Marble Sort Level 712 is a puzzle where a tall barrier of grey blocks sits in the center of the upper area. The key is to first clear the Red and Orange marbles you can see, then gently dig into the grey to find White for the two boxes on the right. Do not rush; the board is designed to punish hasty taps.
The top area is split into four vertical lanes. At the very top, each lane holds a key: Blue on the far left, then Purple, Orange, and Green on the far right. Under each key sit two glass marbles of the same color. Below those glass marbles is a wide grey wall made of 14 blocks, each marked with a question mark. Under that wall, you can see flat panels colored Pink, White, and Yellow. At the very bottom of the upper area, there is a 3 by 3 grid of marbles: Red on the left, Light Green in the middle, and Orange on the right.
Marble Sort Level 712 Walkthrough
Your starting containers on the lower row, from left to right, ask for Red, Orange, White, and White. The visible Red and Orange marbles are easy to feed, but the two White boxes have no White in sight. Those White marbles are hidden inside the grey wall.
The main trap is that the right side of your conveyor belt is useless until you find White, but digging into the grey wall too quickly can flood your belt with unwanted colors. Also, there are locked boxes at the bottom that will end the game if they slide forward before you release their matching keys from the top.
How to Beat Marble Sort Level 712 — Step-by-Step
Phase one: Clear the visible colors
- Tap the Red marbles that are on the lower left of the upper grid and send them to the leftmost Red box.
- Next, tap the Orange marbles on the lower right and route them to the Orange box that is next to the Red box.
- Now you have some open space on your belt. Carefully tap one grey block at a time from the bottom of the wall. If you reveal a White marble, feed it to one of the White boxes. If you reveal a different color, let it sit on the belt for now.
- Keep tapping grey blocks one by one, always looking for White. When you find a second White, send it to the other White box.
- Once both White boxes are filled, the lower row will shift, and new boxes will appear.
Phase two: Break the wall and manage the flood
- After clearing the White boxes, the grey wall will start to break apart. You will see a jumble of Yellow, Light Blue, Purple, and a Mystery Box on the left side. Also, the path to the top keys is now open.
- As the wall breaks, your belt may fill with Light Blue and Pink marbles. Prioritize any boxes that ask for Light Blue or Pink and clear them immediately to free up space.
- Now look at the lower row: you will see locks that need Purple and Blue keys. Focus on the top right area.
- Break the glass marbles under the Orange key and the Green key. Drop the Orange key once an Orange lock appears, and do the same for the Green key.
- On the left side, there is a Mystery Box. Do not tap the marbles blocking it until you have at least three empty slots on your belt, because you need room for whatever random color it demands.
Phase three: Unlock the final locks
- Clear the Purple glass marbles in the second column from the left. Then drop the Purple key down to unlock the Purple lock that is in the middle-left of the lower rows.
- Clear the Blue glass marbles in the far-left column. Drop the Blue key to unlock the last lock at the bottom.
- After all four keys are used, the remaining boxes are just Yellow and Light Green. Clear them by matching the colors carefully, and do not let your belt fill up completely.
- Finish the level by clearing the last few boxes, keeping your taps slow and steady.
Tips & tricks
- Always tap the grey wall one block at a time, and never tap the same spot twice in a row unless you need to clear a specific color.
- Keep an eye on the Conveyor Belt's open slots; if it fills to the end, you will lose.
- When you see a Mystery Box, make sure you have space on the belt before you uncover it.
Common mistakes
- Digging into the grey wall too quickly can flood your belt with unwanted colors, leaving no room for White.
- Forgetting to unlock the bottom locks before they slide forward will end the game.
- Letting the Conveyor Belt fill past the last slot because you tapped too many grey blocks in a row.
