PrisonBlock is unique. Most SkyBlock servers make it to where you automatically get a 250x250 or whatever size island. This is not the case in PrisonBlock. Here, you start out with a 25x25 island. It seems medium sized, but it is actually very small. Once you are able to level up your island (/levelup) then you get a bigger island. You can get up to a size of 450x450.
We have many updates planned already, some of which we are already working on.
