Marble Sort Level 788 — Walkthrough and Solution

Marble Sort Level 788 is a trap-laden puzzle where a single wrong tap on a numbered release box can flood your conveyor and end the run. The winning move is to first clear all free marbles, then selectively open the numbered boxes, leaving the '4' box for last.

The top tray holds four numbered boxes: a '2' on the left (with Yellow and Silver), a '4' on the right (with Light Blue and Silver), and two '3' boxes in the center (one with Purple, one with Pinkish-red). Below these are loose marbles in Orange, Green, Cyan, etc., plus a bottom row of textured marbles in Purple, Black, Brown, and Green. The bottom has four deep columns; the visible top-layer Boxes are: Column 1 Pink, Column 2 Purple, Column 3 Orange, Column 4 Purple.

The front-row Boxes demand, from left to right: Pink, Purple, Orange, Purple. Underneath, you'll find Brown, Green, and more. The critical imbalance: the '4' box releases four Light Blue marbles, but there is no Light Blue Box anywhere on the board—so tapping it early jams your conveyor with unusable marbles.

Only by delaying that tap until all other marbles are cleared can you let those Light Blue and Silver drops fall into an empty system and vanish.

How to Beat Marble Sort Level 788 — Step-by-Step

Phase one: Clear the loose marbles

1. Tap the free-floating Orange marble and route it to the Orange Box in Column 3.
2. Guide the single Pinkish-red marble from the center-right to the Pink Box in Column 1.
3. Use the loose Purple marble to fill the Purple Box in Column 2, which reveals another Purple Box underneath.
4. Release the textured Brown marble from the bottom row to the newly exposed Brown Box in Column 1.
5. Continue by sending the single Green and Cyan marbles to their matching Boxes, systematically emptying all non-numbered marbles from the tray.
6. Keep your conveyor light by releasing only one or two marbles at a time; do not touch any numbered box yet.

Phase two: Open the '3' and '2' boxes

1. Once all free marbles are gone, you'll only have the numbered boxes left. Tap the '3' box that holds Purple marbles; three will drop—feed them into the waiting Purple Box.
2. Then tap the other '3' box with Pinkish-red marbles; release them and fill the corresponding Pink Box.
3. Now tap the '2' box on the top left; it will drop two Yellow and two Silver marbles. Send the Yellows to their Box, and let the Silvers circle on the conveyor for now—there is space.

Phase three: The final '4' box

1. Verify that every colored Box is cleared, leaving only the '4' box on the top right and possibly a few Silver marbles circling.
2. Tap the '4' box last. It releases four Light Blue and four Silver marbles—all have no matching Box.
3. Because your conveyor and Boxes are empty, these junk marbles drop, circle once, and disappear, completing the level. If you tap this box earlier, you lose.

Tips & tricks

• Always clear free marbles before opening any numbered box to keep the belt unclogged.
• Use the '3' boxes only when you have a matching Box ready to receive them.
• Let the Silver marbles from the '2' box ride the belt; they won't cause problems if you have room.
• Save the '4' box for the absolute end—it's pure poison otherwise.

Common mistakes

• Tapping the '4' box early, which floods the belt with Light Blue and Silver, causing an instant jam.
• Opening numbered boxes before clearing loose marbles, leading to a full conveyor and no place to put the drops.
• Forgetting to check if a matching Box exists before releasing a numbered group.
