This game is so much fun. It is definitely a brain teaser, but it is so much fun and is perfect for killing time. I wish there were more levels and I hope they are making more. Otherwise, this game is great!

This game makes zero sense. The tutorial explains nothing. There's literally no instruction on why some square turn to an X and some to an O. I've figured out (on my own) that the goal is to have the blocks match the top. So if there are two green Xs and two red Os, you need to turn two green boxes into Xs and two red boxes into Os. But there's absolutely no guidance on how to control that. I'm just randomly swiping to figure out what the pattern is.

At the top of the screen you'll see X's or O's or both. These come in either red or blue. For every red X for example, you need to end up with that many red X's after swiping all the boxes on the screen. For every blue O you would again need that many blue boxes showing the letter O after swiping all the boxes. So in other words, you'll need to duplicate what's shown at the top at the screen, by swiping boxes on the lower part of the screen. If after all the squares have been swiped and you've managed to end up with the same pattern at the top of the screen, you clear the level. Now just a few more details. You can swipe squares left, right, up, or down. With each such swipe, you create a ribbon that's drawn in the direction you swiped. Note, ribbons can not cross each other. Here is how you can to place X's and O's. The color of the first box you swipe will become a O. If the ribbon you create runs into another red square, then that will also become an O. However, if the ribbon run into a different color then the color of the square you first swiped, then that square becomes an X. That's it folks. It's fun, relaxing and sometimes makes you think. It's just not enough puzzles to enjoy. The first 32 levels are free, then it will cost you 99 cent for each of the two remaining 32 level packs. Try it, it's free to start.
