Elevator Pitch
Sudoku! Windoku! Battenburg! Anti-Knight! Renban! German Whispers! …
And a Regular Expression wizard who solves them with arcane incantations.

The first time YAPC was in Houston I showed how we can solve Sudoku puzzles using regular expressions.
Now that YAPC^WTPC is returning to Houston, it is time to revisit the 2007 talk. The world of Sudoku has moved on. Beside regular Sudokus, there are nowadays a lot of variant, using additional rules. For those who missed part I back in 2007, we will first show how to solve normal Sudokus using regular expressions, then focus on several variants, and generate regular expressions for them as well.
Disclaimer: do not try this at home, unless supervised by a regular expression wizard.
