Game City concept — four districts and thirteen discoverable character landmarks.

### The gateway to character worlds Game City is the public gateway to the playable side of Sleepless AI. It connects 13 characters through four districts and thirteen landmarks. [Open Game City](https://www.sleeplessailab.com/games) ### What you can explore today | District | Cast | Status | | -------------------- | ----------------------- | ----------------------- | | Ultimate Super Stars | SOL · NOVA · VEGA · EON | Four flagship landmarks | | ARC//ONE | REN · RUI · KAI | Three group landmarks | | NEVRA | NAMI · MIRA · SENA | Three group landmarks | | HERE//NOW | HARU · MIO · LYRA | Three host landmarks | Users can move between the city overview and four districts. They can focus each character landmark, switch between the Experience and Map Sketch views, and use mouse, touch or keyboard controls. The optional Sonic Link adds the current Game City sound layer. ### Play now Four character-led games are publicly accessible through Game City as of 11 September 2026. Each has its own style, controls and progression. | Character | Game | Experience | | --------- | ----------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------- | | NOVA | [CELL13](https://www.sleeplessailab.com/games/cell13) | An action adventure across Blocks 00–06, with combat, story logs, upgrades, bosses and a New Game+ loop. | | MIRA | [SWEET CITY](https://www.sleeplessailab.com/games/mira) | A candy match-three journey through 12 levels and three districts, with special candies, hints and local progress. | | SENA | [AFTERFRAME](https://www.sleeplessailab.com/games/sena) | A five-day interactive story about recovering imperfect memories, with clues, branching choices, three endings and a memory album. | | HARU | [WILDCARD NIGHT](https://www.sleeplessailab.com/games/haru) | An eight-room action challenge featuring upgrades, a Rule Break ability and a multi-stage confrontation with the House. | The other nine character game gates remain in development. A character landmark or profile does not mean its game is publicly playable. Additional releases will be announced through official channels. ### Before you play * These browser games need an internet connection for the initial load and media delivery; first-load offline play is not promised. * Gameplay progress is stored locally on the current device and browser. It is not a shared cloud account, and clearing browser storage can remove saved progress. * Wallet connection, token ownership and payment are not prerequisites for playing these four current browser releases. Their scores and in-game resources do not imply token rewards. ### How the worlds can grow The remaining gates will translate each character's identity into its own interactive direction. Their platform, access, gameplay, payment and any token or collectible role will be stated with each release. A signal, concept image or locked gate is not a promise of a launch date. > Public availability checked on 11 September 2026. This is an access check, not a full playthrough certification.
