←Runoff

Runoff has never run on an Android phone. Not once — it was built for iOS and desktop, and the Android version compiled for the first time this week. It needs real devices under it before it goes anywhere near the Play Store, and Google also asks a solo developer to run a closed test before publishing. If you have an Android phone, joining takes about two minutes and genuinely helps.

How to join

Three taps, all on Google's side. Use the Google account that's signed in on your Android phone for every one of them — Play ties test access to that exact account. Nothing here comes to us: no form, no email. Google keeps the count, and we read it in the Play Console.

Same account throughout Become a tester

1. Join the tester group. Google Play only admits testers through a Google Group, so this is the door. Joining is instant and needs no approval. Join runoff-testers
2. Opt in on Google Play. Play looks up the group before it lets you in, and a membership that's seconds old can take a few minutes to show. If it says you're not a tester yet, give it a moment and reload. Opt in to the test
3. Install Runoff and keep it installed. Play as much or as little as you like. Google counts you from the moment you opt in. Install from Google Play

What is worth reporting

This is a first build on a platform it has never run on, so the useful feedback is the boring kind — does it work at all, and does it work like a game rather than like a demo.

• Anything magenta or solid black. The single most likely fault. Android compiled its own shader set for the first time, and when one goes missing the surface renders bright pink or dead black while everything else looks perfect. If you see it, that is a real bug and we want to know.
• The on-screen sticks. Both thumbs, no grip, and the whole game is holding a precise deflection. If they feel laggy, or land in the wrong place for your hands, say so.
• Frame rate. Especially in the lit tunnels, which carry a lot of small lights.
• Head-to-head. Two devices on the same Wi-Fi, one hosts and shows an address, the other types it in. It has never been tried between two Android phones.

Questions people actually ask

Is this the finished game?

The game is finished; this build of it is not proven. Ten circuits, four riders and head-to-head racing are all in and all complete — but no one has played any of it on an Android device, so treat it as an early build rather than a polished release. That is the honest answer and it is why the list above exists.

Does it cost anything to test?

No. Runoff is a paid game, but testers never pay for it: Google Play hands the build to everyone in the test at no charge, for as long as the test runs. There is no card to enter and no trial to cancel.

The people who join earliest also get the finished game free when it launches — we send a Google Play code, which redeems against the paid listing exactly as a purchase would. You do not need to do anything to qualify beyond joining and staying in the test.

Which Google account should I use?

The one signed in on your Android phone. Play ties test access to that exact account, so joining the group with another one won't unlock the build. A Workspace address on your own domain is fine — it's still a Google account.

Do you collect my email?

No. There's nothing on this page to fill in. Joining the group and opting in both happen on Google's side, and all we ever see is a tester count in the Play Console. Same as the game itself: no analytics, no tracking, nothing about you. If you email a bug report we obviously have your address for as long as that conversation lasts, and nothing more.

Does the game phone home?

No. Runoff plays entirely offline; its only network feature is head-to-head racing, which talks directly to the other player's device on your own network and goes no further. The privacy policy spells out exactly what that means, including why the Android build declares an internet permission it never uses to reach the internet.

Can I stop?

Whenever you like. Leave the test from the same Google Play page you opted in on, and uninstall as you would any app. Nobody is chased and leaving early isn't held against anyone.
