I like the premise but not the execution
Based on the description I thought “oh cool free sudoku that’s ad free, neat!” which this still was. I didn’t expect it to only be one game a day. I feel like the game or the page should have warned me in some way. I also would wish you could maybe play one game of each difficulty per day, because I played one easy game, gotten into a sudoku mood and then got totally sudoku blocked when I wanted to play on hard. Otherwise pretty solid
