I own the game and have been playing it for few days, opened it today and it showed me a page asking me to buy it again even though I own it on Steam. What a scam Edit: it is working fine now, not sure if that was a bug. Keeping the review for now, will remove it if I don't encounter other bugs until I finish it

A classic, but still just as enjoyable

Not much to say here. It's literally just Sudoku. The UI is clean. Accessibility options are available if needed. More than enough puzzles if you include the DLCs. There are a select few puzzles though that have incorrect difficulties (Medium #57 for example) so be warned. Rating: 3.5/5.
