Arena

Arena turns a sentence into a playable game. Describe what you want — out loud or in text — and Arena builds it, runs it, and hands it back playable in seconds. Say what to change and it rebuilds. Draw pixel sprites, upload an image, or generate one with AI, then drop them straight into your game. Publish to the feed with leaderboards, or share a link friends can play right in their browser. Sign in with Seed Vault and pay only for what you build.

Own a Seeker? Your Genesis Token is now worth 1,000 free credits — claimed automatically the first time you sign in, enough to build and refine without topping up first. Show it what you mean. Attach a screenshot or a reference picture to any prompt, and Arena builds towards the look you actually want. Changed your mind? Every refine is now undoable. One tap returns a game to the version before the last change, so experimenting costs you nothing. Signing in is now cryptographic — Seed Vault signs a challenge to prove the wallet is yours. Signing is free and authorises no transaction. The create screen also shows the three newest published games, so there is something to play the moment you open the app. Tap "Connect Seed Vault" on first launch and approve the signature request to create an account — no email or password. Signing is free and authorises no transaction; it only proves the wallet is yours. Testing on a Seeker needs no top-up. The device's Genesis Token is detected on sign-in and grants 1,000 credits automatically, which covers two builds even if every one needs all five attempts. The banner confirming the grant appears at the top of the screen. To build: type or dictate a prompt on the Create tab — "a tapper where you squash bugs before they reach the pizza" works well — and tap "build it". A build takes roughly one to three minutes and reports progress as it goes; you can switch tabs or close the app without losing it. When it finishes, the game opens playable. Type a change into the bar underneath to refine it, or tap "undo" in the header to return to the previous version. To try it without building at all: open the Play tab and play any published game, which is free. Tap the share icon in a game's header to get a link — the link opens the game in Arena if installed, or plays in a browser if not. The same games are playable at https://arena.koretex.ai.
