On this page
bet365 is one of the best-known names in UK online gambling, built primarily around sports betting with a casino section attached. Mythoswin takes a different shape: a casino-first lobby of 5,000+ games alongside a sportsbook covering 30+ sports. This page compares the two on the things that usually matter most when choosing where to play.
Games and sportsbook
bet365 is widely known for the depth and breadth of its sportsbook markets, alongside a large casino catalogue. Mythoswin’s lobby covers 4,200+ slots from studios including Novomatic, Hacksaw Gaming, Betsoft, Blueprint Gaming and Skywind, plus 300+ live dealer tables and game shows and a sportsbook spanning 30+ sports. See the full range on the Mythoswin games hub, including the dedicated slots and sportsbook pages.

Welcome bonuses
Mythoswin’s casino welcome bonus is 100% up to £500 + 150 Free Spins on Book of Ra Deluxe, with a £20 minimum qualifying deposit and 10x wagering on both the bonus and free-spin winnings. On the sports side, new customers can instead choose Bet £10, Get £30 in Free Bets (3 × £10), with a qualifying bet of £10 or more at odds of 1/2 or bigger. You pick one welcome offer, casino or sportsbook, not both — full detail is on the promotions hub and the wagering requirements page.
bet365 is well known for running its own sportsbook and casino welcome promotions, but this guide does not quote specific bet365 figures, since those change and only bet365’s own site can confirm what is currently live.

Both Mythoswin and bet365 operate under UK licensing rules, so neither accepts credit cards or cryptocurrency — both are banned for UK gambling. Mythoswin supports Visa and Mastercard debit, Apple Pay, Google Pay, PayPal, Skrill, Neteller, Revolut, open-banking Rapid Transfer, Paysafecard for deposits, and bank transfer, with a £10 minimum deposit on most methods. Withdrawals are approved within 3 hours, 24/7, for verified accounts, subject to £5,000 daily and £25,000 monthly limits. See the payments hub and withdrawals guide for the full breakdown. bet365 supports a broad set of UK payment methods too; check its own site for current minimums and processing times.
Jackpots and promotions beyond the welcome offer
Mythoswin runs the Olympus Jackpots network — four tiers (Hermes, Athena, Apollo and Zeus) that can trigger on selected slots during ordinary real-money play, with Zeus seeded at £50,000. It also runs the weekly Labours of Hercules slot tournament and the Spartan Acca Boost for football accumulators of 5+ legs. Details are on the jackpots page. bet365 runs its own range of ongoing promotions and odds boosts, which this guide does not detail here.
Support and account security
Mythoswin offers 24/7 live chat with an average first reply under 2 minutes, email support with replies within 24 hours through the Help Centre contact form, and a library of Help Centre articles. Account security includes TLS 1.3 encryption, PCI-DSS payment processing, optional two-factor authentication and passkey or fingerprint login on compatible mobile browsers. See support and the account hub for more. bet365’s support channels and security measures are set out on its own site.
Registration and verification
Both operators work under UK Gambling Commission rules, so both must verify your age and identity before any deposit or play. Mythoswin’s sign-up asks for email, password, full name, date of birth, UK address, and mobile number, then runs automatic electronic checks that usually complete within minutes, with manual review in 24–48 hours if documents are requested. See the registration guide for the full walkthrough, including which documents to have ready. bet365’s own registration and verification process follows the same UK regulatory requirements, set out on its own site.
Which one suits you
If you want a long-standing, very large sportsbook alongside a casino, bet365’s scale may appeal. If you want a clearly stated casino welcome bonus, a wide slots and live-casino lobby, and withdrawals approved within 3 hours, Mythoswin is worth a look. Either way, read the operator’s own current terms before signing up, and gamble 18+ and within your limits — see BeGambleAware.org for free, confidential support.
