I absolutely love this game. This game is so addicting. The "Challenge Mode" is really interesting to play. And its really challenging, because I have to pot only black coins. And the "Time Trial" mode is also addicting to play, because when I pot more than one coin one after one, my multiplier increases and which boosts my score and time. I can submit my highscore to open-feint leaderboard and its really fun to unlock the achievements. Really worth to buy.
