Marble Sort Level 312 is a tricky puzzle that demands patience and precise planning. The key is to avoid the Light Blue and Dark Blue marbles at the start, as they will clog your Conveyor Belt and cause a jam. Instead, focus on clearing the bottom slots in the right order to unlock the board's full potential.
The board features a central Tunnel marked with a '3' that releases marbles in phases. Flanking the Tunnel are two columns of Iced Boxes that need to be broken open. In the Top Tray, the bottom row (left to right) holds Yellow, Light Blue, Red, Dark Blue, and Pink marbles. Above that, the outer left column has Orange, Light Blue, and Brown; the inner left has an Iced Box with Orange, Purple, and Yellow; the inner right has Iced Boxes with Red and Green; the outer right has Purple, Light Blue, and Green. The bottom Boxes have three layers of demands: the front row needs Red, Brown, Pink, and Yellow; the second layer needs Brown, Pink, Green, and Pink; the third layer needs Light Blue, Green, Light Blue, and Yellow.
Marble Sort Level 312 Walkthrough
The bottom Boxes initially show a row of four colored slots (left to right): Red, Brown, Pink, and Yellow. Your first goal is to clear these without touching the deceptive Light Blue and Dark Blue marbles in the top row.
The main trap is that the top row's Light Blue and Dark Blue marbles are tempting but not needed until much later. If you drop them early, they will occupy valuable belt space and block the marbles you actually need.
How to Beat Marble Sort Level 312 — Step-by-Step
Phase One: Clearing the Front Row
- Tap the Yellow marble in the top row's bottom-left position, sending it to the Conveyor Belt, which clears the Yellow slot in the front row.
- Next, tap the Red marble (third from left in the top row) to clear the Red slot.
- Then tap the Pink marble (far right in the top row) to clear the Pink slot.
- Now, locate the Brown marbles in the outer left column of the Top Tray. Tap them to clear the remaining Brown slot in the front row.
- Do not touch the Light Blue (second from left) or Dark Blue (fourth from left) marbles in the top row. Leave them for later.
Phase Two: Managing the Central Tunnel
- After the front row clears, the second layer of bottom Boxes slides forward, now demanding Brown, Pink, Green, and Pink.
- The central Tunnel will begin to release Blue and Light Blue marbles. Only tap them when you have a matching bottom slot ready.
- Tap the Pink and Green marbles that are exposed in the Top Tray to feed the current slot demands.
- As you clear slots, the Iced Boxes will start to thaw. When the inner right column's ice breaks, immediately tap the Green marbles inside to fill a Green slot.
- On the left, when the Iced Box with Orange and Yellow breaks, hold off. Do not drop Orange or Yellow until a matching slot appears, or you will jam the belt.
Phase Three: Final Cleanup
- Once the second layer is cleared, the third layer appears, requiring Light Blue, Green, Light Blue, and Yellow.
- Now you can finally tap the Light Blue marble from the very top row that you saved earlier. Use it to clear the first Light Blue slot.
- The central Tunnel will dispense its final marbles. Route them quickly to matching slots to avoid belt congestion.
- Sweep the outer columns: drop any stray Purple and Orange marbles only when their corresponding slots appear.
- Finally, clear the remaining Light Blue and Green marbles on the right side to complete the level.
Tips & tricks
- Always keep an eye on the Conveyor Belt capacity. If it fills up, you lose.
- Plan your moves ahead: know which colors you need next and where they are located.
- Break Iced Boxes strategically only when the corresponding slot is active, to avoid clutter.
Common mistakes
- Tapping the Light Blue or Dark Blue marbles too early, causing a jam.
- Dropping Orange or Purple before their slots are ready.
- Ignoring the central Tunnel's output and letting it flood the belt.
