Step-by-step solution
- 1) Ignore the Pink and Green clusters parked at the front of the Top Tray and tap the Black marbles so they fill the Black box in column two and expose a Blue box behind it.
- 2) Now four Blue boxes line the front, so tap the lower-right Blue marbles from the Top Tray to start draining one of them.
- 3) Sacrifice a little belt space by dropping the front Pink and Green clusters onto the Conveyor Belt to uncover the second row of the Top Tray.
- 4) Grab the Black marbles from that second row and either hold them on the belt or route them when a Black receiver moves to the front, then send the second-line Blue marbles into another front Blue box.
- 5) Clearing the east side of the Top Tray activates the Tunnel, which spits a set of Pink marbles into play.
- 6) Send that fresh Pink directly into the first-column Pink receiver that just showed up, since the second layer has now revealed Pink, Green and Orange boxes.
- 7) Tap the exposed Green marbles to clear the Green boxes in columns three and four, which pulls the east side of the board forward and exposes a critical Black box.
- 8) In the finish, send the Orange marbles into the column two Orange box, then tap the remaining Purple from the upper and middle rows to clear lanes one, three and four and empty the last Black box.
