With over 100 years’ experience, Keesing has become its own unique seven-letter concept.
In 1911 Keesing was founded by the Amsterdam-based journalist Isaäc Keesing. Owing to the success of his financial archives, Keesing could start his own publishing house in 1916. With the brand Denksport, Keesing introduced the first puzzle magazine in the Dutch market, setting off a new craze and ultimately becoming a household name. After 1945 Keesing expanded to cover different language zones. Keesing France, established in 1955, has been especially successful with its brand Sport Cérébral.
Since its inception Keesing has flourished as a result of the dedication that comes from being a family-owned business. Because of its growing success and visibility however, Keesing was purchased in 2006 by one of the largest Dutch media groups- TMG (Telegraaf Media Groep)- ensuring for its future growth, a strong foundation.
Because of our peerless match of enthusiasm and expertise, Keesing has become the largest publisher of puzzle magazines in Europe. In keeping with our growth, we will continue to offer and develop a wide range of puzzle magazines in the Netherlands, Belgium, Denmark, Germany, France, Spain, Italy, Sweden, Norway, Hungary, the United Kingdom and beyond. Our several decades of experience in the field of puzzles and publishing enables Keesing to continue expanding its markets, both in print and digitally.

So addictive! The level 3 and 4 puzzles are too easy for me, but level 5 is perfect. Next time I'm going to try a level 6 or 7. It's been great to move up the levels when I'm ready.
At first I was sceptical about doing Sudoku's on my tablet, but now I don't do them any other way. Erasing numbers is so much easier now!
This app is great! I've been doing Sudoku's for a long time on paper, but I must say that the digital puzzles are much nicer. I especially like the sound effects. Thanks!
