Are there more coming?

I’ve tried many logic puzzles, and this one works the best for me. I’ve done all the free ones and purchased puzzle pack one. I see more puzzles have been requested for a long time. That’s why I gave only a four star rating. I sure hope more puzzles will soon be available.

Love this app! Well designed.

Well worth the $1.99 I paid for all the fun I have solving these puzzles. I really like the way this is set up and the ability to push a button to fill in the column & row Xs after I complete each clue. Also like the option to see if so far my answers are all correct. Can the developers find a way to present the kind of logic puzzles that aren't on a grid? I want to learn how to do those. But the grid kind is my favorite!
The mechanics are well done and the clean look is appreciated. I also like how the section you are working on, zooms in for more accurate placement.

The review complaining that this was not free needs to google AppSliced to put in an alert for Apple app price drops and then wait to see if it does drop instead of complaining about paying. Geez. It is tough enough finding this type of puzzle as an app, don't ruin it for the rest of us. Go take a nap instead!

What is wrong with this app? Nothing!!!

I’ve been doing these types of puzzles for over 20 yrs and happen to enjoy doing every single puzzle that are FREE and in the package you can purchase (wish there were more though).I always take my time doing them, what’s the rush? The design is fantastic & works extremely well on my iPad. I have absolutely NO problem marking any boxes whatsoever.
