    So like the title says, it's infinite sudokus. Which is more or less accurate, duplicates will occur approximately every 1.8 million sudokus in a given direction. The idea is you solve a puzzle, and it reveals part of a map which is populated by amusing sprites selected by me and my kids. The outside corners of every solved sudoku are like a seed for the neighbouring sudokus. And of course you can solve one-off regular sudokus, and there's a sudoku of the day at each difficulty level.

    Fun features:

    • solver for sudokus
    • actually helpful looking hints (you can ask for a hint and it'll tell you the name of the technique but not where it is, and if you want more it'll show you exactly where the technique can be applied with illustration)
    • pretty good lessons that teach some of the medium and difficult techniques, but not the crazy stuff that requires multiple sheets of graph paper and a box of crayons
    • annotating tools beyond the regular pencil marks
      • simple colouring that displays locked pairs and lets you do alternating colours on the resulting graph
      • pair and triplet identifiers
      • multiple digit highlight
      • candidate trials so you can guess and check down a chain until you see a contradiction and revert at any time

    Any feedback is welcome!
