LMI contest: Sudoku Deja Vu

[david mcneill]

Just letting you know about a (hopefully) fun contest on Logic Masters India this coming weekend set by yours truly. I would encourage you all to have a go. It's slightly different from the usual.

Enjoyed this - just the two of us from the UK having a go so far, but definitely worth a go!

Aside from my frustration (at myself!) for being extremely slow to spot the Deja Vu rules (I spent approximately 30 of the 90 minutes not actually solving sudoku...), thank you David for some lovely puzzles and a fun contest!

I'm especially impressed by how the Deja Vu concept didn't detract at all from the quality of the puzzles - the 5 normal grids stood up very well as puzzles in their own right, and if they had appeared as standalone puzzles there would be nothing about them to indicate that they were hiding a secret constraint.

I thought that the Diagonal and Anti-Knight pairs were particularly aesthetic and pleasant to solve.
