The goal is to remove all the colored bubbles. When all bubbles are removed you advance to the next level. The game has three modes; Normal, stress and Clean.
Normal Tap the screen to make the bubble at the bottom of the screen shoot towards the point you tap. The more bubbles of the same color you hit, the more points you get. If you don't manage to hit two or more bubbles of the same color, it counts as a fault. After a number of faults a new row of bubbles will appear. The remaining numbers of faults will be shown as small white dots at the bottom of the screen. If you manage to remove all the bubbles, you will be awarded a bonus score and get to the next level. The game ends if a bubble reaches the white information line at the bottom (but you can retry the level unless you have retry sat to "never").
Stress In stress mode there is a timer bar constantly decreasing. Each time you pop some bubbles, the timer will increase a little. You need need to be fast, and keep popping bubbles rapidly to keep the timer from becoming empty. If it becomes empty, a new row of bubbles will appear.
Clean In clean mode there is no bubbles to shoot. You must touch the bubbles (groups of two or more) to make them pop. It might sound easy, but watch your popping, or else you will end up with only one bubble of one of the colors. If this happens, it is game over.
Mode - chose between three different gamemodes, Normal, Stress and Cleran. Se above
Difficulty - Four different difficulties. The difficulty is defined by number of colors used, numbers of faults allowed and initial number of rows og bubbles. For Strss mode, the speed of the timer is also affected.
Endless levels - With endless levels off, the game stops after level 40 and any highscore will be reported to Game Center if enabled. With endless levels on, the game can continue forever.
Progressive levels - With progressive levels off, the difficulty is constant. So level 40 is as hard as level 1. If progressive levels is on, the early levels are easier, but the game gets progressively harder as you get to higher levels. Progressive levels on is most commonly used together witch endless levels on - for those who have found a satisfactory level of difficulty and just wants to play on and on.
Retry failed level - With "Never" the game ends when you fail a level, and you start over on level 1. This can be used for competitions. With "Always" the game automaticly restarts a failed level, resetting the score to what it was before that level was attempted. Note: "Ask" will quite simply ask you whether to restart or not:-)
Tilt'n'Shake - With this option on, you can tilt the device to move the bubbles. You can also shake the device to rearrange the bubbles, but this will add more bubbles.
Style - Just changes the appearance of the bubbles. This does not affect the gameplay.
