Have you ever played Agar? Good, then you know how to play SteemAgar, the only difference is that winner gets rewarded with upvotes. You can join the game here - https://steemagar.herokuapp.com/ - This is still in beta so minor bugs could occur

How SteemAgar works?

There is a new match announcement post every 3 hours and 6 minutes from this account, @anonfolderall - Once announcement post has been made, it takes 6 minutes and 30 seconds for the game to start so you have some time to get ready and invite your friends to join too. This is a multiplayer game after all. Once at 6 minutes and 30 seconds, the play button will appear but you need to be logged in via Steemconnect for that to happen. Steemagar doesn't store your keys nor send them anywhere, everything is done by Steemconnect.

How the game works?

The game itself works just like Agar. You try to grow as big as possible by eating food and other players, just remember if they are bigger than you, better run away or get eaten! The game time is limited to 420 seconds. Winner is the one who is biggest in the end of the game. When game time has run out, the winner will have to wait few seconds for confirmation message. You'll get notified when it's done. Everyone can then go and vote his winning comment on the game announcement post. This is encouraged of course! Also consider giving a upvote for the announcement post too as a support! You should also expect a small upvote from @igster account, the creator of this game. Currently it's a manual process but I will be automating it soon. The upvote amount will change according to amount of players in the match. So invite your friends for higher rewards! But most importantly, try to have fun!
