Puzzles sometimes have multiple solutions, and if you don't guess the apps favourite one, it is WRONG, wrongness is judged by interior numbers, not by fulfilling all constraints. Happens more often in higher levels. Have to solve lots easy puzzles before getting to interesting ones. Controls are clunky, need two taps for every cell, cannot mark e.g. all sixes in one go.
Lame I started playing this last night and I've come across multiple puzzles that have more than 1 solution but it only accepts 1 solution. There's no logic involved it's literally a toss up pick wrong you still end up with a valid solution but nope that's not the valid solution we were looking for.
Fun but flawed game. I like logic puzzles and this one has a lot of potential. However, sometimes logic isn't enough and you have to arbitrarily guess.
Challenging! My cousin told me about a version of this game for Windows phones. I downloaded this version, now I'm hooked!
Fix the bug where there are more solutions, the game just approves one of them, which is really bad.
Fun Once you get the hang of it, it becomes a little to easy, but still really fun.
