What’s New

Version 2.0

Finally fixed the mute sound bug. Sorry it took so long. You can now listen to your own music while playing the game if you wish. First start the game, tap the Options Button then tap the Sound Button to turn off the sound, now start your own music and finally return to the game.

Found an error

I found an error in puzzle pack 4, number 31. Is there some way to contact the creator to let you know?

It's okay...

... but it took me LITERALLY under 10 to complete the first puzzle pack, thus my freebie was over. I spoze if I downloaded ALL their games I could get an afternoon's entertainment out of it... 😉

So Much Fun

This is a fast-moving game that you can play either when you have just a few minutes or when you have more time. You rapidly lose track of the time when you're playing though :) I can already tell that the original game packs will not last me long, but this developer is great about bringing out additional content.
