Definitely a challenging one! Once you get the hang of it, though, it’s a fun and worthwhile alternative to traditional Sudoku.
Great user interface. Handcrafted puzzles. Hints that actually teach. Six levels of difficulty. Themed weekly challenges. Every control a killer sudoku player needs including state of the art killer calculator. Very reasonably priced and the free version has minimal amount of ads.
Best killer sudoku app hands down!
Love this game but it keeps crashing.
I love all of the sudoku versions by Logic Wiz. Definitely worth paying the very reasonable 1-time fee to get rid of ads. Puzzles are appropriately challenging on each level. I like most of the variants too. Those I don’t like can be filtered out so I don’t have to play those games where they are primarily featured.
This app gives you EVERY option for pencil marks, color shading, checking … you can really play Sudoku the way YOU want to. Thanks Logic Wiz!
