I'm still stuck!

What confuses me is that slice will sit on the ledge and not drop to board #2 but yet the pieces would if it weren't a slice. I've broke the top bricks, completed right tart, alternated slices between bottom and right tarts but completing the right tart first, put a couple slices on board #2, move 1 slice to complete bottom tart, some fall to board #2 but a couple fall from the left. Board #2, after bottom tart is completed and breaks top bricks I may be left with 1-2 slices. I'll create spoons and clear 65% of area but yet no new pieces. I've also tried to use every slice that falls on board #1 but once that last tart is complete more slices fall and stay. This is utterly ridiculous...... especially when I'm at the top of the day world AGAIN (level 1045) and waiting for them to build more AGAIN! I guess they only build 20 levels at a time.
