However, he is tenacious about mental challenges, asks questions, records answers, and looks for what is missing (or not adequately explained) in everything he does at work and at play.
So clearly, sudoku was a great place to start.
He felt strongly that the joy of solving the more difficult puzzles was compromised by a lack of instructions discussing the importance of recording the ever-changing status of possible answers, not just recording indisputable ones. Further, with no apparent place to record this important information, solvers would have to remember the status of hundreds of tidbits they had deduced already (and if forgotten, they would be consigned to reperforming many of those analyses).
Tedious.
He felt that this unnecessary taxing of one’s memory rather than focusing on the next logical step, quite simply, took the fun out of the game.
Which is why he created Sudoglyphics. Equipped with these simple marks, their placement and their subsequent use, anyone interested in solving sudoku or solving better may do so without backtracking.
Now, he solves the most difficult puzzles (at the back of the best sudoku collections) in twelve to twenty minutes routinely.lihat lebih sedikit
