One build. A whole neighborhood.
An instant city-builder game: every build is one round, and the neighborhood that rises sets the return, from green beginnings up to a 250× Metropolis.
3D City: Neighborhoods is an instant game set on a living 3D island city. The player picks a plot at the edge of the island, sets the bet and presses BUILD. One draw, made when the bet is placed, decides the neighborhood. A construction scene then raises it on the plot, and the neighborhood's multiplier sets the return. There are twelve neighborhoods: Green beginnings, which returns nothing; suburbs, residential blocks and skyline districts; observatories; the Golden and Grand landmarks; and the Metropolis at 250×.
Every neighborhood stays in the player's city. The island grows as they build, with traffic, residents, day and night, and a Town Hall, a city museum and a botanical conservatory at 25, 50 and 100 neighborhoods. In real money the city is saved to the player's account, so it's waiting for them next session.
Game spec sheet.
| Genre | Instant game · city builder · 3D HTML5 casino game |
| Game Type | Single-player instant game: every build is its own round, with one stake and one payout |
| Round | Choose a plot and a bet, then press BUILD. The result is decided at the bet, and the construction plays out in about 2.4 seconds, the same length for every result |
| Neighborhoods | Green beginnings 0×, Garden suburb 0.50×, Residential block 1×, Mixed-use quarter 2×, Premium residences 3×, Garden district 4×, Skyline district 5×, City observatory 8×, Grand observatory 10×, Golden landmark 25×, Grand landmark 100×, Metropolis 250×. The same ladder at every RTP; a lower RTP only makes Green beginnings a little more likely |
| Odds (96% RTP) | A build returns something 53.9% of the time: 19.5% return half the stake, 19.5% return the stake, and 14.9% win 2× or more. 5× or more comes 1 in 27 builds, 25× or more 1 in 342, and the 250× Metropolis 1 in 10,260. Players see the ladder; the exact odds are in the operator documentation |
| Payout | Bet × the neighborhood's multiplier (stake included). Garden suburb is a partial return, Residential block returns the stake, and Green beginnings loses it |
| Volatility | Medium |
| Max Win | 250× bet (Metropolis), enforced server-side. Operators can set a lower cap from 2× upward and the RTP stays exact |
| RTP Variants | 92 / 94 / 96 / 97%, exact for every round, each simulated over 20 million rounds |
| Fairness | Provably fair, per-operator toggle. The seed is committed before the build, and the draw, neighborhood and payout are verifiable via the in-game panel or the public verification page. Where the player builds never changes the result |
| Platforms | Desktop + mobile (HTML5, 3D), with portrait and landscape layouts on phones and a photo mode; demo mode included |
| Delivery | Iframe embed via SDK launch URL |
