This board is a chain-lock puzzle with a hidden trap in the front row. To beat it, you must first clear the Green and Dark Blue boxes on the right, then feed the Light Blue box that appears, and only later return to the White and Yellow marbles you initially left alone. The key is disciplined order: right side first, then middle, then left.
On the upper tray, the front row holds White and Yellow marbles on the left, with Green and Dark Blue on the right. Behind them, deeper in the tray, are Light Blue, Red, and other colors. The bottom boxes are arranged in columns: the first column requires Pink, Red, Green, and Dark Blue in that vertical order; the second column has Red, then Yellow; the third has Green; the fourth has Dark Blue. Two wooden Crates sit on the left and right edges, and a chain with a padlock blocks the upper-middle area. Multiplier Gates marked x2 sit on the far left and right, and Mystery Boxes are at the bottom.
Marble Sort Level 340 Walkthrough
The front row of the top tray is a decoy. The leftmost White and Yellow marbles are visible and easy to tap, but they are not needed yet. The boxes that need them are buried under the Pink box in the first column. Tapping them early will send them to the Conveyor Belt, where they will sit and block space while you dig for Pink and Red. The actual targets are on the right: the third box wants Green, and the fourth wants Dark Blue. These are the ones you must feed first.
The imbalance is that the front row on the left is a trap, while the right side holds the key to progress. The Conveyor Belt has limited space, and the x2 Multiplier Gates can double any marble that passes through, which becomes a disaster if the belt is already full. So you must avoid any early drops that are not necessary.
How to Beat Marble Sort Level 340 — Step-by-Step
Phase one: Clear the right side
- Tap the Green marbles in the middle-left of the front row to send them into the third bottom box.
- Tap the Dark Blue marbles on the right side of the front row to fill the fourth bottom box.
- After the Green box is cleared, a Light Blue box appears underneath it. Tap the Light Blue marbles from the front row to feed that box.
- Keep clearing these colors; each clear counts toward smashing the adjacent wooden Crates. After three clears, the Crates will break and release new marbles.
Phase two: Break the chain
- Once the right side is open, tap the Red marbles in the center column to fill the second box that needs Red.
- As you clear more colors, the Crates on the left and right will break, dropping extra marbles, including the Pink ones you need for the first column.
- Now dig up to the top left and top right corners to collect the gold Keys. Tap the blocks holding them.
- When both Keys are collected, the padlock shatters and the chain disappears, opening the entire upper half.
Phase three: Survive the late game
- Clear the next layer of bottom boxes to reveal the Mystery Boxes' true colors.
- When using the x2 Multiplier Gates, only drop a marble if you have an open box of that color ready to receive it. Otherwise, the doubled marble will clog the belt.
- Finally, go back to the left side. The White and Yellow marbles you ignored are now safe to drop, as their boxes are exposed. Clear them to finish the level.
Tips & tricks
- Always check the bottom box order before making any move; a single wrong tap can fill the belt.
- Use the x2 Multiplier Gates only when you have a matching empty box, to maximize efficiency without risk.
- Watch the Conveyor Belt capacity; if it fills, the level ends, so prioritize clearing boxes that are close to full.
Common mistakes
- Tapping White or Yellow at the start, which clogs the belt and blocks your path to Pink.
- Dropping marbles through the x2 Gate without a ready box, causing overflow.
- Ignoring the Mystery Boxes until they are forced to reveal, leaving you unprepared for the final colors.
