Step-by-step solution
- 1) Open by clearing the front row of boxes, which demand Green, Red, and Light Green, and leave the giant 9-marble clusters at the bottom of the tray untouched.
- 2) Grab the lone Green marble resting in the middle-left lane and the isolated Red one from the center columns, then pluck the Green and Light Green singles off the right edge below the Hidden Boxes.
- 3) Feed those selected singles into the active bottom boxes, which lifts the whole lower board and starts ticking down the top-left Tunnel counter.
- 4) Once Dark Blue and Red boxes rise to the front, drop the massive Dark Blue cluster from the bottom left, then send the giant Red cluster down right behind it.
- 5) Let the belt animations finish so nothing jams, and when the counter hits zero the Tunnel spits out a huge block of Pink marbles.
- 6) Because the right-side singles were cleared early, the Hidden Boxes flip over to show a new pile of Light Blue and Light Green spheres, and the bottom row shifts to Pink, Light Blue, and Yellow.
- 7) Release the Tunnel's Pink block into the Pink receivers, then feed the revealed Light Blue and Light Green marbles into their matching boxes.
- 8) Finish by dropping the last huge Yellow cluster out of the bottom middle, shoving any remaining singles down the belt, and easing off on tap speed so the closing animations cannot choke the lane.
