Marble Sort Level 787 places you in a three-tier layout that must be solved from the top down. The top tray holds a wooden crate on the left, two rockets with red and white fuses beneath it, and a large panel marked "30" on the right, which seals off all Yellow, Purple, and extra Light Green marbles. The middle section contains two sets of connected boxes: one needs Cyan and Light Green, the other Dark Blue and Cyan, plus a row of single-color boxes requesting Dark Green, Red, Light Green, Pink, and Cyan. The bottom has five columns of boxes packed with Yellow, Purple, and Dark Blue—these are traps until the end.
Your first action is to fire the rockets to destroy the crate, revealing four marbles. Then, focus solely on clearing boxes in the middle to reduce the "30" counter to zero. Ignore the bottom columns entirely until the panel shatters. Once it does, release the flood of Yellow and Purple marbles and systematically clear the bottom columns, starting with one or two to create space. The key is strict sequence: rockets first, middle grind, then bottom cleanup.
Marble Sort Level 787 Walkthrough
The bottom boxes are arranged in five columns. From left to right, the first column demands Yellow and Purple, the second Dark Blue and Cyan, the third Yellow and Light Green, the fourth Purple and Dark Green, and the fifth Light Blue and Pink. These are the ultimate targets, but touching them early will jam your conveyor.
The trap is the apparent abundance of free marbles at the start—Dark Green, Cyan, Orange—that tempt you to rush the bottom. But every marble you send down prematurely fills the conveyor with colors that have no available boxes, causing an instant deadlock. The only safe path is to clear the middle boxes to unlock the panel.
How to Beat Marble Sort Level 787 — Step-by-Step
Phase one: Rocket demolition
- Tap the red-tipped rocket on the left to fire it upward, destroying the wooden crate and revealing four marbles.
- Tap the white-tipped rocket to fire it as well, ensuring the area is clear and all four marbles are accessible.
- Do not release any marbles yet; simply survey the newly exposed colors.
Phase two: Grinding the middle
- Identify which of the revealed marbles match the single-color boxes in the middle row—Dark Green, Red, Light Green, Pink, Cyan.
- Send a marble only if it completes a box immediately; otherwise, leave it in the top tray to avoid conveyor blockage.
- Prioritize the connected boxes: the left set needs 3 Cyan and 2 Light Green, the right set needs 2 Dark Blue and 3 Cyan. Clearing one set deducts 5 from the panel's counter.
- Slowly chip away at the counter, always checking the conveyor space before each release. Patience is essential.
Phase three: Floodgates open
- Once the panel's counter hits zero, the panel shatters, releasing all the Yellow, Purple, and Light Green marbles from the top tray.
- Now shift attention to the bottom columns. Start by sending down all Yellow and Purple marbles to clear the first and third columns, which are dense with these colors.
- Clear one or two columns completely to free up space and simplify the board.
- Continue matching remaining colors column by column until the board is empty.
Tips & tricks
- Always keep a mental map of the conveyor belt's remaining capacity; a full belt with no matching box is a game-over.
- When clearing connected boxes, aim to finish one set entirely before starting another, as partial fills waste space.
- During the final phase, focus on a single column at a time to prevent scattered marbles from clogging your belt.
Common mistakes
- Releasing marbles from the top tray too early, before the panel is open, floods the belt with unusable colors.
- Ignoring the middle boxes and trying to clear bottom columns first—this never works because the needed marbles are locked.
- Firing the rockets in the wrong order or not firing both, leaving the crate partially blocking access.
Marble Sort Level 787 FAQ
Why does my Conveyor Belt flood on Marble Sort Level 787?
Your belt floods because you're sending down marbles that have no matching box to go into yet, especially before the panel is opened or when you ignore the middle boxes.
Which color do I clear first on Marble Sort Level 787?
You should clear the Dark Green marbles first if they are available, as they match one of the single-color boxes in the middle row, helping to reduce the panel counter.
How many moves does it take to clear Marble Sort Level 787?
There is no fixed move count, but you must clear at least 30 marbles from the middle boxes to unlock the panel, and then clear all remaining bottom boxes.
Do I need boosters to beat Marble Sort Level 787?
No, you do not need boosters—the rockets are provided in the level, and careful sequencing is sufficient to win.
What happens if I clear bottom boxes too early on Marble Sort Level 787?
Clearing bottom boxes too early jams your conveyor with colors that have no place to go, because the panel still locks the needed marbles, leading to a deadlock.
