On level 188, you need to adjust your strategy according to the moves available. Clear the honey, but don’t miss out on the opportunity to create firecrackers or larger power-ups. The main goal is to get the Rainbow Blast as fast as possible. To do it, explode several power-ups together.
The Rainbow Blast can be further used on leaves or pears. After you’ve cleared the honey — preferably, with power-up explosions — make sure that your lemonades are in one of the odd vertical columns (1-3-5-7-9-11). This way they will be collected instantly after passing through a portal. Use the Rainbow Blast on pieces that are blocking the exit points on the top of the field.
