This is actually pretty cool to just do in your downtime for a little extra BTC. The site game starts you off with 20Ghash/s and pays out at .01BTC instantly. You can "hack" other players in the cloud to gain more gh/s or buy it with bonus points(gained from logging in) or the btc you mined (for free). No deposit or anything like that, just a very addicting thing to come across being I have been into BTC since 2011. Hope you all enjoy and I will be here to answer questions if needed.
Good luck, I've only been playing for 2 days and when I hit the double Gh/s button (stays active for an hr, then press it again) I shoot up to 300gh/s already.
Edit because of link tinyurl d0t com / FreeCloudMining
