Marble Sort Level 151 Guide: The Front-Row Bait and Key Trap

You are likely stuck on this board because of a massive spacing trap right at the start. Marble Sort Level 151 immediately tempts you with easy grabs that will ruin your run.

Look at the dominant colors. You have bright clusters of Orange, White, Light Blue, Purple, and Red sitting right at the front of the Top Tray. Behind them sits a jagged wall of standard marbles. Two huge wooden crates dominate the middle of the board, splitting your access into three narrow lanes.

The bottom Boxes are stacked in four deep columns. The immediate targets available are Red, Light Blue, and two Purples. The real danger here is the Lock and Key obstacle. The White Box in the fourth column is sealed shut with a padlock. A second lock hides at the very bottom of the center stack. You cannot blindly clear colors. You must hunt specific keys to open up your sorting lanes before the belt overflows.

The Locked Column Pattern in Marble Sort Level 151

Every move on this board requires you to look three steps ahead. The bottom area dictates your opening moves entirely.

Here is exactly how your four lower columns are stacked. The extreme left column goes Red, Orange, Orange, White, Green. The second column runs Light Blue, Brown, Red, Purple, White. The third column holds Purple, White, Brown, Pink. The fourth column starts with Purple, but directly underneath it is that dreaded locked White Box, followed by two Greens.

This specific bottom layout makes the front row of the Top Tray incredibly dangerous. The Orange and White clusters sitting at the bottom of the upper tray look ready to play. They are pure bait. Tapping them first will immediately clog your Conveyor Belt because there are no active Orange or White Boxes ready to receive them.

The two giant wooden crates in the upper section force you to play the outside edges. Your keys are scattered in terrible spots. You have a Purple key pinned on the far left edge. A Yellow key sits identically on the far right. The center lane holds an Orange key, a Blue key, and a Pink key near the top. You have to carefully chew through the left and right flanks to expose these Key marbles, all while managing a severely restricted Conveyor Belt.

Marble Sort Level 151 Step-by-Step Walkthrough

Follow this exact order to safely dismantle the front row and unlock the fourth column without jamming your belt.

Bypassing the Front Bait in Marble Sort Level 151

Your first taps must perfectly match the exposed lower Boxes. Do not touch anything you cannot immediately clear.

1. Tap the Red cluster marble on the far right of the Top Tray. This drops immediately into the active Red Box in column one.
2. Tap the Light Blue cluster marble in the center. This clears the active Light Blue Box in column two.
3. Tap the Purple cluster marble. This routes perfectly into the open Purple Boxes in columns three and four.
4. Stop tapping. Do not touch the Orange or White clusters yet. Leave them sitting exactly where they are.

Unlocking the White Box in Marble Sort Level 151

Now that the initial front layers are gone, the board starts to shift. Clearing those first three Boxes exposes an Orange Box on the left and a Brown Box in column two.

1. Drop the Orange cluster from the front row now. The left column is ready to take it.
2. With the front row finally gone, tap the single Purple marble on the left edge that carries the first key.
3. Send the single Green marble sitting below the Purple key to the belt.
4. Pull the Orange marble with the key from the left-center lane.
5. Clearing these Key marbles will crack the lock on the White Box in the fourth column.
6. Drop the White cluster from the Top Tray into your newly unlocked White Box.

Cracking the Top Crates in Marble Sort Level 151

The middle of the board is going to get tight. You must work around the wooden crates by stripping the outer columns completely bare.

1. Shift your focus to the far right edge. Pull the Yellow marble with the key, then the Brown marble beneath it.
2. Feed the Brown marble into the active Brown Box in column two.
3. Start pulling the exposed White and Green marbles from the center lane. The left side of the bottom area is now hungry for White and Green.
4. Dig straight up the middle gap between the two wooden crates. You need to access the Blue Key marble.
5. Once the Blue key is collected, the final lock at the bottom of the board will break open.
6. Keep your Conveyor Belt clear for the final Pink and Green keys at the absolute top of the tray. Route the remaining singles into the surviving bottom Boxes to finish the stage.
