A huge Minecraft convention is taking place this weekend in London.
10,000 fans from around the world have gathered at Minecon to see the latest Minecraft tech, and share their top mining tips.
Popular YouTube stars such as Stampy, and Dan from the The Diamond Minecart are at the huge event.
There is also a costume competition, sessions to share Minecraft mod tips, as well as talks from the game's developers.
The Minecraft coding team are there to talk about future features of the game, including teaming up with Telltale Games for a new Story-Mode.
Microsoft, the tech giant that owns Minecraft, were also giving away golden tickets to some people, to try out the new Hololens virtual reality headset.
