iGuessColor app for iPhone and iPad

iGuessColor is a simple game but not easy to win. In one turn, you need to brainstorm to predict the right color. Guess Color help you improve your logic thinking. Here are the rules:
The colors need to be guessed are on top. Player have 9 turns to guess the right colors and position. In each turn, player have to choose 4 colors on the right. After each turn, there are 4 hint colors for your guess result on the left:
- Gray : right color but wrong position
- Black : right color and right position
Notice that the position of hint colors are not the same as the order of your guess. At one turn, if you choose the right colors and right positions you will win. You will be the loser if you need over 9 turn to guess.
