User reviews
It's like therapy.
This fun little game is easy to play with no obnoxious pop-ups or pointless flashy graphics. The puzzle games have wonderful range and I can find a level for each that I find challenging. It's so nice to just relax with a logic puzzle!
Perfect
Many great choices of games ranging from classic to new, and all without the constant interruption of irritating ads over and over. I've had the game for years now, and never get tired of it.
Wonderful apps. Tons of different puzzles with no ads at all. Thank you so much.
One of the best puzzle apps I have ever used. There are no ads. The controls are a good, my only problem with them is that you have to use two fingers to move the screen around while zoomed in, but I am getting used to it. It has a great variety of puzzles and is truly a joy.
