Who runs Zombillion?

The Anjouan public register places zombillion.com under Win Top Ltd, licence ALSI-202509029-FI1, issued 16 September 2025 and valid to 15 September 2027 (checked 16 Oct 2026). casino.guru lists Win Top Ltd as operator. On 16 Oct 2026 the domain served a branded regional-block page ("This website isn't available in your region") to both our US checker and a second, non-US connection, showing the contact address support@zombillion.com. The main domain itself shows no footer, cashier or terms. From a UK connection on 16 Oct 2026, the numbered mirror zombillion1.com answered the platform's public API. Its legal pages say "Zombillion.com only accepts customers over 18", which ties the mirror to the registered brand. Those legal pages (terms, footer/licence text, AML, KYC, privacy) name no operator, no licence number, no registration number and no address. The company's country of registration is unclear and not confirmed. Affiliate sources mention a registered office in Mutsamudu, Anjouan (Hamchako) and reg. no. 16122 (affiliate source, unconfirmed).

Zombillion sister sites are related casinos linked through shared ownership or licensing. The available records identify Win Top Ltd as Zombillion’s operator and list the casino under the company’s Anjouan licence.

That distinction matters when comparing casino terms. The review will examine ownership and licensing, available details about related casinos, bonus and account restrictions, and player-safety information, including the concerns reported by Casino Guru.

Quick facts

What sets Zombillion apart

Zombillion is the group's joke brand: a cartoon zombie in a red tracksuit with a trophy for a helmet, spraying champagne across a stage (sistersite.com). It is also the most modest. Its welcome package of 250% up to £4,000 with 200 spins is the smallest on the platform, and its VIP pack only doubles a deposit up to £1,000. casino.guru found it accepts 12 fiat currencies and logs an ignored account-closure request involving £1,600.

Welcome offer & terms (as recorded)

thesistersite.co.uk recorded: thesistersite (Aug 2026): zombie theme; 250% up to £4,000 + 200 FS; 140% USDT crypto offer. sistersite.com recorded: cartoon zombie in red tracksuit mascot; 250% up to £4,000 + 200 FS; VIP pack only 100% up to £1,000; smallest bonuses in group (affiliate source, unconfirmed). Confirmed on-site (terms via zombillion1.com, 16 Oct 2026): wagering is calculated as (deposit + bonus) × the offer's coefficient, the maximum bet with a bonus is €5, only one bonus can be active at a time, and a pending withdrawal blocks new bonuses. The Wheel of Gods prize rules set 35x on bonus money and free-spin winnings, with conversion capped at 5x the bonus. The general terms do not give the coefficient for each welcome offer, so any affiliate claim of "bonus-only" wagering conflicts with the terms' formula. These are offers recorded by third parties, not offers we have checked. Group-wide terms recorded by reviewers: 35–40x wagering, a £5/€5 maximum bet and cash-outs capped at 5–10x the bonus. casino.guru rates the terms: Unfair, 4 issues (short KYC deadline, bonus hunting, low-risk play x2).

Games & providers

casino.guru counts 154 game studios, including NetEnt, Nolimit City, Playtech, Evolution, Pragmatic Play. We publish no RTP figures.

Our verdict

casino.guru gives Zombillion a Safety Index of 4.7 Low. We would not recommend it.

Payments

casino.guru lists 18 incl. Skrill, Visa, Mastercard, bank transfer, Santander, Apple Pay, Google Pay, Revolut, Wise, 9 crypto. Withdrawal limits: EUR 500/day, 2,000/week, 7,000/month; no win limit. Cashier details that casinobuddies or sistersite.com published are included in the offer notes above. On-site (UK market, via zombillion1.com, 16 Oct 2026): 19 cashier methods. Card withdrawals run £50–£2,500, bank transfer £50–£4,000 and USDT TRC20 up to £10,000 per transaction. Deposits start at £20. The terms promise processing within three business days plus bank time, every deposit must be turned over 3x before withdrawal, and wins above the monthly limit are paid in monthly instalments. The terms say daily, weekly and monthly limits are "established in separate policies", which we did not find published.

Safety & complaints

casino.guru complaint log: 4 (1 unresolved, 2 resolved, 1 rejected); ignored account-closure request £1,600; delayed payouts £650, £500. Other notes: loyalty: personal manager, cashback, rakeback; zombie theme (thesistersite). The terms (via zombillion1.com, 16 Oct 2026) list the United Kingdom among restricted countries, together with the USA, the Netherlands, Sweden, Russia, Ukraine, Cyprus, Malta, Romania, Israel and others, and warn that withdrawals cannot be guaranteed for players who breach that rule. This settles the conflict with an affiliate list that left the UK out.

Customer support

Email: support@zombillion.com (shown on the site's regional-block page, 16 Oct 2026). casino.guru: 24/7 live chat, mostly after registration, rated Average (instant, 12 Apr 2026). The terms (via zombillion1.com) give block@support-zombillion.com and support@support-zombillion.com (the block@ address is for self-exclusion).

Responsible gambling at Zombillion

casino.guru rates responsible-gambling tools as: Limited. The site's responsible-gambling page (via mirror, 16 Oct 2026) offers voluntary self-exclusion for a set period (lifting it early is at the casino's discretion) and stake limits that take effect 24 hours after a change. No deposit-limit or reality-check tool is described. None of the Win Top brands is part of GAMSTOP. Help: /responsible-gambling/.
