DoubleUp and WinX are neck and neck overall, so your choice really comes down to a few details that matter to you. Let’s kick things off with gaming licenses.

Gaming License

WinX has a gaming license from the government of the Union of Comoros, which allows them to operate in many countries, except in some regions where local legislation prohibits their activities. DoubleUp runs license-free for now, relying on on‑chain transparency and provably fair code to win trust.

If you like paperwork and regulatory stamps, WinX comes out ahead. If you care more about open smart contracts than government seals, the difference may feel minor.

Supported Wallets and Crypto

Both Sui casinos connect in seconds to the Slush Wallet but WinX adds MetaMask and Suiet for users who already have accounts on those platforms.

Crypto support tilts the other way. DoubleUp lets you wager with USDC and more than 30 Sui‑based tokens—the bigger basket by far. WinX.io limits play to SUI and 11 SUI-based tokens, including its native WinX token.

Customer Service

Customer support tickets for DoubleUp can be filed on both Telegram and Discord, whereas WinX is only available on Telegram. DoubleUp is the clear winner for players who like real‑time chat channels.

Bonus, Promos, and Contests

DoubleUp rewards active bettors with Doghouse treats and weekly crypto contests. WinX counters with weekly and season‑long contests, plus periodic WinX token airdrops for loyal players.

For now, neither site offers a bonus for first deposits or rakebacks. Instead, they rely on ongoing events to keep bankrolls spinning.

Casino Games

DoubleUp has a larger game library with Craps, Blackjack, Roulette, Range, Plinko, and Limbo, plus live‑dealer Blackjack and Baccarat and third‑party slots. WinX keeps a tighter lineup of Coin Flip, Plinko, Limbo, Roulette, and Dice. Gambling degens will notice that gap and gravitate toward DoubleUp, as it offers more variety.

Raffles and Lottery

Players have more options to spend their crypto on DoubleUp as the platform regularly holds crypto lotteries and online raffles where participants can win luxury watches, cash, and other IRL prizes.

In contrast, WinX pushes its Lootbox, where users can open digital boxes for random prizes—something DoubleUp doesn’t offer natively.

Non-Casino Features

WinX and DoubleUp offer Unihouse Staking, which lets players own part of the “house” and earn a cut from the casino's profits.

But aside from that, DoubleUp is miles ahead of its rival in the extra non-casino offerings. DoubleUp includes a fiat on‑ramp so you can buy SUI or USDC with a debit card. The platform also features a price prediction market where players can bet on short‑term SUI movements. Lastly, DoubleUp has PumpUp, a launchpad that lets you mint and trade your own meme coin without needing to write code.

Nothing comparable exists on WinX, which has chosen to keep its offering focused on gambling and staking rather than branching into token launches or prediction markets.

Each Platform Has Its Merits

DoubleUp.fun feels like the Swiss‑army knife of Sui casinos—many coins, on‑ramp, meme‑coin tools, and a deeper game stack. WinX.io targets players who value a formal license and the perks associated with the WinX token. Both are gambling projects that are evolving fast on Sui, so the best pick will be the one that matches your play style and the crypto already in your wallet.
