This board presents a Lock and Key puzzle where the left side is chained and the key is buried on the far right. Your immediate goal is to excavate the right side methodically, storing only necessary colors on the Conveyor Belt, so you can unlock the left side before the red flood overwhelms you.

Marble Sort Level 641 features a Top Tray split by a green divider. The left section hosts a chained cluster with Purple and Light Blue Tunnels, plus some Orange, Pink, and Dark Blue marbles. The right section is a dense stack of Green, Pink, Yellow, Purple, and Light Blue marbles. The bottom Boxes are arranged in four columns: Purple, Orange, Pink, and Yellow, with a second row revealing Purple, Purple, Dark Blue, and Pink.

Marble Sort Level 641 Walkthrough

The bottom row demands Purple, Orange, Pink, and Yellow from left to right. The second row adds Purple, Purple, Dark Blue, and Pink. This means you must clear Purple and Pink frequently, but you have limited Purple on the right side, so use them wisely.

The critical trap is that the left side looks tempting, but touching it early will clog your belt with unusable marbles, preventing you from storing the colors you need to dig to the key. The key is a Light Blue marble with a golden key icon, located at the top right corner.

How to Beat Marble Sort Level 641 — Step-by-Step

Phase one: Excavate the right side

  1. Drop the Yellow marble from the bottom-middle of the right section into the Yellow Box.
  2. Route the Pink marbles from the right side into the Pink Box.
  3. Feed the visible Orange marbles from the left into the Orange Box.
  4. Clear the Purple marbles from the right side into the Purple Box, but be careful not to overuse them.
  5. Continue digging upward through the right grid, clearing Green, Pink, and Light Blue marbles as they become available, matching them to the appropriate Boxes.
  6. When you encounter a color without a matching Box, park it on the Conveyor Belt to keep the excavation moving.

Phase two: Unlock the key and manage the red wave

  1. Clear the remaining right side until you expose the Light Blue key marble at the top right corner.
  2. Make sure a Light Blue Box is active at the bottom. If not, clear the current Boxes until Light Blue appears.
  3. Tap the key marble to drop it into the Light Blue Box, triggering the unlock and breaking the left chain.
  4. Immediately after, a wave of Red marbles will pour onto the board, choking the Conveyor Belt.
  5. Prioritize clearing Red marbles into any Red Box that appears, and keep the belt moving to avoid a jam.

Phase three: Clear the tunnels and finish

  1. With the left side unlocked, tap the Purple Tunnels to release multiple Purple marbles, but only when a Purple Box is open.
  2. Similarly, tap the Light Blue Tunnels to release Light Blue marbles into an open Light Blue Box.
  3. Match the remaining Orange and Green marbles from the left side into their corresponding Boxes.
  4. Keep the Conveyor Belt clear of any loose marbles, and the board will resolve itself.

Tips & tricks

  • Focus all your taps on the right side until the key is found; ignore the left side completely.
  • Use the Conveyor Belt only for essential storage during the right-side dig, and keep it as empty as possible.
  • After unlocking, feed the Tunnels one at a time to avoid overwhelming your Boxes.

Common mistakes

  • Tapping the left side too early and filling the belt with unusable marbles.
  • Not having a Light Blue Box ready when you tap the key, causing a delay.
  • Ignoring the Red wave and letting the belt jam.
