Welcome Gentle Troll Entertainment! Based on some 15 years of know-how we design and create your Serious Game for Web, PC and mobile devices.

We believe, games still hold vast uncovered potential to convey valuable information to players. We aim to use this potential for the better! That's why we have focused on making games, which explain complex correlations through play. They invite players to experiment, allowing them to reflect on their experiences and make their own deductions. At the same time, we avoid a wagging finger and emphasize on engaging gameplay instead to catalyze learning without removing fun, an important motivator. How does that works? Why not have a look at our award-winning mobile game "The Unstoppables" and see for yourself?

Are you sharing our vision and looking for a team to pour your concern into a Serious Game or Next Reality (VR / AR) application? Then, please, get in touch! We are eager to find out how we can help you best. We develop learning applications and games for teaching and school, customer retention, employee education and training, as well as for use in a scientific context.



We have awesome news for our studio! Our new project receives funding by FFF Bayern for the prototype development. “Dragon’s Roarmance” is a Dating simulation that takes place in the universe of our current project Tavern Talk.


We are beyond excited to let you know that we have been granted production funding for Tavern Talk by the German Games Fund! This brings us a huge step forward to making Tavern Talk a full-blown reality. We already have a Steam page with more information about the game.


Growing up in Germany means you are growing up with the ‘Maus’ and the ‘Elefant’! We are happy to announce that we now manage the ‘ElefantenApp’, a service of WDR. The app was specially developed to meet the needs and abilities of three- to six-year-olds and is free of charge. With it, they can discover the colorful world of the blue elephant with movies, stories, songs and games.


We are proud that our prototype of Tavern Talk receives funding from the FFF Bavaria!
In a world full of magic and fantasy there is a cozy place with magical drinks - the Wayfarer's Inn! Players take on the role of the tavern owner, who is famous for their open ear and extraordinary drinks that help adventurers pass their quest. A Talking Simulator with lot's of DnD humor and RPG hints.


We are very happy and proud that the educational game Klim:S21 got nominated in the category “Education” for TOMMI 2022!
This will bring more attention to climate change and what we can do about it!
The jury says that the game is about “an important topic that concerns and worries many children and young people. […] Every decision made decision has direct consequences and thus trains the understanding of cause and effect.”


Klim:S21 - an educational game on climate adaptation - is now playable for free via the official website! In addition to the game, further material is available for school lessons. The game was developed by Gentle Troll on behalf of rgeo.


The Escape Game “Space Transporters” is now released. Gentle Troll developed the Serious Game for the Joachim Herz Stiftung. The Foundation will present the game during the didacta in Cologne from 7 to 11 of June. The Educational Game teaches basic economic assumptions and is meant for students.


We proudly presented our upcoming Serious Game Klim:S21, developed for the PH Heidelberg, on the conference "One Planet Left" of Stiftung Digitale Spielekultur. WDR released an audio about the conference, climate crisis and Serious Games that meet this topic: One Planet Left: Spielen gegen die Klimakrise. Listen and enjoy!

The game was developed on behalf of ZD.B (part of Bayern Innovativ) to learn more about cybersecurity.

School can do more than just provide specialist knowledge! In two computer-aided simulation games of MTO Psychologische Forschung und Beratung pupils can train their social and personal skills as well as their problem-solving competence in two different scenarios. Gentle Troll gave the learning games an attractive look and developed graphics, illustrations and animations of characters and the environment.


Are games just children's pastimes? Not in classical antiquity! There, all members of society were playing games: men, women, children, free citizens, slaves – and as lore says, even gods! The "Locus Ludi" project partners - the University of Fribourg and the University of Applied Arts Vienna - study four classical games. Based on their scientific results Gentle Troll Entertainment and Causa Creations develop the modern versions for computers and smartphones.


The browser game "How to Feed a Dragon" shows customers of the laboratory equipment manufacturer Brand the functions of the new HandyStep touch pipette. The player finds a dragon's nest and needs to feed the small, newly hatched dragons using the pipette. Each dragonling has a different need and grows at a different speed so the amount and content of the pipette must be chosen appropriately. If the player has done everything right, the dragons are big enough to fly away.


New member on board! We are happy that Lena supports Gentle Troll Entertainment as specialist for PR & marketing. In the future, she gives insights into our work as game developers and feeds the media and community with the latest news of our games.


With four interactive installations in the Archeology Museum Bad Königshofen visitors can now experience the life of the people in the Stone and Bronze Ages.

"Radicalization" was the topic of this year's game jam organized by the German Federal Agency for Civic Education. Our team (Gentle Troll & friends) created a game named "De-Republica", which picks up on current radicalization tendencies in politics: In this local multiplayer game, players have to push their increasingly perverting political agenda, secretly voting on various bills via their own smartphones. The aim is to achieve absolute power by radicalizing society.


We have kicked off this year with two additional partnerships with German universities: Besides our established cooperation with the junior professorship for Serious Games of the University of Ulm, we have now officially build up tighter relationships with the Creative Media Research and Development Group of the HTW Berlin. Moreover, we have partnered up with the Chair for Human-Computer Interaction of the University of Würzburg and are now looking forward to new collaborations on exciting Virtual, Augmented and Mixed Reality projects.


We were offered the fantastic opportunity to write up a development case study about our award-winning game „The Unstoppables“ for the internationally known Making Games magazine. Pick one up to catch a glimpse behind the curtains at Gentle Troll! (German reading skills recommended ;))


One of the first MeisterPOWER classroom playtests has received fantastic coverage by one of Germany's major craft-focused magazines. The article reflects pupils were engaged and learned valuable lessons about entrepreneurship and handicraft business. Mission accomplished! :)
