Step-by-step solution

Quick answer
  1. 1) Touch the two Purple pieces set on the flanks beside the central frame to fill both live Purple receivers at once.
  2. 2) Touch the pair of red-and-white rocket Boosters over on the far-left rim so they blast clear of the tray, freeing the left lane and uncovering the Pink piece beneath them.
  3. 3) Touch that Pink piece just uncovered at the lower-left corner to empty the opening Pink receiver.
  4. 4) Touch the central 2x2 red frame at its upper-right cell, since a single Red piece is all that is needed to empty the opening Red receiver.
  5. 5) When the second row calls for Red, Purple, Red, and Yellow, draw on the three big Red pieces left inside the blue-striped frame to empty the two second-row Red receivers.
  6. 6) Touch the Yellow piece sitting near the wrap's lower-right area to empty the newly exposed Yellow receiver, then take the final Purple piece from the eastern side to close out the row.
  7. 7) For the following row of Yellow, Pink, Yellow, and Pink, search the lower area and sides for the remaining Yellow pieces, since belt pressure is now very low.
  8. 8) Move the untouched Light Blue and Green pieces off the top and bottom outer rims into their receivers for rows four and five, use the Green pieces at the very top of the board, and hold back Green whenever a Light Blue receiver sits in its path to win.

Frequently Asked Questions

What is the main trap to avoid in Level 721?

The biggest mistake is tapping colors that have no active bottom Box yet. They park on your Conveyor Belt and burn limited slots, so clear the shades that actually have receivers first.

How should I open Level 721?

Ignore the upper layers and aim at the bottom row of the Top Tray. Feed the colors that already have open boxes, then work upward once the lower lanes shift.

When does the midgame color change happen in Level 721?

After the opening boxes fall, the lower columns swap what they demand. Watch for the new shades and only pull blocks that match a box sitting at the front of a lower lane.

Any tip for finishing Level 721 clean?

Keep at least a few empty belt slots before poking mystery or hidden boxes. Feed a revealed color the moment it matches an active box, and fall back to visible marbles when the belt gets tight.
