Where play grows into learning
We're TumbleTree Studios — we craft friendly games and learning adventures for children and other curious minds.
Three friends, one little tree, big ideas
TumbleTree Studios is a small studio from Bruchsal, Germany — planted in October 2025 by three friends who believe screen time can be kind, clever and full of wonder.
We make apps where children explore, giggle and learn along the way. No pressure, no tricks — just honest fun that grows with you.
Curiosity first
Every tap should spark a question, not just a reaction.
Safe by design
No hidden traps, no pressure, no dark patterns — promised.
Made together
Parents, kids and us — growing this tree as a team.
The TumbleTree App is sprouting
Our flagship is in the making: a friendly world of mini-games and learning adventures for children and other curious minds — completely ad-free. We're planting, watering and testing — and we can't wait to show you.
Watch it grow — follow along:
Dropigon — drop, merge, giggle
Our first game! Drop colorful pieces, merge them into bigger ones and chase your high score. Easy to learn, hard to put down — imagine Tetris meeting a fruity merge puzzle.
Easy to pick up
One finger is all you need.
Make it yours
Unlock playful skins and colors.
Climb the board
Challenge your family and friends.

No dark patterns, no pressure to spend, no endless loops. Playtime should end with a smile.
Always transparent
