Fantastic game, maybe too hard I played much of this game on my desktop, but it got very difficult to solve may puzzles. The concept and execution is impeccable. I would not recommend it for anything less than a decent tablet. Graphics would be way to difficult to see on a cell phone. I want to play it over on a portable device with the knowledge I gained from previous play, which was many hours. Requires great logic combined with imagination. If you struggle with the demo, I wouldn't recommend the full game, even at the very reasonable price.
Crashes on startup I've played the game briefly on pc and loved it so I downloaded this for my Samsung Galaxy NotePro 12 running Android 4.4.2. Crashes 99/100 times on startup. The one time I managed to run it, I got to the last tutorial level before it crashed again to never load again without crashing. I've re downloaded and reinstalled, but still not working. I'll gladly change my review to 5/5 once this gets sorted out.
Was crashing, now fixed! Brilliant game. Was crashing on my new Galaxy Tab Pro 10.1 (while working perfectly on my Note 3 and older Note 2) but the latest update fixed everything. A truly brilliant game that I come back to time and time again.
Best puzzle game ever I've played over 100 hours, and completed all levels on three devices now. Would have been worth my money at $30. Very challenging pure logic game with an excellent difficulty curve!
One of my favorite games of all time This game is one I love going back to. There is such a sense of accomplishment when you improve a system by even just a few cycles. *update has fixed Samsung loading issue. Works fantasticly again.
Programming as a game Love this game on the PC so I had to get it for my tablet too. What makes it good are the simple rules and open-ended solutions to all the puzzles. Only wish I could use keyboard shortcuts, or at least more easily place instructions on the board. All the instructions/speed controls are at the top edge of the screen and are difficult to select on small screens.
Fixed a crash when loading on newer Samsung devices.
