Last verified 2026-08-05. *Asked and answered* # Sunken City Riches FAQ Direct answers to the questions players actually type — about the RTP builds, the 29 September 2026 release, the maximum win, the side bets, and where the numbers circulating elsewhere came from. Everything here is sourced from Stakelogic's own material, and anything unpublished is marked as unpublished rather than filled in with a guess. **Q: What is Sunken City Riches?** A video slot from Stakelogic with 1024 payways and maximum 5/5 volatility, released across the network on 29 September 2026. Top multiplier x15,000, quoted maximum win €450,000, and nine features headed by Payway Maker, Split Symbols and Super Stake. **Q: When is Sunken City Riches released?** 29 September 2026, per Stakelogic's Q3 2026 network roadmap. Individual casinos sometimes receive an exclusive early-release window a few days earlier. Affiliate pages listing «May 2026» or «22 September 2026» are copying placeholder data and are wrong. **Q: What is the RTP of Sunken City Riches?** Three certified builds: 94.00% (game ID 14420094), 95.50% (14420095) and 96.00% (14420096). Stakelogic's product page quotes 96.01%. Each build gains roughly 1% more with the Spin to Win side bet active. Your casino decides which one it runs. **Q: How do I check which RTP version I am playing?** Open the game, tap the menu or «i» icon, open the paytable or game information screen, and read the RTP line. Licensed casinos must disclose it. If it says 94.00%, the same title may run at 96.00% at another licensed casino. **Q: How do you win in Sunken City Riches?** By landing three or more matching symbols on adjacent reels starting from the leftmost reel, across any of the 1024 payways. Every outcome is drawn by a certified RNG the moment you spin, so no strategy alters the odds. What you control is the RTP build, the Spin to Win side bet, your stake size relative to bankroll, and when you stop. **Q: What is the maximum win?** x15,000 your stake, published by Stakelogic as €450,000 — which corresponds to a €30 stake. On a maximum-volatility slot this is a lottery-tier event and belongs nowhere in your bankroll planning. **Q: Is Sunken City Riches high volatility?** It is the maximum band, 5 out of 5. Expect long dry spells in the base game with the return concentrated in rare, large bonus payouts. It suits small stakes across many spins, not large stakes across a short session. **Q: Can I play Sunken City Riches for free?** Yes. Stakelogic publishes a free demo on its own site and supplies demo builds to licensed casinos. Same RNG, same maths, fake balance. No download and no account needed for the studio demo. **Q: Do I need to download anything?** No. It is an HTML5 game that runs in any modern desktop or mobile browser. There is no app and no plug-in. **Q: Can I play it on my phone?** Yes, on both iOS and Android through the mobile browser. Stakelogic builds its slots mobile-first and supports portrait play. **Q: What is Super Stake and is it worth it?** Stakelogic's trademark side bet: it doubles your stake and switches on an enhanced game state — extra scatters, added wilds, or low-paying symbols removed, depending on the title — which raises how often you reach the bonus. It buys frequency, not edge. If you use it, halve your base stake first so your real per-spin exposure does not double. **Q: What is Spin to Win?** The «STW» side bet marked against each RTP build on Stakelogic's roadmap. Activating it adds approximately +1% RTP, taking a 96.00% build to about 97.00%. It is the only switch in the game that measurably improves your long-run return. **Q: How does the Super Wheel work?** It can trigger on any random spin and hands you off to a live studio with a human host and a 54-segment money wheel. Published network figures: 93% RTP on the wheel and a hit rate of about 1 in 75. Three further live rounds sit behind it — Vegas Drops, Vegas Diamonds and Vegas Hold 'n' Spin. **Q: Is there a bonus buy in Sunken City Riches?** Stakelogic's roadmap lists Super Stake and Spin to Win as the paid-entry mechanics rather than a direct feature buy. Where bonus buys exist at all, they are banned in several regulated markets including the UK and the Netherlands. Check the in-game info screen for your jurisdiction. **Q: How many reels and rows does it have?** Stakelogic has not published the grid yet. 1024 ways is classically produced by a 5×4 grid (4⁵ = 1024), and Stakelogic has used that layout for other 1024-way titles — but Payway Maker expands positions during play, so the grid may not be static. We will publish the confirmed layout on release day rather than state a guess as fact. **Q: What is the minimum and maximum bet?** Not published yet. The €450,000 maximum win at x15,000 implies a €30 maximum stake on the studio's own figures, but bet ranges are usually set per operator and per currency. Pages currently quoting «€0.20 to €100» are copying a placeholder listing. **Q: What is the hit frequency?** Not published. On a 5/5 volatility slot expect it to be low by design — that is what maximum volatility means. We will add the figure when Stakelogic publishes it. **Q: Is Sunken City Riches rigged?** No. Stakelogic is a licensed supplier and its RNG and RTP builds are independently certified — that is what the three game IDs exist for. What deserves your attention is which build your casino licensed: a 94.00% build is legal, certified, and materially worse for you than the 96.00% one. **Q: Can I improve my chances of winning?** You cannot change the odds of any spin. You can reduce what the game costs you: play the 96.00% build, understand the Spin to Win side bet, size stakes so the bankroll survives the variance, and set a loss limit before you start. Spin timing, bet progressions and «hot/cold» streaks do nothing at all. **Q: Where can I play Sunken City Riches?** At licensed casinos carrying the Stakelogic network from 29 September 2026. Pick one licensed in your own jurisdiction, then check its RTP build before playing. This site is an independent guide — we do not take wagers and we are not a casino. **Q: Is the demo the same as the real money game?** The RNG, maths model and features are identical. Two things differ: demo winnings cannot be withdrawn, and the Super Wheel live layer is usually simulated or unavailable in demo because it hands off to a real live studio. **Q: Who made Sunken City Riches?** Stakelogic, a Netherlands-based studio founded in 2015 and known for the Super Stake side bet and the industry-first Super Wheel live crossover. Sunken City Riches is its September 2026 network flagship. ## Still deciding whether to play? Start with the free demo — identical RNG, identical maths, fake balance — then check which RTP build your casino actually runs. [Demo guide](/demo/) [RTP guide](/rtp/)
