Steam Balls HD is a match 3 puzzle game for the iPad where you have to get a horizontal match of 3 balls of the same color. On the bottom of the screen there are 4 scales and each balls have different weight, so the balls on the heaviest will drop to the bottom. So it really depends on the balls weight on where they drop and as the time goes by you keep getting busier and busier.
New colors are also added as it keeps getting difficult. Aside from the mechanics, the game has really nice graphics, and the background seems really cool because of the wood design. The balls spin really smoothly and realistically and I really recommend this game for puzzle fans.
