SaruTobi is a free mobile game for Apple’s iOS devices such as iPhone or the iPad (not yet available for Android devices) that utilizes a simple yet fun and an addictive concept and comes with a Bitcoin theme. You essentially play a monkey called Tobi and there are two modes that you can choose between – either swing your character on his vine to build up momentum and then release him to fly, or swing and jump from vine to vine. In both modes you collect some coins that are called guess how – Bitcoins, but these are only in-game coins and not real Bitcoins. You can use these Bitcoins in-game to purchase some power ups to help you and add some fun while you play, and then there are other coins called Black Coins that you can also collect while you play. These coins can be redeemed for actual Bitcoin Tips, once you have collected at least 12 Black coins you can exchange them for a Bitcoin tip that will be sent to your Bitcoin wallet (you need to enter the address inside the game) and you can also use an email that is registered as a Xapo online Bitcoin wallet as the game apparently has an integrations with that service as well.


Sarutobi is actually the first game for the iOS platform to actually have a feature that rewards players with actual Bitcoins for playing the game, unlike for example the game Bitcoin Billionaire that we have reviewed a while ago. Now, don’t expect too much, you will not get rich playing SaruTobi and earning Bitcoin Tips as a reward, what you are going to get is equivalent to just a few cents. When trying out the game we have concluded that it takes about 15-20 minutes of game play to gather 12 Black Coins that can be redeemed for Bitcoin Tips. The tips you can expect to get are something in the range of between 50 bits and 120 bits, or at least we’ve seen such a rewards so far (5000 to 12000 satoshi). On the other hand this is much better than what many free Bitcoin faucets give you and with SaruTobi you get to have some fun playing an actual game, ideal for wasting some free time.


While playing SaruTobi you can also purchase some in-game content, namely in-game Bitcoins (not real ones) with the cash spent for these going for the Bitcoin Tips that you actually get rewarded with. The rewards wallet also gets filled in from donations and advertisements, though the only advertisement you are going to see for the moment is that of Genesis Mining who have apparently donated 15 THS of Bitcoin cloud mining hashrate to mine directly to the game’s rewards wallet.

If you are interested you are welcome to check out the game yourself, but a bit of warning – we already mentioned that it is a fun and an addictive game, so be careful and don’t spend too much time on it!

There are already quite a few services out there offering you free online Bitcoin wallet service, but we’ve decided to try out Xapo as it supposedly offers something more than the other popular alternatives such as Coinbase for example. Xapo is an free online Bitcoin wallet and a Vault, meaning that you have access to some coins for daily use in your wallet as well as you can securely store coins “offline” in the Vault. The Vault feature however is not the one that we were most interested in, the thing that we wanted to check out was the fact that the service offers an International Debit Card that is linked to your wallet. This supposedly allows you to spend Bitcoins that you already have in your Xapo wallet through your Debit Card as you would normally use a card with actual money in it for payments – withdraw cash on ATMs or pay in a store via a POS terminal for example. This pretty much saves you the trouble to move Bitcoins from your standard wallet software running on your computer to an exchange, selling them for cash and then withdrawing them to a bank account that also may be linked to a debit card. The Xapo debit card is supposed to greatly simplify and speed up this process, or at least that is expected in theory, but we wanted to try it out ourselves.


So we registered our Xapo wallet, a quick and relatively easy process and we’ve got our free online wallet and vault available or almost available. We even got a welcome bonus of 5000 satoshi (50 bits) when we have completed the registration process, not much if you convert it to USD, but then again it is free. However, in order to unlock the full features of the Wallet and Vault we’ve had to confirm our mobile phone number, address and provide an ID number as well to unlock the full wallet functionality. After verifying your identity you will be able to buy Bitcoins, send Bitcoins to other account and transfer your Bitcoins to your vault for secure storage or move them from the Vault to the wallet. The nice thing about the wallet is that besides a standard Bitcoin wallet address that you get you can also use your email address for receiving Bitcoins from services that have been integrated with Xapo with instant transactions and no waiting for confirmations – the ease of use that PayPal provides. This is especially useful when you are using mobile applications where you need to enter your Bitcoin wallet code and cannot just copy and paste the whole hard to remember string of “random” letters and numbers.


So now we come to the part with requesting to get an International Xapo Debit Card that is linked to your wallet. It seems that you need to send a request to get in line for the people waiting for such a card and the weird thing is that you need to link your Facebook and Twitter account in order to successfully complete the card request. There is no way to just go for either Twitter or Facebook, you need to have both and link them to your Xapo account and allow Xapo to post something that you are in the waiting list for their debit card. Now, this is not nice, because not everyone has both Facebook and Twitter accounts, meaning that you need to create accounts at these social media sites just to be able to get in the waiting list for a Xapo debit card. So the getting “early access” is a weird process and according to the service “it can take up to several months to receive the card”.

Apparently if you are an European user you have an alternative to get the so desired Xapo Debit Card linked to your online Bitcoin wallet ahead of “the competition”, all you need to do is to purchase some Bitcoins with Xapo. And in order to purchase Bitcoins from Xapo you need to send a SEPA wire transfer directly from your bank account to the bank account provided by the service. There is no information on how much you need to purchase to qualify, only that additional information will be provided once you do a purchase of coins. Since the first option for getting a Debit Card will take a while apparently, we are going to try the second option to see if it will get us closer to our goal faster – receiving and actually trying the Xapo card. So stay tuned for more details in the next days when we get things moving, meanwhile you can check Xapo yourself if you are interested.

A new update from the latest code of the ccMiner 1.5.40-git SP-MOD fork of the Nvidia GPU miner optimized for the latest Maxwell-based video cards by SP (source) in the form of a compiled Windows binary. The latest version comes with some fixes and additional performance increase in multiple algorithms and seems to be working stable with most of the more common algorithms supported. It seems that the latest code and maybe some releases before that do have some issue with Lyra2RE support on GTX 960, the default launch parameters seem to be wrong resulting in driver crash, so you might want to try manually setting intensity 19 or 20 to make it work properly. The SP-MOD fork is designed for running on Nvidia Maxwell GPUs such as the already available GTX 750, 750 Ti as well as the newer GTX 960, GTX 970 and GTX 980. The windows binary release we have made available here is compiled with support for Compute 5.0 and Compute 5.2 GPUs or with other words only for Maxwell-based cards with CUDA 6.5 and VS2013.
