Step-by-step solution
- 1) Release the exposed Dark Blue marbles found on both the left and right of the Top Tray, letting them fall into and empty the top Dark Blue Box of the first column.
- 2) Match the exposed Light Pink Box in the fourth column with the Light Pink marble halfway up the left stack to remove that box.
- 3) Leave the two vertical Tunnels in the center completely alone for now, since triggering them dumps unpredictable colors onto the belt.
- 4) Attend to the Red Box on the lower-left of the upper area, pairing it with the Red receiver in the third column down below.
- 5) Move the White marbles off the upper side stacks into the White receiver resting in column two.
- 6) Shift your attention to the lower right corner and clear the horizontal Tunnel plus the loose marbles above the Yellow Box carrying the key, dropping Light Green and Purple only when their boxes are ready.
- 7) Use the second column sequence of Purple then Light Pink then Light Green to keep the belt empty and shatter the padlock in the third column.
- 8) Immediately fill the unlocked Yellow Box, then nudge the vertical Tunnels a single tap at a time to satisfy each Mystery Box on the outer edges, keeping three belt slots empty to finish.

Frequently Asked Questions
What is the main trap to avoid in Level 518?
The biggest mistake is tapping colors that have no active bottom Box yet. They park on your Conveyor Belt and burn limited slots, so clear the shades that actually have receivers first.
How should I open Level 518?
Ignore the upper layers and aim at the bottom row of the Top Tray. Feed the colors that already have open boxes, then work upward once the lower lanes shift.
When does the midgame color change happen in Level 518?
After the opening boxes fall, the lower columns swap what they demand. Watch for the new shades and only pull blocks that match a box sitting at the front of a lower lane.
Any tip for finishing Level 518 clean?
Keep at least a few empty belt slots before poking mystery or hidden boxes. Feed a revealed color the moment it matches an active box, and fall back to visible marbles when the belt gets tight.
