Fun, easy and relaxed pastime.
Know where and when to release the ball so that it reaches the goal.
If an obstacle wants to get in the way, intervene with precise touches. But be careful! If you don't act wisely, touches can be more of a hindrance than a help!
And who knows if the obstacles contribute to the path to the goal?
Have fun! Score goals, collect diamonds, win or buy items, but don't underestimate the spikes, as your ball may burst!
