Step-by-step solution

Quick answer
  1. 1) Leave the far-left column and its bait Yellow marble untouched, and pull only from the unchained center and right columns to grab the accessible Cyan and Pink marbles.
  2. 2) Get rid of the front Cyan and Pink Boxes first, which shifts the bottom board upward and ushers in the opening wave of Mystery Boxes.
  3. 3) Once the front Green and Red boxes (or revealed Mystery Boxes that ask for those colors) are live, begin tearing apart the giant 3x3 Green and Red blocks jammed across the center of the Top Tray.
  4. 4) Against the Mystery Boxes, draw only the Top Tray marbles that line up with them right away, and never take a color hoping its box will show up soon.
  5. 5) With the textured blocks gone, dig straight up the middle of the board toward the Orange Key at top-left or the Purple Key at top-right, choosing the fastest column based on your active Mystery Boxes.
  6. 6) The instant you are able to slot a Key into a matching Box, go for it, because clearing that marble shatters its corresponding lock.
  7. 7) When the first chain breaks, use the surge of newly released marbles to quickly knock out the remaining Mystery Boxes, and tap the bait Yellow on the far left once a Yellow Box finally shows up.
  8. 8) Push up the fresh routes that open toward the second Key, drop it to shatter the final chain, then sort the leftovers to finish.
