You start by downloading the Minecraft Trial for your Android phone. The game is free, but it is a time-limited trial. You can create, explore and survive in the trial world, but the world will not transfer to the full game.
The first thing you'll need to do is create your character. You can choose from one of three different characters: a man, a woman, or a skeleton. Each character has different strengths and weaknesses, so choose wisely!
Once you've created your character, you'll be dropped into the world. The first thing you'll need to do is gather resources. You can chop down trees, mine for stone, and gather other resources to help you survive.
There are two main ways to play the game: survival mode and creative mode. In survival mode, you'll need to gather resources to build shelter and defend yourself from hostile mobs. In creative mode, you'll have unlimited resources and can build anything you can imagine.
The Minecraft Trial is a great way to get a taste of the game. It's free, and you can try out different modes to see which one you like best. Just be aware that the trial world will not transfer to the full game.
