About the dish

The lunch box from the dining-car trolley: lift the lid for rice, braised pork, greens and a fried egg, with a pair of disposable chopsticks.

How the picture comes apart

From the frame to the center the picture is 18 layers deep. The outer ring is mostly black, the middle band is mostly grey and yellow, and the core is mostly white and yellow. 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 grey, black and white.

Reading the tray

The tray starts with 81 boxes in 4 columns. At the start 1 of the 4 front boxes can bite right away: green (has to wait), yellow (has to wait), black (bites now) and white (has to wait).

18 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 81 taps. The chart shows how many boxes were still parked in the 5 slots, waiting for their color, just before each tap.

Opening (taps 1–29): 34% of the blocks are eaten, with up to 4 of the 5 slots holding a box that is waiting.

Middle (taps 30–51): 33% of the blocks are eaten, with up to 4 of the 5 slots holding a box that is waiting.

Ending (taps 52–81): 33% of the blocks are eaten, with up to 1 of the 5 slots holding a box that is waiting.

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.

The start is easy and the pressure builds in the middle. Use the calm opening to sort out the back rows and try to have two slots free before the middle phase.

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.

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.
