Level 373 Board Overview: The Crate-Plugged Tray

Level 373 opens with a tray that looks blocked on purpose. The flanking target stations at the top left and top right each hold a small stack of colored pieces — Pink and Purple on the left, Pink, Red, and White on the right — and each station is fronted by a grey numbered “2” marker that pays double when you feed it. Between the stations, the center of the board is a vertical grid of stacked columns, and most of them are sealed.
The crates are the headline. Solid brown wooden crates sit low in the outer columns, locking away whatever rides underneath them, while a single X-marked crate caps the very top of the center column. The visible colors around the blockade are honest: Orange tiles sit in the middle columns (one with a grid pattern), a Purple rides high on the left, and a Dark Blue patterned tile hides near the bottom of a right-side column.
Down below, the conveyor is already loaded: two Pink-toned marbles lead, followed by two Greens and then a long run of Orange — six or more in a row. Under the belt, rows of waiting block stacks in Red, Green, Blue, Yellow, Orange, and White sit ready to receive. The trap is that the belt’s biggest batch, Orange, has no open target anywhere on the opening board.
The Trap in Marble Sort Level 373
The tray is rigged to make you grab the biggest batch first. Here is the layout:
- Wooden crates seal the useful columns: solid crates plug the lower half of the outer columns and the X-crate caps the center column. Everything under a crate is unreachable until the crate clears, so the opening targets are only the pieces stacked above the wood.
- Only the flank colors have targets at the start: Pink, Purple, Red, and White feed the two top stations. Orange, Dark Blue, Yellow, and Green have no open Box on the opening board — feed them early and you jam the belt.
- The numbered “2” markers double your drops: each flank marker counts as two pieces toward whichever station it feeds. They are the best taps on the board, but only if the color behind them matches an open slot.
- The belt pre-loads a long Orange run: six-plus Oranges are already queued when the level starts. The batch is bait until the Boxes rotate toward Orange — let it ride the belt instead of forcing it.
Marble Sort Level 373 Step-by-Step Walkthrough
Work the flank stations before you touch the middle. Follow the release order.
Opening: feed the flank stations

- Tap the Pink piece stacked at the left station into the left target — it is the safest drop on the board.
- Feed the Purple beside it into the same station; the left station clears quickly and cycles toward new colors.
- Move to the right station and drop the top Pink, then the Red beneath it.
- Clear the White to finish the right station’s opening stack.
- When the grey numbered “2” marker reaches a matching slot, tap it — it counts double, so time it for a color whose station is wide open.
- Leave the conveyor alone for now: the Pink-Green-Orange run at the front of the belt only matches targets that have not cycled in yet.
Midgame: crack the crates open
Once the flank stations cycle, the Boxes start asking for the middle colors and the crates become fair game. The center column’s X-crate and the solid crates in the outer columns drop as their supporting pieces clear, releasing the Orange, Dark Blue, and patterned tiles buried underneath.
- The moment an Orange Box opens, start feeding the belt’s waiting Orange run — a full batch finishes a Box in a single pass and empties the queue.
- Drop the two Greens from the belt’s opening run into the Green slot as soon as it appears.
- Work the center column down past the X-crate; the Orange tiles it was capping are now live targets.
- Treat the patterned Red, Orange, and Dark Blue tiles as their base colors — feed each one when its Box cycles to the front.
- Keep the columns under the solid crates for last; they release a mix of Dark Blue and Yellow that needs the later Boxes.
Cleanup: chase the stragglers
With the tray nearly empty, the level becomes a straight finishing line. The end frame shows the grid stripped down to a handful of single pieces — Pink, Purple, Green, Light Blue, Red, and Yellow scattered across the remaining columns with a grey numbered “1” marker left in each flank column, the belt still carrying Red, Blue, and White singles.
- Play only to the active front row from here — every remaining piece is a single waiting for its Box to slide forward.
- Let the belt cycle: feed the Red, Blue, and White singles as their slots open and do not chase colors whose receivers have already closed.
- Tap the final numbered “1” markers when their stations open; they clear the last tall stacks in one pass.
- Finish the final Boxes as the stragglers drop and let the tray empty. The level completes the moment the last marble lands.

Level 373 Tips Recap
- Open with the flank stations: Pink, Purple, Red, and White are the only colors with targets before the crates crack.
- Do not touch the Orange batch on the belt until an Orange Box cycles in — it is the level’s biggest bait.
- Numbered markers pay double, so save them for a color whose station is fully open.
- In the endgame the tray is nearly empty; cycle the belt and feed the last singles into their Boxes.
