Yes you are right, the free playground is to learn how the game works and the earned value does not get credited.
We soon will do advertising and give out a press info so the playgrounds will fill and you can play against other players for real bitcoins
So if you see someone playing on a paid playground feel free to join and battle him.
Suggestion: make the free playground pay out too, but much much lower than the paid playground. Say like a faucet, at least to start and have people use it, in the future paid by banners/advertising.
This way more people will start using it to get it started, I am now a very lonely ball playing around.
Paid playgrounds are now 0.1 mbtc, 5 mbtc and 10 mbtc... I miss the obvious 1 mbtc option: not too high, not too low.
Oh, forgot to say: KUDDOS for making bitcoin agar! Finally someone did it
I think this would be a lot more popular if the site admin didn't need to take "a few percent" out of the bet pool. I don't see why that's necessary, it's like you're just trying to get rich with minimal effort... agar.io is completely free and can sustain itself even with a large number of players... In fact there's nothing stopping anyone from making a free version of chopcoin.io that uses ads to pay for its server rather than taking a huge chunk from the bet pool and reducing people's winnings for no reason.
I agree! Or... at least for the startup until the site is big and popular. It won't matter much now if you get a percentage of not much, so let the site grow a bit first.
