Re: Wrong Puzzles? [WSC 2011]

If I 'ruled the world', my current thinking is that the World Puzzle week should be organised roughly along the lines of: -Monday: World Sudoku Championship, 3 hours max (not necessarily in one go!) of classic Sudokus; World Tapa Championship, 3 hours max (not necessarily in one go!) of classic Tap...

Re: UKPA Puzzle Championship 2014

Congratulation James, fantastic performance! Interesting thoughts about the last puzzle. You described openings in the right way. Maybe in this most important solving phase well-known "trial and error" method is the fastest. I might add if you try to paint in black R7C1-R7C2, you will get full 5th a...

Since last year 24-Hour Puzzle Championship did not take place, I was hoping that this year will be at least two such events. :D

Re: UKPA Beginners Contests

I think Anurag has right. Puzzle 1.3 goes to double solution in top right corner. Number 8 can be reached in two ways, but the solution key is the same. I noticed this during the solving and lost some time here.
