Very fun and quick game. The app listing says their are ads and in app purchases, but I never ran into one. The game consists of a series of different puzzles using a dozen or so different mechanics and each is presented as a unique setup. It was 50 or so levels in total and was an hour or so of entertainment. The short levels made it a great time filler in the deadspace between meetings today. I can't see it offering any replay value, but I'll probably check out the dev's other games.

Very enjoyable. Challenging puzzles, just difficult enough to be interesting, but not frustrating. Watch a short ad for a hint. Multiple hints available each level. Some are less than helpful, but just ask for another hint. Easily completed in one sitting, but still very enjoyable. Just go download the next color when done. Unique puzzles every level. Some are similar, but include a new twist. I definitely recommend trying these out.

Really not sure why people have such a problem with this. The levels are each unique and challenging, but not "broken". None of these levels require hints to be solved, you can figure most of them out with a bit of experimenting. The ads are non-intrusive, only showing up when you tap the hint button, and most of them are skippable after 5-10 seconds. If this game is challenging for you thats fine, but don't rate it poorly because you needed a few hints. I really don't understand the hate.
