic and international schedules.
• Golf, Formula 1, motorsport, cycling, athletics and winter disciplines for specialist markets.
• Snooker, darts, table tennis, bowls, squash, chess, greyhound and horse racing.

The same sportsbook carries 25 esports titles, from established team games to battle-royale formats. Dota 2, Counter-Strike 2, League of Legends and Valorant sit alongside FC 26, NBA 2K26, Tekken, Street Fighter and Rocket League.

Our esports solutions add 24 virtual competitions. These include eSoccer, eBasketball, eFighting, eCricket, eShooter, eTennis, eBoxing and eMMA, with specialist variants such as Volta, Penalty, Blitz and X-Battle.

Our games and sports betting tools

Duel combines an 11-game original suite with a wide sportsbook, including virtual sports, esports and predictions. Our original games cover dice, blackjack, plinko, crash, mines, keno, video poker, rock paper scissors and limbo, alongside a live castle roulette title.

Duel’s betting features

Duel gives sportsbook users Cash Out on both pre-match and live bets. Bet Builder can combine selections and can be used within Combo or System bets, while Early Payout settles qualifying bets as winners once predefined conditions are met.

Our Bore Draw market refunds qualifying bets when the selected football match finishes 0–0. The refund applies only where the market conditions are met, so the match selection and settlement rules remain part of the bet itself.

Three other sportsbook mechanics give you different ways to manage a stake. A free bet credits net winnings without returning the original stake, whereas freemoney credits both the stake and winnings. Bet no risk operates like a standard bet but refunds the stake if it loses.

Feature	Practical result
Cash Out	Available for pre-match and live bets
Bet Builder	Can be combined with Combo or System bets
Early Payout	Settles as a winner when predefined conditions are met
Bore Draw	Refunds qualifying bets after a 0–0 football result
Free bet	Net winnings are credited; the stake is not returned
Freemoney	Both the stake and winnings are credited
Bet no risk	The stake is refunded if the bet loses

The mechanics behind our Comboboost

The Comboboost is determined by the number of qualifying selections, so its sequence is easier to follow than a standard deposit bonus. Our sportsbook applies the following order:

1. Build the selection using market choices priced at 1.50 odds or higher.
2. Exclude cash-out bets and system bets from the qualifying selections.
3. Use the number of eligible selections to determine the multiplier.
4. Apply the resulting multiplier to the bonus calculation.

The multiplier moves from 1.01 for two selections to 1.05 for five, 1.2 for ten, 1.5 for sixteen and 2 for twenty. Duel also gives separate multipliers to 3, 4, 6, 7, 8, 9 and selections above ten.

Duel Originals and our leaderboard prizes

Duel Originals is our proprietary suite of 11 games, and we describe each title as having a 100% RTP. The range includes low-variance choices such as Plinko and Keno, decision-based games such as Dice and Rock Paper Scissors, and crash-style games including Crash and Limbo.

The same product group includes Blackjack, Beef, Mines, Video Poker and Castle Roulette, which is identified as a live game. These 11 titles sit within our broader gaming offer, where our leaderboards connect slots and live games to $2m in monthly prizes and $25k in daily prizes.

The leaderboard structure adds a competitive route through Duel without changing the underlying game rules. Each entry depends on the relevant slots or live-game activity, while the prize pools give both monthly and daily leaderboard schedules their own scale.

Our licence and operating details

Duel is operated by Immortal Snail LLC, registered under number L22982 at Arthur Evelyn Building, Suite 5, Main Street, Charletown, Nevis, West Indies. Our licence is issued by the Government of the Autonomous Island of Anjouan in the Union of Comoros and carries the number ALSI-202411026-FI1.

The licence jurisdiction is Anjouan rather than the UK Gambling Commission, so the regulatory label attached to Duel is not the same as a UKGC licence. The operator’s own contact route is the email address [email protected].

Our account access is restricted to people aged 18+. Players are responsible for their own decisions and should use only the account registered to them.

Getting help with your Duel account

Duel’s confirmed support route is email, and account-specific questions should be directed to the customer support team through the operator’s address. This covers help with registration, deposits, withdrawals, sportsbook bets, original games, verification and technical problems that affect access to your account.

Before writing, have the email address attached to your account and any reference number shown on screen ready. The approximate date of the issue and a short description of what happened can help support identify the relevant step, especially for a deposit, a bet or a game round.

Questions to include in a support message

A useful message gives the support team enough information to follow the issue without turning the email into a general account history.

• The email address used to register your Duel account.
• The approximate date and time when the problem occurred.
• The relevant transaction, bet or game reference shown on screen.
• A clear description of the outcome you need help with.

Account issues that require a clear record

For a payment or withdrawal enquiry, record what happened without adding assumptions about a fee, limit or approval. For a sportsbook issue, include the market, selections and whether Cash Out or Early Payout applied. For an original game, identify the title and the round involved.

Our support team can also handle requests connected with responsible gambling. Duel provides a seven-day cooling-off period, and self-exclusion locks an account for at least six months while stopping promotional material.

Responsible gambling requests

A self-exclusion request should be made through the same customer support route. Once the account is locked, promotional messages stop as part of the exclusion process. If you want a shorter pause, a seven-day cooling-off period is available through the responsible gambling support team.

The minimum account age is 18+. A shared device can create an unwanted access risk, particularly where children or other adults use the same browser or mobile equipment.

What distinguishes Duel

Our original suite claims a 100% RTP across 11 games, giving Duel a tightly defined in-house collection rather than a catalogue built entirely around third-party studios. The sportsbook supplies a second point of distinction through its mix of traditional sports, 25 esports titles, 24 virtual sports and betting tools such as Bet Builder and Early Payout.

The scale of our leaderboards is also concrete. A $2m monthly pool sits alongside a $25k daily prize schedule for slots and live games, so the same gaming section carries both long-running and shorter competitive cycles.

These features make Duel particularly relevant to players who want proprietary games, a large sports market and esports in the same service. The Comboboost rules still need checking before a bet, particularly the minimum odds and the exclusion of cash-out and system bets.

Our assessment of Duel for UK players

Duel combines an 11-game original suite with one of the broadest sportsbook structures in our review material: 31 sports, 25 esports titles and 24 virtual competitions. Its betting tools include Cash Out, Bet Builder, Early Payout and Bore Draw, giving you several distinct ways to place and settle a sports bet.

The strongest figures are attached to our leaderboards, with $2m available monthly and $25k daily. The 100% RTP statement applies to our named Duel Originals range and should be read as the operator’s stated game configuration.

The main practical point to check is the sportsbook bonus structure. Comboboost eligibility depends on minimum odds, and the excluded bet types can materially affect whether a qualifying selection contributes. Our original games, sports coverage and leaderboard schedules provide a clear basis for deciding whether Duel matches your priorities.

Responsible gambling at Duel

Gambling should remain entertainment rather than a task or a source of income. Our account access is for adults aged 18+, and Duel provides a seven-day cooling-off period alongside self-exclusion lasting at least six months and stopping promotional messages.

Useful UK support includes GamCare, the National Gambling Helpline on 0808 8020 133 and BeGambleAware.org. The National Gambling Helpline is free and available 24/7.

You can also use GamStop for free national self-exclusion across licensed sites. Gordon Moody provides residential and online treatment support, while Gamban and BetBlocker can block gambling sites across supported devices.

For shared devices, parental-control software such as Net Nanny or Qustodio can help prevent access by a minor. Keep your account credentials private and step away if betting becomes difficult to control.
