Marble Sort Level 666 is a puzzle that tests your patience. The board starts with many colors visible, but most are not ready to be used. Your main goal is to clear the front row of Boxes that need Light Green and Orange, while avoiding the Yellow and Purple marbles that sit in open areas. If you tap those early, your Conveyor Belt will fill up and you will lose.

The layout has a central Panel marked with a '4' that blocks the middle area. Two yellow Lock bars stand vertically on the left and right sides. The left Lock holds Pink, Cyan, and Purple pieces. The right Lock holds Pink and Light Blue pieces. In the four corners of the Top Tray, there are Arrow Boxes: Cyan in the top left, Light Green in the top right, Yellow in the bottom left, and Pink in the bottom right. The bottom row of Boxes starts with Light Green, Orange, Orange, and Light Green from left to right. Behind those, you will find more Orange and Light Green, and eventually White and Blue.

Marble Sort Level 666 Walkthrough

The front row of Boxes demands Light Green and Orange in this order: Light Green, Orange, Orange, Light Green. You must fill these four Boxes to drop the center Panel. The available Orange pieces are located just below and to the right of the center Panel. The Light Green pieces are near the bottom center and the right edge. Do not tap any other colors until these Boxes are done.

The main trap is the Yellow and Purple marbles that are easy to reach. They look like quick wins, but their matching Boxes are buried deep behind the Orange and White rows. If you take them early, they will sit on your Conveyor Belt and block your space. You must ignore them completely at the start.

How to Beat Marble Sort Level 666 — Step-by-Step

Phase one: Clear the front row

  1. Tap the Orange marbles that are below and to the right of the center Panel. Feed them into the two inner Boxes of the front row.
  2. Tap the Light Green marbles near the bottom center and the right edge. Route them into the two outer Boxes.
  3. Do not tap any Yellow or Purple pieces. Leave them alone.
  4. Once the four Boxes are full, the center Panel will disappear.

Phase two: Unlock the side columns

  1. After the center opens, new colors become available. Look for White and Cyan pieces in the middle area. Drop them into the new front row of Boxes that appear.
  2. Now you need to activate the two yellow Lock bars. To do that, you must clear the specific colors that are associated with each Lock. The left Lock requires clearing Pink, Cyan, and Purple pieces that are pinned underneath it. The right Lock requires clearing Pink and Light Blue pieces.
  3. Once the Lock bars are lifted, the large clusters of Pink, Cyan, and Light Blue are free. Prioritize the Pink marbles, because the bottom Boxes will ask for Pink often during this phase.
  4. As you empty the middle and sides, the Arrow Boxes in the corners will slide inward. When they move, sort their contents immediately.

Phase three: Finish the remaining colors

  1. Now you can finally clear the Yellow and Purple pieces that you avoided at the start. Their Boxes will appear in the back rows.
  2. Check the order of the final bottom Boxes. Drop the Red and Blue clusters in the exact sequence they are needed. Do not tap randomly.
  3. Keep at least two empty slots on your Conveyor Belt at all times. This prevents a jam at the end.

Tips & tricks

  • Always scan the bottom Boxes first to know the next color you need.
  • Use the center opening to access colors that were previously blocked.
  • When the Arrow Boxes move, sort them right away to avoid clutter.
  • Keep a mental note of which colors are still locked behind the side bars.

Common mistakes

  • Tapping Yellow or Purple early in the game, which fills the belt.
  • Ignoring the order of the front row Boxes, causing a mismatch.
  • Forgetting to clear the Lock bar colors before moving on.
  • Letting the Conveyor Belt fill up because you tapped too many colors at once.
