Curblo is a browser-based massively multiplayer online game that allows players to skateboard, inline skate, or ride BMX in a shared virtual town. The game runs entirely in a web browser with no download or installation required. Players can perform tricks such as grinds, manuals, and airs, chain them into combos, and explore a single persistent environment called Sunny Town, which includes streets, a beach park, a vert ramp, and hidden lines. Every character encountered in the game is controlled by another real player, enabling real-time interaction, shared sessions, and text chat. The game is currently in beta. During this phase, player progress, including rider appearance, points, and unlocked items, is stored locally in the browser. Clearing browser data or switching devices will reset this progress; persistent accounts that carry data across devices are planned for future updates. Players can choose between skateboarding, inline skating, or BMX at any time and customize their rider’s look, gear, and board. The game provides an in-game coach that displays the relevant keyboard controls when needed. A feedback feature is available within the game for players to submit suggestions. Typical use involves opening the game page, selecting a ride, and dropping into the town to practice tricks, explore spots, and interact with other players. Players can form informal crews, set challenges, and session specific locations together. The game is free to play. Future development plans include additional towns, persistent accounts, crew and session features, and unlockable gear. Access to the game is currently open, with no registration required.
