Unfortunately for Android users, the Blockchain Game is not available for them at the moment. The developers have released the game for iOS only, and there is no indication an Android version will ever see the light of day. That is, unless this app becomes incredibly popular over the next few months, so there is no need to despair just yet.
The objective of Blockchain Game is pretty straightforward: players have to build a blockchain by stopping the next block at the right time and position. The longer their blockchain becomes, the bigger rewards they will earn. All of these rewards are paid out in Bitcoin and will be sent to the address specified in the user’s profile.
