A brief history lesson

In essence, TeacherGaming was born out of a will to help teachers do their very best.

Our story started in Joensuu in 2011, with two university students who believed in the potential of games as learning tools. At the time, we focused our efforts on a specific game: Minecraft.

With the support of a great community of teachers and some superb partners, our MinecraftEdu project grew and evolved, and eventually reached over 15 000 schools all around the world. When Microsoft bought Minecraft in 2015, our version went with it and laid the foundations for today's Minecraft: Education Edition.

Minecraft showed us how a skilled, game-savvy teacher could engage their students with a new medium. After we wrapped up the project, we wanted to see if we could enable any and every educator to do the same. We at TeacherGaming believe that games are a good fit for any classroom, no matter the skill level - and that is where the TeacherGaming Desk comes in.

To start with a clean slate, we founded a new company called 5 More Minutes Ltd, under which the TeacherGaming brand now operates. We are still doing exactly what we did six years ago: putting great games in the hands of students who can make the most of them.
