Marble Sort Level 245 — Walkthrough and Solution

Marble Sort Level 245 presents a vertical challenge: a tall grid with a dense Top Tray of eight columns, a single golden Key perched at the summit, and a heavy Lock blocking the lower middle pathways. Below the Conveyor Belt, four active Boxes (Dark Blue, Purple, Yellow, Cyan) sit atop grey Mystery Boxes, hiding the true color demands until you clear the front line. The initial visible marbles in the Top Tray are misleading: the outer columns display Greens, Pinks, and Reds, but no corresponding Boxes are active at the start, making them lethal bait. The center Lock forces you to tunnel along its sides to reach the upper layers, and the bottom edge features a protruding Red (avoid it), a Purple, and a Dark Blue—the latter two are your lifelines as they match the starting Boxes.

The key to Marble Sort Level 245 is to control the board from the bottom up, feeding the correct colors to the active Boxes without clogging your Conveyor Belt with useless marbles. The Mystery Boxes will reveal new demands—like Orange—so you must be ready to react. The Lock breaks only after you deliver the Key from the top, which then opens the entire center. Manage your belt space meticulously, as a sudden surge of colors becomes available after the Lock shatters.

Marble Sort Level 245 Walkthrough

The bottom row of Boxes, from left to right, demands: Dark Blue, Purple, Yellow, and Cyan initially. Underneath each is a grey Mystery Box that will flip to a new color once cleared, so be prepared for surprises like Orange. The key to success is to ignore the outer columns with Green, Pink, and Red until much later, as pulling them early will jam your belt.

The central trap is the Lock: it blocks the middle routes, so you cannot dig straight up. You must carve through the columns adjacent to the Lock to reach the top. Additionally, a grey blocker tile with a '2' sits above the Lock, requiring you to clear adjacent marbles to tick it down. The visible colors in the Top Tray are arranged to tempt you into mistakes—the Green and Red marbles are pure decoys.

How to Beat Marble Sort Level 245 — Step-by-Step

Phase one: Front-line clearance and Mystery Box reveals

1. Tap the protruding Purple marble from the bottom edge of the Top Tray and drop it into the Purple Box.
2. Next, grab the Dark Blue marble from the bottom edge and route it to the Dark Blue Box.
3. Locate the Yellow marble just above the bottom layer and deliver it to the Yellow Box.
4. Find the Cyan marble slightly higher and feed it to the Cyan Box to clear the first wave.
5. As each Box empties, the Mystery Box beneath activates—immediately check the new color and plan your next moves accordingly.
6. Keep an eye on the far left column: below the Mystery Box sits an Orange Box, so watch for Orange marbles in the Top Tray.

Phase two: Breaking the center Lock

1. Start tunneling up the center-left or center-right column, avoiding the Lock and only pulling marbles that match your active Boxes.
2. When you encounter the grey blocker tile with '2', clear adjacent marbles to reduce its counter and remove it.
3. Continue upward until you reach the top row and can drop the golden Key onto the Conveyor Belt.
4. Deliver the Key to the Lock at the bottom center to shatter it, opening the entire middle section.
5. After the Lock breaks, a large cluster of previously blocked marbles becomes active—resist the urge to pull many at once; instead, focus on matching one color at a time.

Phase three: Final clear and belt management

1. Clear the newly unlocked center, likely containing Orange, Pink, and Blue marbles, by matching them to the remaining lower Boxes.
2. Play one color at a time: if you need Yellow, only pull Yellow until that Box clears and drops away, freeing space.
3. Finally, return to the outer edges and grab the Green and Red marbles that have been waiting all match, dropping them into the last Boxes to finish the level.

Tips & tricks

• Always prioritize matching the bottom-row Boxes before touching any other marble—this keeps your Conveyor Belt clear and your options open.
• When a Mystery Box reveals, immediately adjust your strategy; for example, if Orange appears, scan the Top Tray for Orange marbles before making any other move.
• Use the Conveyor Belt as a temporary holding area, but never let it fill with unmatched colors—leave at least one slot free at all times.

Common mistakes

• Pulling the Green, Pink, or Red marbles from the outer columns early—this chokes your Conveyor Belt and leads to a quick game over.
• Ignoring the Mystery Box reveals and continuing to pull colors that no longer match any active Box, causing your belt to jam.
• Attempting to clear multiple colors at once after the Lock breaks—this scatters your attention and overloads your belt.
