Puzzles

I can create and produce a range of Japanese puzzle types, including:

• Sudoku, including all variants such as Sudoku-X, jigsaw/polyomino Sudoku, overlapping Sudoku and any width or height or shape.
• Futoshiki / Hutosiki, at any size, as well as inequality Sudoku.
• Kakuro, in a range of shapes and sizes. Clue run lengths and the difficulty of both the maths and the logic can be controlled. These are also known as cross sums and kakro.
• Hanjie, in a range of sizes and complexities. These are also known as nonograms, griddlers, edel, pikurosu and more.
• Battleships, consisting of hidden ships with a grid with numbers giving clues to their locations - very much like a solo version of the two-player children's game.
• Killer Sudoku - a cross between kakuro and sudoku. Killer Sudoku X also available.
• Slitherlink - build a non-crossing loop in a grid full of numbers
• Masyu - build a non-crossing loop that passes through a set of circles
• Nurikabe - shade in areas so as to create regions of a specified size
• Hitori - like Sudoku in reverse, shade in numbers to make a valid grid
• Hashi - build bridges between numbers without creating any islands
• Other Japanese puzzles - please enquire.

All puzzles are:

• Available in a press-ready vector PDF form
• Available at a range of difficulty levels, at whatever subtlety of gradation is required
• Created with a single unique solution (also supplied)
• Capable of being solved without guessing
• Can be supplied in black and white or colours or in any design variation you can describe

I have provided puzzles to a range of publishers, including books, magazines and newspapers, both in the UK and overseas.

Furthermore I can provide advanced web-based players that require no additional installation on the behalf of users. They can be trialled on my websites at:
