One shared arena. Six-minute matches. After a 10-second warmup, active play scores with at least two live players. Devnet SOL rewards require a funded test pool.

Practice works without a wallet. Ranked requires an available game server.

    Devnet test funds have no monetary value. No live token fees or mainnet payouts. Signing in proves wallet ownership; it does not send a transaction.

    ARENA OVERVIEW
    THE PLAYBOOK

    Grow your bag.

    Supply dots give steady, modest growth; smaller split bubbles collect them more efficiently. Capture smaller holders for a bigger share of the supply. Your six-second spawn shield protects you from being eaten, but you can absorb smaller holders immediately. After it expires, bigger holders can eat you. Stay inside the outer wall.

    MOVEWASD or arrow keys take over from the mouse. Release the keys to stop; click the arena to return to mouse steering. You can also drag on touch screens. Holding your mouse at a screen edge keeps you moving.
    SPACESplit in your movement direction to catch smaller holders. Smaller bubbles move faster and earn up to double mass from arena dots. The bonus fades as each bubble grows. Up to 16 bubbles.
    CConsolidate after the 5-second split cooldown. Four or more bubbles form hub clusters. From eight bubbles, small offshoots and extra connections between satellites make each formation different. Nearby outer bubbles send up to 30% of each arena-dot pickup to their hub; they keep at least 70%. Feeding stops at 45% of cluster mass. Larger hubs move more slowly and remain vulnerable.
    ETap or hold E to drop orbs behind you and gain a small forward boost. Each burst uses some of your size. Dropped orbs return their normal mass without a collection bonus.
    ROUNDPractice rounds last six minutes. Time in the top 10 builds round points; higher ranks earn faster. Active play always earns cosmetic XP for your home constellation. Each new round starts fresh.

    Practice uses AI opponents and has no payouts. Ranked devnet uses a shared server and test SOL only; matches keep running while menus are open. Home progression is cosmetic and saved on this browser.
    TAKE A BREATHER

    Arena paused.

    Your bubbles are safe while you’re away.

    Off shows each ranked update as it arrives. Movement may look more stepped. Network travel time still applies.

    Lighter lowers arena resolution and removes floor lighting and panel blur. Bubble rings and action effects stay on.

    For smooth play, keep graphics acceleration enabled in your browser.
    PERFORMANCE

    Smoother play.

    Graphics acceleration lets your browser use your GPU. If FPS is low, check this setting first.

    1. In Chrome or Edge, open Settings and search for graphics acceleration. Turn on Use graphics acceleration when available.
    2. Leave your round and save any other work, then relaunch your browser when prompted.
    3. Reopen the game and check Menu → Show performance. You can also compare Neon and Lighter graphics.

    Other apps, extensions and power-saving settings can also affect FPS. The game detects low frame rates, but cannot reliably read your browser's acceleration setting.
