Great list, and thanks for including the Coin Tasker Xapo Faucet!
I've also developed 3 other instant Xapo faucet games your visitors may find useful if you'd like to add them.
http://vidybit.comWatch short videos (less than 1 minute) for instant bitcoin sent directly to your Xapo Wallet!

http://kenobitcoin.comPick 6 numbers and instantly win bitcoin sent directly to your Xapo wallet!
These faucets are all in Beta, and we're hoping to raise payouts soon, but it is important for me to clarify these are primarily intended for entertainment purposes. We do not have any claim intervals and do not require registration of any kind. You can play these games as often as you like, and earn small amounts of BTC simply for playing. There are no limits or requirements.
Also, you may alternatively use any bitcoin address you like, but if it is not a Xapo address, there is a 5430 satoshi minimum before payout.
We also offer a 20% bonus for all referred sessions on each faucet, and Vidybit currently adds a 5% payout donation to WikiLeaks for every video watched.
Thanks for the consideration!
