It is a simple single-click numbers generator where all numbers pay some Bitcoins (usually 0.00000442 BTC ), but some numbers pay up to .4000 Bitcoins, which is worth about $180 US. Not a bad chance for 4 seconds work. And you can try again once per hour.
The 'game' is provably fair using a lot of math, and you can verify that at the site.
keep in mind, you are not going to get rich with this, but you will learn about bitcoins and get a little rush once per hour :)

It's a quick account setup at any Wallet site like https://blockchain.info/wallet or https://coinbase.com/signup. You can do it at the site very easily if you wish.
