The faucet gives free coins for our rocket game and several other sites.
Right now it seems like the Bitcoin faucet for our Rocket game is being a bastard. Try the CLAM faucet for the Rocket game. (We will get Bitcoin working again by this evening.)
I also want to try the rocket game, is it possible to play it without investing? and just playing by the gained BTCs from the faucet?
Absolutely you can play without investing. In fact, most people don't even notice the investing feature IMO.
You can play or invest strictly with the faucet 100% and you can withdraw if you get past the "dust" limit. There are no play requirements.
They could be orbiting?
Like a big crypto circlejerk!
