Open Create a game and connect and verify your Solana wallet. Then name your project and describe your game. Verification signs a message, not a transaction; saving a draft is free. A useful first idea has a player, a goal, and one interesting mechanic. You can come back to your draft in My games.

You do not need a token to prototype a game. Players never need a wallet or token to open a published game.

After saving your draft, review the payment: 0.08 SOL per project, with 8 successful generations and one token launch included. The initial game and subsequent AI edits use the same allowance. The payment’s Solana network fee is separate and shown before signing.

A request in progress reserves a credit. A completed generation consumes it; a failed generation does not consume a completed-generation credit. An unresolved request keeps its reservation while its status is checked.

A generated revision is a starting point for testing. A successful generation does not guarantee a polished or bug-free game.

History keeps your revisions. Inspect the version you want to share, then use Publish game. Publication creates a permanent playable URL for that version. Later edits and publications preserve earlier links.

After publishing, you can prepare the project’s included token launch. Arcabox covers the included launch costs; you still review and approve its wallet transactions. No token purchase is included. Read the publishing and launch guide →
