Minecraft is an interesting game in that it takes multiple approaches to gameplay. One of them is by far the most popular and well-known, and that is survival mode. Find food, get resources, build a shelter, and fight off any bad creatures that spawn in the darkness of night. Another one, for the more artistic or technical players, is creative mode. You have unlimited resources and flight and can build everything from unique and advanced buildings to buildings utilizing the game's form of electricity, Redstone. Then there's adventure mode, where you can download people's maps and play through them without the ability to break or place blocks.

On top of that, the community loves to make their own gamemodes. Minigames are one of the most popular things to play in multiplayer servers on the Java Edition (computer only), and there is a wide variety of minigames to choose from.
