Good game and realisation Like this game. But 'hard' is too easy to play because of many 'easy' numbers (16,17 etc). Would like greater fields, harder puzzles. Although game have pretty high energy consumption(works only 4-5 hours on nexus 7). Although I do not understand why there is highscores with fixed scores - 860-864. There is no challenge.
Decent Not overly challenging. Would like bigger, more difficult puzzles. This one has a lot of "given" answers. Scoring seems arbitrary and seems to have no purpose. Program is easy to use, has never crashed on me, and is great for beginner to intermediate levels. Good for a quick mental workout.
Multiple solution games Edited to remove incorrect report of a problem. Interesting and fun game. One thing that would be nice would be to have the annotations be in the order they are written, not numerical order. For example, if two squares must add to four, I would like to annotate them as (1,3) and (3,1) rather than both the same. That way it makes it easier to quickly see what choices go together (more so when there are more squares or more choices per square).
Add timer This is a stellar app with only one flaw: the scoring isn't explained at all. I'd feel a lot better about my score if I knew how it was calculated. Whether or not that is changed, a time would add a lot of replay value. This doesn't mean that the time it took to finish should go to score loop, just that I should be able to see improvement and predict scores.
Good Game My only suggestion would be to give the user the ability to toggle off the green/red answer mode. Seems a bit like cheating. I like the challenge of going through the puzzle and then seeing if all my answers were correct. The red/green indicators spoil that experience.
Fun game Great functionality. A couple of requests I would have are a "clear" button for those occasions when you've just really messed up and want to start fresh. Also would be handy if when you erase a number, the prior notes reappear.
