The idea is to remove clusters of balls (2 or more) from the screen before the timer runs out. The bigger the cluster, the more points you get.
You have to remove 100 balls from the screen to complete each level. Once clusters have been removed, the balls drop down, and fresh ones appear from the top. If there are no valid clusters, you will be told, and will lose a life (you start with 3, and are NOT given any more).
The timer bar ticks down at a constant rate, roughly 2 seconds for each bar on level 1, and gets slightly quicker at the start of every level. If you run out of time, you lose a life, and the level will restart.
A bonus is awarded at the end of each level for the time you have remaining … do the level quicker, get a bigger time bonus. You are also rewarded a bonus for each type of cluster you remove … the more bigger clusters you remove, the higher the “cluster bonus”.
You have two ways to play …
The quicker, and easier, a simple tap on a cluster to remove it. Doing it this way could lead to mistakes, tapping a single ball costs you five timer bars, but you get the chance of getting a bigger score.
The slower, and sometimes more hectic way, use the arrow controls in the lower part of the screen to highlight a cluster, and tap the “tick” button (which will only become active if the cursor is on a valid cluster). Doing it this way means you can’t make a mistake, but you’ll probably get a lower score!
This game features a “highest world scores” feature (which requires an internet connection, either trough WiFi, or the devices mobile signal). Players don’t just see what personal best they can get, but can compete for being the “best in the world”, or atleast make the top 10. Your own personal scores are shown in a separate high score table, so if you can’t beat the world, you can try to get your own highest score.
