Marble Sort Level 423 presents a daunting V-shaped layout that narrows into a central choke point, with a two-marble plug blocking progress. The key is to avoid the tempting Blue box on the far left and instead start with Green, then Brown, to free up space before tackling the plug.
The board is split into two wings. The left wing's top edge holds Pink, Yellow, and Light Blue; below them are Light Blue and Purple; the bottom edge has Green, Brown, Orange, and Yellow. The right wing's top contains Dark Blue, Pink, and Green; the middle layer has Purple, Orange, and Brown; the bottom tip has two Green marbles side by side. In the center, a Dark Blue marble sits atop a Pink one, forming a plug that blocks the middle column.
Marble Sort Level 423 Walkthrough
The active front row, left to right, demands Blue, Brown, Green, and Pink. Behind them, the stacks are: far left goes Blue, Brown, Green; inner left goes Brown, Blue, Pink; inner right goes Green, Brown, Pink; far right goes Pink, Blue, Brown.
The Blue box on the far left is a decoy—it needs three Dark Blue marbles, but only one is in the top right corner and the other is the center plug. Trying to clear it first floods your conveyor with junk, so you must start elsewhere.
How to Beat Marble Sort Level 423 — Step-by-Step
Phase one: Clearing Green and Brown
- Tap the Green marble on the far left edge of the top tray.
- Then tap the two Green marbles at the bottom right tip of the V.
- Now clear the Brown box: send three Brown marbles from the inner slopes near the center.
- Leave the center Dark Blue plug untouched for now.
- Start on the Pink box: grab an exposed Pink from the right wing's middle layer, and another from the upper left if reachable.
Phase two: Breaking the plug and clearing Blue
- Once Green and Brown are cleared, tap the Dark Blue plug to unlock the middle.
- Now the Blue box is safe: get the Dark Blue from the top right corner to finish it.
- Send the Pink that was under the plug down to the conveyor.
- Watch your conveyor space as new boxes (Yellow, Light Blue, Orange) appear—avoid tapping Purple yet.
Phase three: Final cleanup
- Clear Orange and Yellow clusters from both wings.
- Route Light Blue marbles from the top left into the Light Blue box.
- Finally, finish off the large Purple cluster on the right wing.
Tips & tricks
- Prioritize clearing boxes that give you conveyor space, not just any match.
- Always keep the center plug in mind—don't break it until Green and Brown are done.
- Use the conveyor belt as a temporary buffer, but don't let it fill with unusable colors.
Common mistakes
- Tapping the Blue box first, which floods the conveyor.
- Breaking the center plug too early, causing a jam.
- Ignoring the conveyor space, leading to an instant loss.
