Great brain workout. Small nit. A "positive" dot autofills the "X"s. Later on, you realize it's an error & want to erase by tapping again. But it will also remove ALL of the associated "X"s, too. Even the ones you had put in from prior clues already, & wanted to keep! ("undo" might work if you haven't placed more good markers after your error.) Hints are written kinda mathematically, which gives us numerically disabled players a headache! (Numbers are slow to process in my head.)

Overall, this is a very nice and simple app. Personally, I had to uninstall because the details were too small for me to select on my phone - probably very nice on a tablet. I wish you could edit the layout/size of the clues vs the puzzle sections. However - this is a free app that has no ads. Free does have a limited number of puzzles, but it is a decent selection of 10-30 puzzles in 5 different difficulties with an optional unlimited version. If you like these types o puzzles it's worth a try.

Thanks for giving it a try. Note that you can tap on a row or column to highlight it, and then you can zoom the grid (like a photo) to make it larger. This makes it easier to tap and select. Unfortunately there's only so much we can do with small screens, but we try! Happy puzzling!

Seems to be a popular game template but this one has zero video ads. For that alone it's nice. And then of course the puzzles are very cool and come in all difficulties. From the get go I could solve up to the second hardest levels. The hardest are just extremely time consuming so I don't know how easy they are to solve. But this just shows that the game is fit for any level of player. For me it's just a random find and it's cool. I just got lucky clicking a random game.

What’s new
Tweaked the new crossed-out hints feature so it stays in the same position while the crossed out clue moves to the bottom.
