This quiz contains almost all the Minecraft blocks of the game from 3 editions of the game namely: Java Edition, Bedrock Edition, and Education Edition. The Blocks are in Alphabetical order from A-J, part 2 and 3 contains the rest. This quiz has a lot of blocks so I don't expect everyone to do it in 60 min or even guess every single one of them at all, so you are allowed to do this quiz untimed.
