9 Maker is a fast game. Unless you end up watching all those ads. At the moment, my score is over 1000 and I'm first on the Leaderboard. Fewer than 100 people are currently on the Leaderboard.
I really like the graphics. But the ad watching skews the playing field. When the game starts, the random #s are just 1, 2 & 3. So earning a power-up is not too hard. Once the 5's, 6's & 7's appear, earning a powerup is almost impossible.
