Marble Sort Level 398 presents a deceptive cross-shaped layout where early restraint is the key to victory. The board immediately demands four colors in the bottom boxes—White, Light Pink, Yellow, and Orange—while the top tray dangles a mix of colors that can easily lure you into mistakes. The primary strategy is to clear the bottom boxes in a precise order, ignoring the tempting but dangerous clusters that would clog your Conveyor Belt.
The board features two panels near the top that require clearing three bottom boxes to unlock, plus two lock-and-key mechanisms that guard additional marbles. Brown clusters hold the keys, and once dropped, they release Light Green and Light Pink clusters. Four grey Surprise Bags on the outer wings add unpredictable colors, making late-game belt space precious. A successful run depends on executing the opening moves flawlessly.
Marble Sort Level 398 Walkthrough
The bottom boxes, from left to right, demand White, Light Pink, Yellow, and Orange. The top tray's bottom row holds clusters of Yellow, Light Blue, Dark Green, and Light Pink. The trap lies in the Light Blue and Dark Green clusters—they are decoys with no matching bottom boxes initially.
The panels are marked with '3', meaning you must clear three bottom boxes to shatter them. The locks are anchored by Brown clusters; the left lock secures a Light Green cluster, and the right lock secures a Light Pink cluster. The Surprise Bags sit on the jagged wings, ready to introduce random colors.
How to Beat Marble Sort Level 398 — Step-by-Step
Phase one: The Opening Panel Crack
- Tap the Yellow cluster on the bottom-left of the top tray, sending it to the Yellow bottom box in the middle-right, clearing it.
- Route the Light Pink cluster on the bottom-right to the Light Pink bottom box in the middle-left, clearing it.
- Expose and drop the Orange cluster on the left into the Orange bottom box on the far right.
- Slide the White cluster on the right into the White bottom box on the far left.
- Watch the panels shatter after four clears, revealing the upper tray.
Phase two: Unlocking the Inner Board
- Drop the Dark Green cluster now that a Green bottom box is available on the far left.
- Hunt the Brown clusters in the newly revealed upper section, routing marbles to expose them.
- Once the Brown clusters are dropped into matching bottom boxes, the golden keys turn, releasing the Light Green and Light Pink clusters from their locks.
- Open the Surprise Bags one at a time, immediately matching any revealed colors to available bottom boxes.
Phase three: Clearing the Final Reds
- Feed Red clusters from the upper-mid section to the Red bottom boxes that have cycled up.
- Process the remaining hidden colors from the Surprise Bags one by one, keeping your Conveyor Belt clear.
- Match front-to-back as the board empties, ensuring no dead weight accumulates.
Tips & tricks
- Never tap the Light Blue cluster early—it has no matching box and will jam your belt.
