Use this referral link: Rollercoin for an extra 1000 satoshi (withdrawal minimum is 10,000).
Rollercoin is structured as a mining simulator. You start out with a basic computer which earns only fractions of satoshis every 10 minutes but the more games you play, the more upgrades you get. Eventually you can earn enough for a decent mining computer or even monster mining rigs.
Hit the Gain Power button to upgrade your mining rig to earn more. And thanks to Austras for his comment below, you dont have to wait for the games to load; as soon as it starts to load you can press the games button on top and your power will increase. 
It can take some time to earn enough for mining rigs but you can spend a few of your own satoshi (or DOGE or ETH) in the marketplace and buy your own virtual mining rig and increase your earnings exponentially.
Or, keep it free to play and have fun while earning crypto and upgrade your virtual mining rig with time!
