Current ZERO Game Availability
The live Originals catalogue reviewed on July 30, 2026 contained 31 MetaWin Originals. Page two explicitly listed four games at 100% RTP:
| Game | Catalogue RTP | Current Audit Status |
|---|---|---|
| Mines ZERO | 100% | |
| Dragon Tower ZERO | 100% | |
| Limbo ZERO | 100% | |
| Roulette Zero | 100% | |
| Dice ZERO | Indexed content says 100% |
The $25,000 Rule Applies Across ZERO Originals
MetaWin’s current Terms state that the maximum win on any Zero House Edge Original is limited to the equivalent of $25,000 per individual game or round.
The Mines ZERO page describes the same number as a “maximum potential payout.” This review therefore uses the stricter interpretation: $25,000 as the total payable amount unless the live game rules explicitly state otherwise.
Cap-Safe Stake Formula
| Target Multiplier | Maximum Cap-Safe Stake | Example Above Threshold | Cap Result |
|---|---|---|---|
| 10x | $2,500 | Usually above current game stake limits | Cap unlikely at ordinary stakes |
| 100x | $250 | $300 | $30,000 fair payout becomes $25,000 |
| 250x | $100 | $100 is exactly cap-safe | No truncation |
| 1,000x | $25 | $100 | $100,000 fair payout becomes $25,000 |
| 10,000x | $2.50 | $3 | $30,000 fair payout becomes $25,000 |
How the Cap Changes Effective RTP
For a fair fixed-target binary bet with win probability p and fair gross multiplier 1/p:
If the target multiplier is 10,000x, the fair win probability is 0.01%. The examples below assume that the game allows those stake and multiplier combinations.
| Stake | Fair Payout | Paid Under Cap | Actual Multiplier | Cap-Adjusted RTP |
|---|---|---|---|---|
| $1 | $10,000 | $10,000 | 10,000x | 100% |
| $2.50 | $25,000 | $25,000 | 10,000x | 100% |
| $3 | $30,000 | $25,000 | 8,333.33x | 83.33% |
| $5 | $50,000 | $25,000 | 5,000x | 50% |
| $10 | $100,000 | $25,000 | 2,500x | 25% |
These figures apply to that specific fixed-target configuration, not automatically to the whole game.
Mines ZERO: Strongest Current Public Example
Mines ZERO currently provides the clearest public data:
- 100% RTP and 0% house edge;
- 5×5 grid with 1–24 mines;
- $0.10 minimum bet;
- $100 maximum bet;
- $25,000 maximum potential payout;
- provably fair controls.
At the maximum $100 stake, any target above 250x exceeds the cap.
| $100 Target | Fair Uncapped Payout | Capped Payout | Configuration RTP |
|---|---|---|---|
| 100x | $10,000 | $10,000 | 100% |
| 250x | $25,000 | $25,000 | 100% |
| 500x | $50,000 | $25,000 | 50% |
| 1,000x | $100,000 | $25,000 | 25% |
For a multi-outcome game, total cap-adjusted RTP must be calculated by replacing every affected payout with its capped value and summing probability × actual payout.
Standard Originals Are Not ZERO Games
| Standard Original | Current Catalogue RTP | ZERO Version Confirmed? |
|---|---|---|
| MetaWin Baccarat | 99.5% | No current ZERO listing found |
| MetaWin Blackjack | 99.5% | No current ZERO listing found |
| MetaWin Mines | 98% | Mines ZERO listed at 100% |
| Limbo | 98% | Limbo ZERO listed at 100% |
| Dragon Tower | 98% | Dragon Tower ZERO listed at 100% |
| MetaWin Roulette | 97.3% | Roulette Zero listed at 100% |
| MetaWin Crash | 98% | No current Crash ZERO listing found |
Provably Fair Evidence
MetaWin says all Originals combine a hidden server seed, player-set client seed and nonce. The server seed is hashed before play and revealed after the round for verification.
| Question | Provably Fair Check | Separate Audit |
|---|---|---|
| Was the result consistent with disclosed seeds? | Yes, with the complete algorithm. | Confirm the exact game version. |
| Is the displayed RTP 100%? | No. | Audit probabilities and gross payouts. |
| Did the $25K cap alter settlement? | No. | Compare uncapped and paid amounts. |
| Is the platform safe or solvent? | No. | Licence, Terms, KYC and withdrawal review. |
Use the Provably Fair Checker only when its selected algorithm matches the MetaWin game being tested.
