35 years old, I'm a Swiss trumpet player who got lost in the world of sudoku. I discovered variants in 2009 and it became an obsession for me, so when I don't have my trumpet in my hands, I like playing and creating sudoku ! You can find some of my creations on my blog: Variantes de Sudoku
My interest in logic puzzles dates back to 2003 when I came across a magazine called Breinbrekers. I was a fan of all the different logically solvable puzzles immediately. I roamed the internet to find more of these puzzles and found an older Dutch and US puzzle championship online, again with interesting puzzle types. When the editor of Breinbrekers asked people to send in their own creations, I made two of my favorite variants, namely an ABC and a scattered sudoku (by then it was still called numberplace). I found the first the most interesting in that older Dutch championship and the second the most interesting in that older USPC. To my suprise both of my puzzles were published and both were followed by many other puzzles over the years. Nowadays I still make puzzles for Breinbrekers, and also for a Dutch and a German sudoku magazine and for the Dutch and German sudoku championships. Next to that you can try my weekly Friday-noon-puzzle at Logic Masters Germany. Most of the puzzles there are for leisure solving; they are a bit too hard to use in a timed test.
Because my first self-created logic puzzle was a scattered sudoku, my first sudoku test here at Logic Masters India also contains some variants based on this type. The test will be caled 'Shapes and Sizes'.
I have been making puzzles for 5 years and I started to focus on solving in the last 2 years. I am the editor of Akil Oyunlari puzzle magazine and we have published several books including logic puzzles. Inventing Tapa puzzle type and organizing OAPC series are the most valuable works I have done among these.
I was introduced to WPC style puzzles and sudoku in 2005 and got a chance to represent India in the WPC in Hungary. My interest in solving puzzles was overtaken by my new-found passion for creating puzzles. I have authored puzzles for the Indian Puzzle and Sudoku championships for the past 3 years and also the WSC in Goa. I wish to get back to participating soon and build upon my sole participation at a world championship.

I have represented India in WPC 2008, 2010 and WSC 2009, 2010. I enjoy creating puzzles and hope to organise a WPC/WSC in India some day.
