Marble Sort Level 151 is a puzzle that demands careful sequencing from the start. The board features a Top Tray with several marbles that seem easy to remove, but many of them are decoys. The key is to focus on the lower containers first and ignore the tempting front row until the right containers are open.

The layout includes two large wooden crates in the upper area, splitting the play space into three lanes. The bottom has four columns of containers. On the far left, the stack from top to bottom is: Red, Orange, Orange, White, Green. The second column holds Light Blue, Brown, Red, Purple, White. The third column contains Purple, White, Brown, Pink. The fourth column starts with Purple, but underneath it is a locked White container, followed by two Greens.

Marble Sort Level 151 Walkthrough

Your first moves must match the currently open containers at the bottom. The front row of the Top Tray has clusters of Orange, White, Light Blue, Purple, and Red, but only Red, Light Blue, and Purple have open containers initially. The Orange and White clusters are traps because their corresponding containers are not yet available.

The critical imbalance is that the White container in the fourth column is locked, and you must find keys to unlock it. The keys are scattered on the left and right edges and in the center lane. If you tap the Orange or White clusters too early, you will fill your Conveyor Belt with marbles that cannot be placed, causing a jam.

How to Beat Marble Sort Level 151 — Step-by-Step

Phase one: Clear the safe colors

  1. Tap the Red cluster marble on the far right of the Top Tray. This drops into the open Red container in the first column.
  2. Tap the Light Blue cluster marble in the center. This goes into the open Light Blue container in the second column.
  3. Tap the Purple cluster marble. This fits into the open Purple containers in the third and fourth columns.
  4. Now stop. Do not touch the Orange or White clusters yet. Leave them as they are.

Phase two: Unlock the White container

  1. After clearing those three, the board shifts. An Orange container opens on the left, and a Brown container appears in the second column.
  2. Now drop the Orange cluster from the front row into the left column.
  3. Next, tap the single Purple marble on the far left edge that holds a key.
  4. Send the single Green marble sitting below that Purple key to the belt.
  5. Pull the Orange marble with a key from the left-center lane.
  6. Collecting these keys will unlock the White container in the fourth column.
  7. Now drop the White cluster from the Top Tray into that newly opened White container.

Phase three: Crack the crates and finish

  1. Turn your attention to the far right edge. Pull the Yellow marble that has a key, then the Brown marble beneath it.
  2. Feed that Brown marble into the open Brown container in the second column.
  3. Start pulling the exposed White and Green marbles from the center lane. The left side of the bottom area now has open containers for these colors.
  4. Work your way up the middle gap between the two wooden crates. You need to reach the Blue key marble.
  5. Once you collect the Blue key, the final lock at the bottom of the board will break open.
  6. Keep your Conveyor Belt clear for the last Pink and Green keys at the top of the tray. Route the remaining single marbles into the surviving bottom containers to complete the level.

Tips & tricks

  • Always check which containers are open before tapping any marble from the Top Tray.
  • Prioritize unlocking the locked containers early to expand your options.
  • Use the Conveyor Belt as a buffer, but don't let it get full—plan your taps to keep it moving.

Common mistakes

  • Tapping Orange or White clusters too early, which floods the belt.
  • Ignoring the keys and trying to clear colors blindly.
  • Forgetting to clear the outer edges before moving to the center, which can trap marbles behind the crates.
