The Mystery at Greveholm (Mysteriet på Greveholm) was a very popular TV-Christmas show broadcasted on Swedish National Television (SVT) in 1996. In Sweden there is a tradition of creating a Advents Calendar TV-show each year with an episode showing each day for December all the way up to christmas eve (so 24 episodes). Greveholm was as mentioned aired in 1996 and then had a follow up for Christmas 2012. Both of these installements were very popular. The first show (from 1996 has been voted one of the best calender-series of all time several times by the viewers).

1997 a CD-ROM game was released based on the TV-series and it was a smash hit. It was also the first game produced togheter with SVT and the calender shows, there was several to follow. On top of that it was one of the few first really big computer game productions for kids in sweden back then.

The first game was followed by a part two the year after which also was well recieved. The third follow-up game was released some years later.

Pelle Svanslös (Pelle Tailess) is a well recognised swedish illustrated childrens book, it has also been adopted for the cinemas as well as been a christmas advent calendar on the Swdish national television (SVT).
I was part of working on an adatotion of some of the books as an interactive book for smaller children as well as the game developer and publisher for a platformer game Pelle Svanslös & The Treasure Hunt. Both of these products were released on CD-ROM and did well in their initial release in the year 2000. Due to changes in the publishing world of games in Sweden back in those days, the game got marginalised and removed from the store shelves in a wider sweep from large publishers to eliminate smaller actors on the game market. Back then there were no other channels for distribution so the games got lost in time.

When Apple had released their iPhone and new ways of distributing for a larger audience was opening up I started working on my own children games together with the people I hang with using our own IP’s.
We created a couple of apps, but since this was happening when the iPhone was new and people didn’t yet feel comfortable handing over their shiny precious devices to their children the market wasn’t really there yet. The apps did get a lot of praise and caught the attention of a publisher in the US which lead to a long series of children apps and games over the coming decade.
Here are some examples of my own apps that we created,

As a result of starting to create and distribute my own children apps, I started working with some larger publishers in USA, creating children game apps for iOS and Android on several larger IP’s. This was an exciting time that held a lot of promise for the future. Unfortunately the app market changed and gravitated towards in-app purchases which made it hard to maintain a valid business modell when targeting children (although there were plenty of actors who did not hesitate to adopt to this new trend).
Still, there were a couple of years when working on and targeting mobile devices gave me the opportunity to dive into several interesting and uniqe projects where many of these apps ended up being at the top of list of popular children’s apps, winning awards and getting rave reviews.
Here are some examples of those apps

Miss Spider

Thomas & Friends

Sesame Street

Angelina Ballerina

I continued creating apps for children based on well known IPs, first focusing on iOS and Android but eventually getting back to the dirstribution of games on the internet as well.
The industry was now slowly gravitating towards making children’s apps as a means of markeing for the brand itself or as an educational venue.
Most apps at this point were/are free to download and play or used in schools as a complement to other learning media. The latest app that I worked on Stopp Min Kropp is used in public schools in Sweden along with movies and books in the same setting and was released in the fall of 2024 and has been well recieved by the students and teachers.

Working with Captain Underpants and the other characters of Dav Pilkey and his universe was some of the more fun productions I’ve done as a Game Developer and a creative person. That level of “going crazy” and coming up with unconventional ideas and solutions is not common in the commercial world. The Captain Underpants app was an unusual book/game app that got a lot of praise and the multiplayer online game Planet Pilkey was an elaborate show off of Dav’s complete lineup of characters and his wild universe/mind.

Unfortunatly Planet Pilkey was eventually shut down to make place for Home Base and some of the Planet Pilkey minigames and activities where moved into that online multiplayer platform and shared space with lots of other games featuring all of the brands for children in the Scholastic Inc catalouge. We helped creating some of those smaller games for this platform the following years.
Home Base was discontinued end of November 2025 and is no longer available.

Here are some screenshots and videos from these productions.
