So happy to have found this! It fixes the "problems" with the original from Roman MaŔek. And when I say problems, I mean that over the years the Android OS broke backward compatibility and you could no longer get to the menu. I don't blame the developer at all for this, but I'm thrilled that someone has taken it up and modernized it. Thank you!!!

The latest update changed my customised colours. As somebody with poor vision, this is a terrible experience. Made the game unplayable for me. As much as I've tried, I cannot restore the colours to how I had them. Really poor move from the devs on this one

I have been using this app for about a year without any problems, however the latest version 4.4.1 has totally lost the 10,000 games that I was playing (1389 played). Error: Could not find puzzle in the database. not a good experience. using the RESET ALL option does what it says, and the unfindable puzzles are again playable (until the next forced upgrade, no choice to opt out)
