A Demo Version of Blockland is avalible to download, but it is very limited.If you would like to remove the said limits you can buy a Blockland Key from the website found here: http://blockland.us
The full version is not, but you can play the limited demo for free. The demo allows you to explore a limited amount of maps and pre-made creations, as well as edit your avatar. But those are only the pros. The cons of this demo are far more. For one thing, you have limited tools, you can only play in single-player mode (all by yourself) and you have a building limit of only 150 blocks. In the multiplayer version you can chat freely with friends as well as share tools to your (and their) advantage. For every server, one person is the Admin, whose powers are much better than a regular player's. The cost of the full version of Blockland is about $20.00, which is about £13.00.

There is another game like Roblox, with better graphics. Its called Blockland. Even though the demo is free to download, there are some restrictions, that prevent you from playing on an online server (with other people) The full version is $20, with no monthly fees, but that would get rid of the "free" part of your Question. So yes the demo for Blockland is free.
You can play any player if you buy the full version. You can only play single player if you are on demo
