We are a group of researchers at the Center for Computer Games Research at the IT University of Copenhagen.
Adaptive Sudoku applies an approach called Bayesian Optimization to model the time it takes you to solve differently challenging sudokus. If you want to find out more about the technology behind it, read our paper.
We collect anonymous data about which sudokus you solve and how long it takes for you to solve them. We do not collect any personal data.
