Re: UK Puzzle Championship 2018 / WPC Qualification

Hi Adam, Aside from some obvious initial moves, the starting point I used for the Fillomino during the contest was to count the given 4s. There are plenty of them, and only 5 possible different shapes. You can work out which ones connect, and make some deductions about which shapes can or cannot go ...

Re: UK Puzzle Championship 2018 / WPC Qualification

I also found the mirror terminology confusing. In my reading of the rules, I think you can, instead of thinking about mirrors, simply say that the "mirror clues" refer to the number of intersections at which the laser turns instead of going straight. This includes at the boundary of the grid. The on...

Re: UK Puzzle Championship 2018 / WPC Qualification

One additional question from me: in Set Square, will the numbers outside the grid necessarily be integers? If so, is it valid for intermediate results to be non-integer (e.g. 2 / 6 * 3 = 1)?

Re: UK Puzzle Championship 2018 / WPC Qualification

Am I missing something in the rules for Fillomino (Different Shapes)? The example puzzle seems not to have a unique solution - one can replace the 4 and 3 polyominoes from the lower-left corner of the given solution with a single 7 polyomino without appearing to break any of the constraints. I think...

There's currently a discrepancy for the points value of the Shikaku between the instruction booklet (15pts) and the answer page (14pts).

Re: UK Sudoku Championship 2018 / WSC Qualification

Thanks very much! When I submitted the Thermo Sudoku with 15 seconds remaining, I didn't realise just how important it would be!

Re: UK Sudoku Championship 2018 / WSC Qualification

As regards the bonus points, am I correct in my understanding that a solver who submits correct solutions to 15 puzzles and also makes a random guess at the 16th will score the partial bonus of 2 points per minute saved, but a solver who submits 15 correct puzzles and makes no attempt at the 16th wi...

Hello from a long-time enthusiast!

Well, hello there! My name is Sam, and I've been solving Sudoku in one form or another since I, like many, found one in a newspaper in 2005 and got hooked. I'm a total stereotype - a geeky computer programmer with a maths degree who loves Sudoku - so feel free to blame me and my ilk for some of the ...

Re: UK Puzzle & Sudoku National Championships 2018

Thanks to all involved in running these competitions! I'll be a first-time Sudoku entrant this year, the previous two contests having unfortunately fallen during weekends when I was on holiday or disconnected from the internet. I've immensely enjoyed the puzzles from previous years and look forward ...
