Impossible to complete 1574

For some reason level 1574 seems to have more marshmallow squares and sealed blocks than when I've checked online on what people have posted on YouTube which has MUCH less marshmallow squares and sealed blocks. Also my bot that I'm playing against is so stupid and will make stupid moves. Help me pls. I've been at it for months. Have tried to utilise 2 of the boosters with the hope that if I combine the 2 it will.blow up the marshmallow and sealed blocks. But the one time I got then aligned. The stupid bot used 1 of the boosters for a stupid move.
