Step-by-step solution
- 1) Flick the Light Pink ball resting on the crate's lower-left side and feed it to the far-left Light Pink Box.
- 2) Flick the Light Blue ball under the crate's right flank, then grab the Yellow ball above it and feed it into the third column's Yellow Box.
- 3) Pull the Light Blue marble from the top-left edge to help clear your front-row Light Blue receivers.
- 4) Keep feeding Light Pink and Light Blue, since the entire second row of bottom boxes leans heavily on Light Pink; harvest every reachable Light Pink off the bottom and right flanks.
- 5) Do not touch the left-side Brown marbles or the Orange marble on the top right, or your belt fills with dead weight instantly.
- 6) Once the early Light Pink and Light Blue boxes clear, the new front row turns to Orange, Brown, Light Blue, and Purple, so unleash the left column straight into the freshly revealed Brown Box.
- 7) Collect the Orange ball on the upper right now that an Orange receiver finally exists, then clear the Purples piling on both sides to free up belt space.
- 8) In the funnel phase, leave any lone Dark Pink in the drop zone until its own receiver rises into view, and sort the Light Blues and final Purples so the last boxes pull everything down cleanly.
