Dataset Characteristics

—All puzzles have been exact-deduped and randomly permuted by row, column, box, and digit.
—Each puzzle is guaranteed to have a unique solution.
—Puzzles in the train set are mathematically inequivalent to those in the test set.

Dataset Structure

—Train set: train.csv (3.8M examples)
—Test set: test.csv (423k examples)

Puzzles and solutions are flattened in row-major order. Rating is evaluated by number of backtracks needed by tdoku solver required to solve the puzzle (higher is harder).

Usage Guidelines

1.Train models using only the train set.
2.Evaluate models on the test set using exact accuracy (all numbers must be correct).
