Starting Bubbles: 65
3 holes in the ceiling
Points needed for 1, 2, 3 Star:
70 000, 125 000, 60 000
4 Bomb Bubbles
Doom Skull Bubbles
At level 138 you want to avoid bursting the easy Clusters in the beginning. As you can see in the picture from the upper section at level 138, there are Bombs, that will start their countdown way before you can see them, if you burst the easy clusters right at the beginning. Aim at the crystal bubbles to the right below the first Bomb (the only Bomb you see at the beginning) and remove the upper cluster above the Bomb (GREEN in strategy picture 138) before the “obvious” cluster to the left (YELLOW in the Strategy picture 138).
Avoid bursting the chainlike bubble cluster(PURPLE in strategy picture 138) to the right for as long as you can. Bursting it will make one upper Bomb start it’s countdown.
When you no longer can’t avoid setting off the bombs burst the Bubbles to the left first, then the Bubbles on your right hand.
