Where to get minecraft without buying?

Ask for it as a gift. The holidays are approaching, ask your family to get it for you on whichever device you play games on.

otherwise, get a job and save up for it like the rest of us. A lot of stores are hiring for extra help during the season, if you're 15, ask for a workers permit from your local government, you will need your parents permission, and you will only work part time.

if you're over 18, get a job. Work an appropriate schedule if you're in school. If not in school, work full time 40 hours / week.

consider joining the military if you're 18 / have a high school diploma. It would only be four to six years, unless you like it, but as long as your are medically and have no legal issues in the past or pending, see a recruiter for what they can offer you for a job, education and training, all of which they will provide for you.

If you ask your family for an account you could try and buy 1 for cheap (around $3-5) on Twitter. Just make sure they've made legit sales before.

You can download it directly from internet. Me and my friend just did cause he loves it.
All we needed was the utorrent and we got the torrent from Kat.cr. I can send you an video based on how to download minecraft.
