Minecraft is an open-world sandbox game where you can do anything from slay mobs and survive to have unlimited resources, invincibility, and build whatever you want along with playing with friends. The game has to be purchased though and can't be played for free. Sorry man.

Sorry bro… You gotta pay… It's not free…

Minecraft is an open world game that has no specific goals for the player to accomplish, allowing players a large amount of freedom in choosing how to play the game. However, there's an achievement system. The gameplay by default is first person, but players have the option to play in third person mode. The core gameplay revolves around breaking and placing blocks. The game world is essentially composed of rough 3D objects-mainly cubes-that are arranged in a fixed grid pattern and represent different materials, such as dirt, stone, various ores, water, and tree trunks. While players can move freely across the world, objects and items can only be placed at fixed locations relative to the grid. Players can gather these material blocks and place them elsewhere, thus allowing for various constructions. You can only get minecraft for free if you pirate it, and that most likey has viruses and even if you find a working version, you can't play multiplayer
