Good Game :)

Thanks for making this game :)

Yes!!!

This game is very very entertaining. The puzzles are very challenging on the higher levels. My brain is working so hard and is starting to overheat and there is now steam whistling right out my ear canals. I’m very excited to play nr.2 the second puzzle to this spectacular app. I sure do hope I find a female of my species soon so I don’t have to write long reviews or look long and hard for games like this one that excite me in more ways than one.

Fun and addictive

I really enjoy this puzzle and spend a lot of time noodling over some of the challenging levels.

Brilliantly Addictive

This game makes me keep wanting to play over and over again. Very simple and easy to learn, but has a great learning curve for mastery and recognition of patterns and strategy. The ads are much less frequent and intrusive than I am used to with free puzzle apps, being skippable after 5 seconds.

5/5 wholly recommend.

Good puzzler, muddied by ads

I understand ads help you make a little bit of money, but it's a bit overkill with the banner on the bottom AND the video advertisements. Just stick with one or the other, please
