Okay I didn't realize it didn't give a clue if there are errors! That makes total sense :) I really love this app. I have spent way more hours than I care to admit working my way through the levels. My one complaint is on some of them there is a glitch when I try to get a clue, I get charged the 10K coins, but it tells me the number of errors that I have instead of the clue. And it does it over and over no matter how carefully I am touching the screen. Other than that, it's perfect!

Great app. Tons of free puzzles and the upper levels are very challenging. Def worth the download and if you can totally buy the extra levels to support this gem!
★★★★☆Rochelle Weidensee· Jul 26, 2021
Had 15 puzzles left in level 13 when the level would no longer populate on my tablet. The same thing happened with my Android phones with level 13. When I reinstalled the app on my phone I lost all the completed points and puzzles, but was able to open level 13 again. Puzzles are more challenging than many other apps, which I like, however some repeat. Other than the glitch at level 13, I prefer the format and options over most Kakuro apps.

UI for number control is not comfortable & makes proper loading instead of just black screen, it reminded me of a bad experience when my phone broke.

Love the game - it is great. Would love the continue playing, and you only get one free hint a day and no way to earn free HINTS from watching ads. I am not paying for hints.

Following on from your comments. This is on by default. How do I turn it off? Comment on feedback: That's not what I (and many other people) want. We're not children. I don't want flashing lights if I make a mistake. Part of the point of games like this is to test your mental agility. Not to let the app do the arithmetic for you. This should be optional.
