Build a Roller Coaster

Build a Roller Coaster is a creative tycoon on Roblox developed by Bradenjoy, launched in October 2025. Players design and expand their own roller coaster piece by piece, ride carts to collect Cash from each completed segment, and reinvest in longer and more elaborate track layouts. With 91.4 million visits in under six months and 500-1,200 concurrent players, it reached a scale that few new tycoons achieve. Passive income continues while offline.

The loop starts simple and scales through a prestige system. Equip the Build tool, connect track segments at yellow connection points, then ride a cart to collect the Cash each segment earns. Longer coasters generate more income per ride cycle. Progression builds through the Upgrade system, which costs all current Cash but unlocks new track types, raises the maximum coaster length, and multiplies earnings permanently:

• 🏠 Track Building - connect segments at yellow connection points using the Build tool; types include straight, curved, looped, inverted, corkscrews, and seasonal themed tracks
• 💎 Track Mutations - a modifier system that affects income or cosmetic appearance of placed track segments
• 🏆 Upgrade System - spending all current Cash unlocks new track types, raises the maximum coaster length, and multiplies earnings permanently
• ⏳ Seasonal Tracks - Christmas Tree and Frosty the Snow tracks are available as code rewards, with seasonal content as part of the game's identity
• 🎭 Social Coasters - players can visit each other's coasters and ride other players' carts, earning the Guest badge for the experience

Cash is the only currency - earned from cart rides and spent on track segments and upgrades. A code-rewarded tool called the Careful Remover lets players undo track placements without the usual cost penalty. Crates are obtainable loot containers with bonus rewards. An active Fandom wiki at build-a-roller-coaster.fandom.com covers tracks, crates, mutations, and events in detail.

For a similar build-and-earn tycoon with a golf course theme, Build a Mini Golf follows the same offline income format.
