UK A-team stalwart and all-rounder David McNeill, from Belfast, won the Over-50 category at both events in Sofia last week.
Mark Goodliffe took the WSC over-50 runner-up award.
David is now the reigning World Senior Champion of both Sudoku and Puzzles.
David was already World Senior Champion for Sudoku, having won the 2014 title in Croydon last year.
Kota Morinishi retained his World Sudoku Champion title, while Ken Endo usurped the 10 times world champion, and clear favourite, Ulrich Voigt of Germany, to clinch a Japanese double.
Further results of both championships will be published later now available
. In the meantime, congratulations are in order for David, Mark, Kota and Ken for their titles.
The full results of the 14th WSC and 24th WPC results are available at http://www.wscwpc2015.org/results.php
Team UK finished 8th (of 21) in the WSC and 7th (of 24) in the WPC.
Individually, in both events, all 4 of our A-team players finished in the top 50.
This represents another excellent performance against an outstanding, and always improving, international field. Well done all, especially David with his double title!
