Gardenscapes-First of all, clear the field of crates and portals of chains. The fewer obstacles are on the field, the faster you can collect the glasses. Use bombs to remove the chains from the portals.
Remember that only two glasses can appear on the field simultaneously, and new glasses will appear only after you collect the previous ones.
Try to explode power-ups together to get the Rainbow blast faster. Don’t forget that if you match two Rainbow blasts, the whole field will be cleared from the pieces and one layer of obstacles.
