About the dish

Xi'an roujiamo, often called the Chinese burger: a crisp flatbread split and stuffed with slow-braised chopped pork and green peppers.

How the picture comes apart

From the frame to the center the picture is 12 layers deep. The outer ring is mostly gold and navy, the middle band is mostly gold and cream, and the core is mostly dark red and salmon. Ants can only reach the next layer once the one around it is gone, so the core colors are the last to become useful.

By block count the biggest colors are gold, navy and black.

The 1 golden key(s) are buried in the middle band of the picture, so the locks they open come into play around the middle of the level.

1 noodle(s) run through the picture, 48 cells in all. They can only be slurped from their ends, so they act as walls until an end is free and as tunnels after that.

Reading the tray

The tray starts with 40 boxes in 4 columns. At the start 4 of the 4 front boxes can bite right away: teal (bites now), navy (bites now), black (bites now) and navy (bites now).

Locked boxes start in column 2, row 7.

3 mystery box(es) only show their color when they reach the front.

How the verified run plays out

The solution further down was played to the end in the real game, with ants walking and real timing. It takes 40 taps. The chart shows how many boxes were still parked in the 5 slots, waiting for their color, just before each tap.

Opening (taps 1–11): 35% of the blocks are eaten, with up to 0 of the 5 slots holding a box that is waiting.

Middle (taps 12–23): 33% of the blocks are eaten, with up to 2 of the 5 slots holding a box that is waiting.

Ending (taps 24–40): 32% of the blocks are eaten, with up to 3 of the 5 slots holding a box that is waiting.

A key comes out before tap 12.

How hard is it?

Two test players attempted this level many times: a cautious one that only sends colors it can use right away cleared it 88% of the time, and a look-ahead one that tries each option before committing cleared it 100% of the time. Most of their failed attempts jammed in the ending.

Strategy

Check the colors of the first three boxes in each column and compare them with the colors exposed on the outer ring of the picture. Always keep one slot free to catch a color that can't be eaten yet.

This level tightens toward the end and the last third jams most easily. Don't fill all five slots early; keep room for the inner colors that appear layer by layer at the finish.

Keys are buried in the picture and must be dug out to open the locks in the tray. Prioritize colors that eat around the keys so locked boxes don't block the front row for long.

Mystery boxes show their color only when they reach the front. When you see one coming, don't fill every slot; leave room for it.

Noodles are eaten only from an end with a white dot, never from the middle. Look for ends that are already free or about to be: slurping one opens a tunnel straight into the picture and can uncover inner colours early. A noodle with both ends buried is a wall until you dig to one of its ends.

Step-by-step solution

This order of taps is verified to clear the level. Columns are numbered 1–4 from the left; after each tap, wait until the ants are out before the next one. Two boxes shown together are a chained pair taken in one tap.
