Step-by-step solution
- 1) Take the loose Orange pieces in the Top Tray's tight center strip and feed them into the front-left Dark Green receiver, as each fill lowers the giant cover counters.
- 2) Leave the Yellow and Purple pieces gathered at the Top Tray's bottom untouched, because their receivers sit hidden behind the Dark Red and Orange boxes.
- 3) Use the outer flanks to work on the Light Pink and Dark Brown receivers and earn extra fills.
- 4) As soon as the fifth bottom receiver empties, the left cover splits apart and the whole left half becomes open.
- 5) With the front gone, the Yellow, Dark Red, and Purple receivers turn live, so finally dump the Yellow and Purple you skipped to clear the Top Tray's bottom row.
- 6) Rely on the Dark Brown pieces that surfaced in the upper-left to cover the right-side brown needs, and push three more fills to hit 8 and drop the right cover.
- 7) With both covers gone, steer clear of the Orange and Red midgame ambush — peeling deep layers shows long Orange and Red runs that jam the belt if you over-pull.
- 8) Give top priority to the Dark Blue receivers rotating to the front, handle the Light Greens and Light Blues last, and hold the belt to just one or two stray marbles as you clear the last clusters.
