Fun! Thought Provoking! For everyone!

This is one of those thought provoking games that you can get lost in! It's easy to overthink, but almost impossible to put down. This is the "go to" game whenever anyone picks up my iPad!

I've read the interview of another interviewer which states that he doesn't quite understand the pull of the game and referred to feeling the same about another game "Zendbound". As an artist/photographer married to a Ph.D level engineer, I found that my husband saw the world as numerical, primary colors and basic shapes. Initially, he would a also have not been interested in this game. But, through interactions with my work, he became interested in the "chaotic" nature of my thought process, which he found as not only fun, but opened additional areas in his mind and profession. If you are numerically inclined, begin playing this game as a simple logic puzzle, red plus blue equals purple or 1 + 2 = 3. I think you'll find it will add dimension to your daily life. You will see that purple is no longer just purple, it's a combination of colors. It's exhilarating!

I hope they continue to add levels. I highly recommend it for all ages!! And don't be surprised if your child surpasses you!

It's just ok.

The object of the game is to change your clear orb to a specific color by absorbing other orbs around you. Some colors can be mixed together (primary), some can only be absorbed by matching the color. It is challenging as you go along, but the game had good instructions.

I am not crazy about this game so far. Maybe it gets better at higher levels, but it's just not a fun game for me. The graphics are good but basic; other reviewers say it's "minimalist". However you describe it, it's not what I expected. The game play is not interesting to me. I don't remember what it costs, but if it's more than a dollar, it's not worth it.

That's just my opinion. I read the other reviews. Most are really positive, so it's obviously not a bad game. Just not interesting to everyone. (I never understood the appeal of Zenbound either, and it is one of most loved and highly-rated iOS games ever.)

A game for the wise

This isn't a typical guess and check puzzle game that you find on the App stores among us; this is an honest to goodness logic puzzle that requires you think 3, 4, 8 steps ahead if you actually want complete the game in a timely manner. Just checked the game center and it tells me I completed the game with 392 combinations. I'm betting the minimum number of combinations is around 320, and probably 2.5 hours to do so. (There are currently 72 stages with average 5 objects to it (350 moves), so that may be underestimating it)).

Hope every one enjoys and I'd love to hear more from others about how many color changes it took them to complete the game (It's in game center).
