Sudoku: I saw my first paper gamer

(tags game, puzzle, Sudoku, replay-data)

Hudson's Puzzle Series Vol. 3: Sudoku is still occupying my main gaming time. My performance is steadily improving, but if I make a mistake, 10 minutes will be lost due to backtracking.

This time I have completed up to 115 on the normal. Only 25 boards to go on Normal then I will be onto Difficult. I already completed the Silver challenge with ease. It was unlocked at the 70th Normal board. Now there's only Gold and Platinum to unlock.

I improved my best time from 11:03 to 7:53 (yes!). But average time just doesn't want to go under 20 minutes. Last time it was 28:59 @ 41, and this time it is 24:28.

I did figure out a newer sub-strategy involving a row of 3 and non-same row element pushing to the other side to that row. I won't bother explaining it because it's probably a well-known one. Why is it only the advanced techniques are figured out when the pressure is on?

Oh yeah, I finally saw another person playing Sudoku in real life, and elder lady pushing board number 76 in some paper booklet. Heh. I was about to bust my DualScreen/Sudoku demo but my bus stop was next so like I let the paper gamer go.
