Not sure but check the game leaderboard yourself and see which category you should submit it to https://www.speedrun.com/subsurf
Once you're on the category, press "Submit run" and fill out the form.
Also, these are the general forums for the site. So you should ask in the game's forums or Discord instead
No guys, it's a brand new game I'm talking bout here, it's called "Subway Surfers City" it just launched abou a couple of weeks ago from the same developer of subway Surfers classsic game, and i wanted to submit my highest score in that game but there's no leaderboard for that game yet an how to submit it tho?
If you want to submit a new game altogether you need to request it using the Support Hub under 'Add a new game to Speedrun'. Although, because your account needs to be a week old, you will have to wait for at least 5 more days, depending on when precisely you created your account, plus adding social links to your account.
If I had to hazard a guess at why Act said that, assuming he knows about the new(?) game already, the original Subway Surfers board was added in 2017 when site restrictions on adding new boards were quite relaxed, they then tightened considerably over the next few years, and in my opinion at least, nowadays they've relaxed a little again, but mobile games with little distinguishing themselves in terms of popularity or unique gameplay are still rejected quite frequently. If you do all of that you can still try requesting it but a request is not a promise that it'll be added.
If the game is new and not listed yet, try posting a request in the site’s game request or suggestions section. You can also contact moderators or admins directly to ask about adding the game. Once it’s added, you’ll be able to submit your score through the leaderboard.
This is not a new game. It’s just Minecraft bedrock bed wars (hive and cubecraft)
