Marble Sort Level 651 — Walkthrough and Solution

Marble Sort Level 651 presents a board that seems locked down from the start. The struggle centers on a pair of vertical chains that trap the second and sixth columns, while the bottom of the middle columns is blocked by large textured blocks (two Green and one Red). The bottom row of Boxes requires Pink, Cyan, Red, and another Cyan. Success depends on releasing the chains in the correct order without letting the conveyor belt clog.

The layout is a criss-cross lock-and-key puzzle. The left chain is held by a Purple Lock, the right by an Orange Lock. The Orange Key sits at the top of the left column, while the Purple Key rests at the top of the right column. To reach them, you must dig through the unblocked middle and far-left columns. The bottom Boxes dictate a strict opening: the front row has a 4-slot Pink Box, a 3-slot Cyan Box, a 3-slot Red Box, and another 3-slot Cyan Box. Behind them are Green Boxes and many Mystery Boxes. The far-left column in the Top Tray has a Yellow marble at the bottom, followed by Green marbles—this is a decoy because there is no Yellow Box in the visible front or second rows, so tapping it early would waste conveyor space.

Marble Sort Level 651 Walkthrough

Your immediate goal is to clear the front Cyan and Pink Boxes. That will shift the lower board and reveal the Mystery Boxes' demands. Only then should you break the textured blocks in the center.

The key insight is to avoid the far-left Yellow marble entirely until a Yellow Box appears. Instead, focus on the middle and right columns to gather Cyan and Pink marbles, then clear the Red Box using Red marbles from the top.

How to Beat Marble Sort Level 651 — Step-by-Step

Phase one: Clear the front row

1. Tap the accessible Cyan marbles from the center and right columns to fill the first Cyan Box.
2. Route Pink marbles from the same area into the Pink Box.
3. After the Cyan Box fills, clear it by tapping the checkmark.
4. Continue feeding Pink marbles to the Pink Box until it is complete.
5. Now pull Red marbles from the top area (avoiding the Yellow bait) to fill the Red Box.
6. Clear the Red Box once full.
7. Use the second Cyan Box as a temporary holder for extra Cyan marbles while you work.

Phase two: Break the center blocks and reach the Keys

1. With the front row gone, the bottom board shifts, revealing Mystery Boxes. Observe their color demands.
2. Start breaking the large textured Green and Red blocks in the center of the Top Tray. Use Green marbles for the Green blocks and Red for the Red block.
3. As you break blocks, match any accessible marbles to the revealed Mystery Boxes immediately to free conveyor space.
4. Dig upward through the middle columns, prioritizing the side that gets you to a Key faster (Orange on left, Purple on right).
5. When you reach a Key marble, drop it into any matching colored Box (if available) or hold it temporarily if needed.

Phase three: Release the chains and finish

1. Once you clear the first Key, the corresponding chain shatters, freeing a flood of marbles.
2. Use these newly available marbles to quickly fill all remaining Mystery Boxes.
3. If a Yellow Box has appeared, finally tap that far-left Yellow marble and clear it.
4. Navigate to the second Key, clear it, and break the final chain.
5. Sort any remaining marbles by color, clearing the board to win.

Tips & tricks

• Always check the Mystery Boxes' colors before pulling from the top tray; don't grab a marble unless its Box is active.
• Use the conveyor belt as a short-term buffer, but never let it hold more than one or two marbles.
• When breaking textured blocks, work from the edges to avoid trapping yourself.

Common mistakes

• Tapping the far-left Yellow marble early, which jams the belt.
• Ignoring the Mystery Boxes and focusing on the chains too early.
• Clearing the second chain before the first, which can cause a blockage.
