How do I add scoreboards to my game?

I want to add scoreboards to my game, I want to add a scoreboard that show the top fastest people that won a level of my game

Need more information. Do you need a local or global leaderboard? If global - what platform are you making the game for? (web, desktop, Facebook, Android, iOS etc.)

Thanks for answering, global leaderboard, desktop

You have two options:

1. Host leaderboards on you own server. You will need a web-server with MySQL database running on it. Search the Tutorials section for words "MySQL", "PHP", there are plenty of examples.

2. Use one of the online services like Kongregate, GameSparks, Newgrounds, PlayFab, Firebase etc. Again, you will need to do your research, choose which one you want to use, download an addon for it.

I saw a tutorial in youtube but is for Construct 2 that do the same

Better, free.

Is it posible to use c2 plugins in c3? With a tool or something

There is a converter for plugins, but it only makes runtime 2 version.

You should search for correctly ported C3 plugins.

Here is a collection of ported plugins for Firebase:
