Sudoku (Logic9) workshop

I am giving a 1.5 hour workshop at Bishan Community Club on Tuesday 18 December at 8 pm. If you are interested to attend, call the Club at 6259 4720. The fee is $5 only. You can pay on attendance at the workshop.

Special: You can buy 4 sets of puzzle books at a discounted price of $10 (normal $20).

If you are 40 years or older, you can register at the workshop to take part in the national Sudoku Challenge. Attractive prizes can be won. If you practice using my tips, you have a good chance to win the competition.
