Bitcoin Zebra is a simple bitcoin faucet. You can claim free bitcoins every hour up to 1000 satoshis. If you use Xapo wallet, an additional 50% is added to your claim and it's paid directly and instantly.

Did you know that everytime you made your claim, you can still double it by rolling a dice and it's totally 100% no risk? This is how to double or even multiply your claim by 1000X!

In this case, I made a claim and got 1500 satoshis and has been paid directly to my Xapo wallet. At the bottom of the notification, there is a box labeled MULTIPLY. Just click on the MULTIPLY box ad to go to the next page

On this page, you choose how many dice to roll. 

Roll ONE dice and if it's a SIX then we will double your faucet payout
Roll TWO dice and if they are both SIXES then we will multiply your faucet payout x 5 
Roll THREE dice and if you get all SIXES we will multiply your faucet payout x 30
Roll FOUR dice and if you get all SIXES we will multiply your faucet payout x 200
Roll FIVE dice and if you get all SIXES we will multiply your faucet payout x 1000

I always roll only 1 dice only since the probability of winning is much greater than if I roll 2 or more dice to come up with all sixes. I have won several times by rolling just 1 dice.
