Marble Sort Level 762 presents a board with a large Top Tray and a Conveyor Belt below. The top area is shaped like a central block with two small columns on the far left and right, packed with marbles of many colors. The bottom has four Boxes that need Orange, Green, Orange, and Green from left to right. The main difficulty is the six Locks that freeze marbles, and you must unlock them in the right order to avoid jamming the belt.

The keys are scattered: a top-left key on an Orange/Red marble unlocks a Purple, a top-right key on a Green/Pink marble unlocks a Light Blue, a middle-left key on a Yellow marble unlocks a Brown, a middle-right key on a Yellow/Blue marble unlocks another Purple, a bottom-left key on a Pink/Purple marble unlocks a Light Blue, and a bottom-right key on a Brown marble unlocks a Yellow. Many keys are on colors you don't need, so grabbing them early fills the belt with useless marbles. The smart move is to first send the accessible Green, Orange, and Pink marbles to their matching Boxes, then unlock keys that are on useful colors or that reveal useful colors.

Marble Sort Level 762 Walkthrough

The front row of the Top Tray holds several useful marbles. The bottom Boxes demand Orange and Green in the front layer, with Pink waiting in the second layer on the left. You must fill those Boxes first to create space on the belt, ignoring the easy-to-reach keys that are traps.

The one specific trap is the temptation to release the Brown or Yellow keys early because they seem accessible. Doing so clogs the belt with colors that have no Box to go to yet, blocking your path to the colors you actually need.

How to Beat Marble Sort Level 762 — Step-by-Step

Phase one: Clear initial Box colors

  1. Tap the two Green marbles on the far right of the front row, sending them to the second and fourth Boxes.
  2. Tap the Orange marble that is third from the left in the front row, sending it to the first Box.
  3. Look for a Pink marble in the front row and send it to the Pink Box waiting in the second layer.
  4. Do not touch any Keys yet; you need to clear more space.

Phase two: Unlock the useful keys

  1. Target the top-right Key on the Green/Pink marble. Clear the marbles blocking it (like the Yellow/Blue dual marble) and send the Green and Pink marbles to their Boxes.
  2. When the Key is released, a Light Blue marble falls. Let it sit on the belt for now.
  3. Shift to the bottom-left Key on the Pink/Purple marble. Clear the path and release it, sending the Pink marble to a Box. Another Light Blue marble drops.
  4. Now go for the top-left Key on the Orange/Red marble. Clear the Orange to unlock a Purple marble. Park the Purple on the belt temporarily.
  5. Continue clearing the board, focusing on Green, Orange, Pink, and Blue marbles.

Phase three: Clear the remaining locks

  1. With more space, address the middle-left Key (Yellow) and middle-right Key (Yellow/Blue) as needed to access marbles behind them.
  2. Release the bottom-right Key (Brown) last, as it unlocks a Yellow that you can place later.
  3. Once all six Locks are gone, the board becomes a standard sorting puzzle.

Tips & tricks

  • Always send groups of the same color together when possible to clear Boxes faster.
  • Keep the Conveyor Belt from filling up by placing marbles as soon as you can.
  • Use the belt as temporary storage for colors like Purple and Yellow that you can't place yet, but don't let it overflow.

Common mistakes

  • Unlocking the Brown or Yellow keys early, which floods the belt with useless colors.
  • Ignoring the initial Box colors and focusing on keys instead, causing a jam.
  • Not using the belt space wisely, leading to a full belt and no moves left.
