GridGuesser is a free Formula 1 prediction fan game with clean security checks, but it offers an Android app file outside the Play Store
GridGuesser describes itself as an independent fan project that runs a free Formula 1 prediction game. The site says there is no entry fee and no money is staked. It also says it is not affiliated with Formula 1, the FIA or any team. Security checks found no threats, and the connection is encrypted. The domain is under a year old. Independent web research returned nothing either way, and the person behind the site is not named. The site also invites visitors to install an Android app directly from a file instead of through the Play Store. For these reasons, the score is Low Risk rather than Safe.

Investigation Brief
GridGuesser describes itself as an independent fan project that runs a free Formula 1 prediction game. The site says there is no entry fee and no money is staked. It also says it is not affiliated with Formula 1, the FIA or any team. Security checks found no threats, and the connection is encrypted. The domain is under a year old. Independent web research returned nothing either way, and the person behind the site is not named. The site also invites visitors to install an Android app directly from a file instead of through the Play Store. For these reasons, the score is Low Risk rather than Safe.
A free fan-made F1 game with no money involved
The site says nothing of monetary value is won or lost. It says scores come from the official race results, and it states that it has no paid tier.
The site is open that it is unofficial. It says it is not affiliated with or endorsed by Formula 1, the FIA or any team. This means it is not posing as the official brand.
Its outbound links go to motorsport news sites, formula1.com, Discord and Reddit. None of these links were marked as paid or commercial.
Clean technical checks, with one sideloading caveat
None of 93 security engines flagged the site. Safe Browsing gave no warning, and the encrypted connection is valid. These results mean nothing harmful was detected, but they do not prove the site is safe.
The site offers a 'Download for Android' link. It says the app is 'Not on the Play Store yet' and tells visitors to allow the install when their phone asks. Installing apps this way skips the checks the Play Store applies. No harmful behaviour was observed in this file, but it was not analysed either.
Why the score is 80
The saved checks found no material threat, but the evidence was not strong enough for the highest Safe tier. Coverage remains separate so missing sources cannot be mistaken for clean results.

Web research findings
Independent findings for gridguesser.online, including public complaints, named review sources, registration records, and look-alike-domain evidence. A missing result is shown as unverified, never converted into a clean bill of health.
No independently sourced scam reports or credibility records were found for gridguesser.online. That is common for new or low-traffic sites and does not clear the site.

Domain & infrastructure
The plumbing behind the site — who registered it, how it’s encrypted, where it’s hosted, and where it links out. A valid certificate or a calm server doesn’t mean the business is honest — scam sites pass these checks too. Use this to corroborate the verdict, not to overturn it.

Domain & Encryption
Cloudflare DNS is used by legitimate and scam sites alike, so it does not identify who runs the site.
Certificate issued for gridguesser.online.
A shared Cloudflare address answers for many sites, so it is not the site's own server and says nothing about who runs it.

GridGuesser describes itself as an independent fan project that runs a free Formula 1 prediction game. The site says there is no entry fee and no money is staked. It also says it is not affiliated with Formula 1, the FIA or any team. Security checks found no threats, and the connection is encrypted. The domain is under a year old.
