Step-by-step solution
- 1) Tap the solid Dark Blue block at the lower-right of the tray so the rush of Dark Blue marbles sorts and clears the top layers of columns 1, 2, and 4.
- 2) Then tap the solid Green block beside the empty space at the lower-right to sort straight into column 3 and clear that Green bottom box.
- 3) With the Dark Blue and Green solids gone, grab the loose Dark Blue marble in row 5 on the far right to wear down the rest of the Dark Blue receivers.
- 4) Skip the Purple and Red solid blocks on the left for now, since no Purple or Red bottom box is active yet.
- 5) As the lower layers reveal Red, Yellow, and Purple, play the loose Yellow and Light Blue pieces only when a matching bottom box is open, and keep belt space for the x2 Multiplier doubling.
- 6) Tap the solid Purple block on the bottom left once column 3 exposes Purple, then watch the first Surprise Bag dump its single-color Light Green flood.
- 7) Let the matching Light Green bottom boxes rise to the top and automatically suck up the Light Green marbles filling the belt.
- 8) Release the solid Red block only when a Dark Red receiver shows up in column 1 or 4, beware Surprise Bags sliding over the Multiplier Gate, and feed the stray Light Blue marbles down one by one to finish.
