Our verdict on DoubleUp
5.2/10DoubleUp suits crypto users on Sui who want a casino mixing in-house games, a large third-party catalogue and a price prediction game. Its main strength is that variety. The main caveat is the lack of published detail: public sources name no licence, no KYC policy, no audits and no fee data, and on-chain TVL is small. Verify those points on the official site, confirm that gambling is legal where you live, and start small if you proceed.

What is DoubleUp?
DoubleUp is a blockchain-based casino platform on the Sui network. DefiLlama lists it as a DeFi gaming platform in its Luck Games category, with the UP token and a listing date of June 2024.
The project's X account says the doubleup.io site is live with six DoubleUp Originals, more than 3,000 Pragmatic and Evolution games and a crypto trading prediction game. Documentation describes that last game as a way to speculate on whether a crypto asset finishes over or under a set price.
On-chain activity looks modest, with TVL around $35,000 and little change over the past week. Its homepage available to us is minimal, so key details such as licence, KYC, accepted coins and bonuses cannot be confirmed here.
How DoubleUp works
DoubleUp is a crypto casino on the Sui network. Players deposit crypto, choose a game and stake against the house, as at any online casino. The platform combines its own games with a large third-party catalogue.
The prediction game works differently. Players bet on whether a chosen crypto asset's price will be over or under a set level when the round ends. The payout depends on the outcome and the rules of that game.
Third-party profiles describe smart contracts and provably fair design. The project does not detail how outcomes are generated or verified, so fairness claims should be checked against the project's own documentation.

Pros and cons
What we like
- Mixes in-house originals with a large third-party game catalogue.
- Includes a crypto price prediction game for users who prefer market-style betting.
- Runs on Sui, which suits users already holding assets on that network.
- Third-party descriptions emphasise smart contracts and provably fair design.
- Has a visible public presence, including an active X account and public documentation.
Watch out for
- No gambling licence is stated, so the regulatory position is unclear.
- KYC requirements are not published publicly, so users cannot tell what identity checks apply.
- DefiLlama lists no audits for the project.
- TVL is small at roughly $35,000, which suggests a limited on-chain footprint.
- The UP token appears to trade thinly, and third-party price figures in public reporting conflict.
- Its homepage available for review is minimal, so deposit coins, limits and bonuses cannot be confirmed.
DoubleUp fees
DoubleUp's fees are not published publicly we reviewed. That includes house edge on individual games, deposit and withdrawal charges and any prediction-game fees.
Users should check each game's rules and the cashier or wallet screen for house edge, payout rules and network fees before staking. Sui transaction costs would apply to on-chain activity.
Is DoubleUp safe?
No audits are listed on DefiLlama, and public sources name no gambling licence or regulator. That leaves counterparty and smart-contract risk without independent verification. A security scanner reports no malware or phishing threats at the site, but that does not speak to fairness, solvency or legal standing.
Check the site's own terms for licensing, KYC, withdrawal rules and dispute handling before depositing. Online gambling is restricted in many places, so confirm it is legal where you live. Play is for adults only (18+), and you should set limits and stop if gambling stops being fun.
6 steps
How to get started with DoubleUp
- 1
Confirm that online gambling is legal where you live and that you are 18 or older.
- 2
Visit the official DoubleUp site and read the terms, licensing information and any KYC policy.
- 3
Set up a Sui-compatible wallet if the site uses wallet connection, and check which deposit assets it accepts.
- 4
Start with a small deposit and try the game rules and payout details before staking more.
- 5
Set deposit and loss limits before you play, and withdraw winnings you do not plan to re-stake.
- 6
Treat the UP token as a separate, speculative decision, not as part of playing.
Who DoubleUp is for
DoubleUp is for adults in jurisdictions where online gambling is legal who already use Sui and want crypto-native casino games plus an over/under price prediction game. It is a poor fit for anyone who needs a clearly stated licence, audited contracts or confirmed no-KYC terms.
