User reviews

Bigger font size for oldies

Like this app a lot, as it has very varied topics. Good for older generation to keep the old grey matter in tip top condition.
However (in my opinion) I would prefer the text to be bigger and / or darker as the above mentioned oldies do not have the eagle eyes of their youth.
Keep the puzzles coming, please.

Loving Logic

Fun logic games

Get it right

I love logic grid puzzles, and it seems as though English was not the first language of the puzzle creators. That’s fine. A MAJOR PROBLEM is the clues, a few of them, do not match what the authors claim is the correct answer…I just finished the Rich Boys Club puzzle, and one of the clues mentioned “…$500 less than…”. Not true. I was marked correct on one person but the other had a difference of $1000, not $500, which defeats the game’s purpose.

Challenging puzzles, but…

Boxes are too small so you must be careful when checking a box. There are not that many free puzzles compared to other logic grid puzzles. It would be nice if players could put a line through the clues already solved.

Logically sound

I enjoy a logic puzzle and found these great
