Use your fist, or shovel if one is provided, to break blocks around the arena with the aim of causing other players to fall in

One popular strategy is to go to a corner and break all the blocks around you that are within arms reach, making you safe from attack. If someone else decided to use this strategy as well, however, you will be left at a stalemate. Try not to break blocks unnecessarily, as this will put you in as much danger as anyone else.
