MW Services Limited is registered in Gibraltar (company number 120828) at 5-9 Main Street, Gibraltar GX11 1AA, and runs 4 US sweepstakes brands. Payment processing and support are handled by a separate Delaware corporation, WOWCom Services Inc (company number 5834875), at 108 W. 13th Street Suite 100, Wilmington, DE 19801. The brands are Wow Vegas, launched in 2022 and the best known of them; Rolla, relaunched as a sweepstakes casino in April 2025; CoinsBack; and MetaWin, which opened at metawin.us in November 2025 and is crypto-only, handling both purchases and redemptions in Ethereum, Solana, USDT, USDC, Binance Coin and Ripple rather than conventional payment rails.

Overview

MW Services is a Gibraltar company whose brands sit at very different points on our grading scale, which is unusual for a group this size and is the main reason this page is worth reading before you pick one. The spread is not cosmetic. It tracks a real difference in how the brands have behaved when players could not get paid.

Where the record concentrates

15 cases have been filed with SweepsGuard against this operator, and 12 of the 15 cases are against a single brand, CoinsBack, most of them unpaid withdrawal disputes. 1 ended with money back for a player, recovering $1,750. 14 were refused or ruled unfair. The largest case on record against this group stands at $10,000. Wow Vegas and Rolla, by contrast, account for a single case each.

What the brands share

  • A common operator of record in Gibraltar, with payments and support run through a Delaware company rather than by MW Services directly.
  • A crypto-only sibling in MetaWin, where redemptions settle in cryptocurrency and a disputed balance is harder to trace and harder to reverse than a card or bank payout.

Player guidance

Do not read this operator as one thing. The complaint record here is overwhelmingly a CoinsBack record, and the other brands have not produced anything like the same pattern. If you are playing CoinsBack, redeem early and keep the balance small, because large withdrawals are exactly where the published outcomes turn bad. On MetaWin, remember that a crypto redemption is final in a way a card payment is not.
