You can play Fuzzycraft in two ways.
- You can download the WAN Launcher from the development section. This will get you started quickly with a new game
- You can download individual packages and install them into an existing game of modded Minecraft. Check for an explanation the manual of the tool you are using. You will at least need Fuzzy Core and one other to be able to play. You should also make sure that you have the correct version.
In all cases, you will need to have bought Minecraft from their website.
