Crypto-City was a bitcoin game site. that in my [ Watch List ]. it was a simple game. there are not much to say. you will have a building in the beginning. and it will give 1 satoshi per sec. up to 500 satoshi will stop add untilate you claim it.
you can buy other building to increase your profit.
minimum withdraw limit is 5000 satoshi for now, at this speed i guess first withdraw will be soon.
2016/12/10 : became Scam!
2016/11/08 : received 7th times. each times about 5-6,000 satoshi.
