Finish 10 Online Games
You need to finish ten online games to unlock this achievement to unlock. You cannot unlock this versus AI. You do not need to be on the leaderboard or have any specific ELO, nor do you need to actually win the games; you simply need to finish them.

Get a non-provisional Elo Rating (play 15 rated online games).
Play 15 rated games online to unlock this achievement. You do not have to win for those games to count.


Are you ready for the perfect storm? Beat someone ranked 20 points above you (in a rated game when both of you exist on the leaderboard).
You'll need to be on the leaderboard prior to doing this, which means you need to have played 15 online games prior to trying to unlock this achievement. You should have unlocked "Arpad Elo" before trying this one. You can either play a online and win against a random opponent, or if you have a friend ranked 20 points or higher that is willing to throw the match for you.

Subsequently, if you have nobody and can't beat anyone online, you can go as far as making a second Steam account, playing 15 matches against yourself (make sure your throwaway account is ranked 20+ points higher by the end) and then beat that account, which will unlock this achievement. It's an insanely roundabout way of doing it, but it's possible.

Financially support the development of Simply Chess.
This final achievement you'll actually have to shell out money for, which, for most of you will be rather annoying. If you're willing to support the developer, you'll have to buy their premium upgrade for $4.99 USD (or your region's equivalent). Once you purchase the upgrade, the achievement will unlock.