Operator, Licence and KYC Risk
The current MetaWin footer states that the site is owned and operated by Rivolo Limited in Nevis and operates under Anjouan licence ALSI-202602025-FI1. These details replace older operator and licence information found in previous reviews.
| Risk Area | Current Reading | Review Position |
|---|---|---|
| Operator transparency | Rivolo Limited, address and company number are published. | |
| Licence | Anjouan licence number is displayed sitewide. | |
| KYC and AML | Terms permit temporary holds during verification. | |
| Web3 access | Wallet integration adds signing and wallet-security risks. | |
| Consumer recourse | Offshore regulator rather than a mature high-protection market. |
MetaWin vs Duel and Gamdom
| Platform | Primary Fair-Return Model | Main Limitation | Core Audit |
|---|---|---|---|
| MetaWin | Named native 100% RTP ZERO games | $25,000 maximum win | Cap-adjusted payout and full paytable |
| Duel | Allowance-based instant return and game-specific edge states | Eligible volume and complex-game exceptions | Tracker, displayed edge and completed result |
| Gamdom | Around 99% base RTP plus rewards and instant returns | Undisclosed reward formula | Actual rewards divided by eligible turnover |
How to Audit a MetaWin ZERO Bet
- Confirm the exact game: verify that the live lobby labels it as ZERO and 100% RTP.
- Record the stake: use the amount actually debited.
- Record the target multiplier: use the chosen cashout state.
- Calculate uncapped payout: stake × multiplier.
- Apply the $25,000 ceiling: use the lower amount.
- Recalculate effective RTP: replace capped payouts in the distribution.
- Verify the result separately: use the exact seed and game algorithm.
- Test account flow: complete a small withdrawal before increasing exposure.

Frequently Asked Questions
Which MetaWin ZERO games are currently confirmed?
The current catalogue lists Mines ZERO, Dragon Tower ZERO, Limbo ZERO and Roulette Zero at 100% RTP.
Is Dice ZERO still available?
Indexed content still describes Dice ZERO with 100% RTP, 10,000x and a $25,000 cap, but its direct page returned “Game Not Found” during review. Check the live lobby.
Does the $25,000 cap apply to every ZERO game?
MetaWin’s Terms state that the maximum win on any Zero House Edge Original is $25,000 per individual game or round.
How do I avoid the cap?
Keep stake × target multiplier at or below $25,000. The cap-safe stake equals $25,000 divided by the target multiplier.
Can the cap reduce RTP below 100%?
Yes. Once the fair payout exceeds the cap, the actual multiplier becomes smaller than the fair multiplier.
Are all MetaWin Originals provably fair?
MetaWin states that all Originals use server seed, client seed and nonce verification. This does not mean every Original has 100% RTP.
Who currently operates MetaWin?
The current site footer identifies Rivolo Limited and Anjouan licence ALSI-202602025-FI1.
Is MetaWin no-KYC?
No guarantee should be assumed. The Terms and KYC Policy allow compliance verification and temporary holds.
Our Verdict
Classification: confirmed native zero-edge variants with material cap sensitivity and medium offshore platform risk.
MetaWin’s catalogue provides clearer evidence than a generic platform-wide 100% RTP claim: selected ZERO games are explicitly separated from standard 97%–99.5% Originals.
The central weakness is the cap. At high multipliers, even moderate stakes can turn a nominal 100% RTP target into a severely reduced-return configuration. The cap must be incorporated before the claim is accepted.
Use MetaWin ZERO games only after confirming current availability and calculating the cap-safe stake.
