Great killer sudoku puzzles! I only wish the number input controls could be switched to input by number instead of input by cell, other than that the game is great.

Lovely app, horrible graphics. When a box is highlighted, the 'bold' lines do not allow seeing how many cells in the sum. Concepts have other SUDOKU puzzles whose graphics are great.

My favorite killer sudoku app! I love how it shows you the possible umber combinations for each section, and allowing me to cross out combos that I know won't work. Only thing I wish was that it would have daily puzzles with a streak tracker, and something to show how I compare to other players on each puzzle. Adding events would also make sure I log in daily! Oh, and please allow us to customize our colors 😭 yellow on beige is sooo hard to see

Love this game, but would like the option of a hint on the Killers without requiring autofill. When I've already eliminated most of the extraneous possibilities. Why can't a hint take me from that point, instead of having to repeat every option? When I already have the squares marked manually with everything but what I have already logically eliminated, there should be the possibility of a hint based on my current markings, instead of repeating the obvious & please provide further Explanations!

UI is unbearable Edit for clarity: numbers aren't in a straight line, poor contrast. If it's just a setting, then ok the default is not good imo

My hard puzzle wasn't reset this week. All the other puzzles were reset when I hit the reset button. But my hard puzzle stayed completed. Edit to reply: No, that is not what I'm saying. I didn't get a new weekly hard puzzle. It stayed the same puzzle as the previous week.

Some of the killer puzzles are impossible to solve without hints. It ruins the game. I don't want to risk running into another impossible puzzle, so I won't be playing this anymore. It was fun until then
