Game of Sudoku

A data set of Sudoku grids with more than one solution. This was introduced to train on logical reasoning problems with non-unique solutions.

A set of 180,000 Sudoku grids with a variable number of hints from the minimal number of 17 (extremely hard instances) to 34 (easy instances), with 10,000 instances per level of hardness. Training how to play the hardest Sudoku instances is a bit of a challenge.

A set of easy Sudoku instances used in the SATNet paper for training SatNet on how to learn to play Sudoku. The instances are easy (plenty of hints) and it is therefore rather easy to get high accuracy on these. More challenging instances are available in the rrn-sudoku dataset.
