Being a mathematician and IT-consultant, inventing new puzzle types and implementing them as an app or web page is my passion.
All puzzles on this website are suitable for playing on any device: desktop, laptop, tablet or smartphone.
Currently you can find 7 of my puzzles here, but more may be underway.
Pullox is a slide-and-fit puzzle, whereas Diagonizer is a sudoku-like puzzle, but with a diagonal twist!
Flipit will require you to find and flip a selection of cells as indicated by counters.
Jump is like the well-known 15-puzzle but with different rules: instead of sliding you have to jump to the solution!
Turnit and 3Turn are like Rubik's Cubes, but these ones are limited to two dimensions.
Finally, in Rokrusi you will see how the familiar noughts and crosses can be used in a totally new puzzle ...
All puzzles are solitary puzzles, but you can beat other players by solving the puzzle in less time.
Earn eternal fame by taking the top position in the list of best times for as many puzzles as you can!
But, most important of all ...
