One block is prevalent among all Minecraft maps. One Block Map (1.20, 1.19) is a survival map in which you get a lonely block floating in the void. You can mine the same block over and over, giving you basic materials that slowly improve. There are 10 levels in total. The type of block that appears will depend on the stage you are in, for example, if you are in the forest stage, you can get grass, wood, or clay.
