About the dish

The old green train at dusk, a yellow stripe and lit windows, rolling along the tracks past the hills; inside, everyone squeezes up to make room for one more.

How the picture comes apart

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

The spider web covers 30 cells in the middle band of the picture and needs 45 bites from soldier ants.

1 number block(s) take 36 bites in total.

2% of the blocks are frozen and take two bites each.

Reading the tray

The tray starts with 94 boxes in 4 columns. At the start 3 of the 4 front boxes can bite right away: navy (bites now), green (has to wait), black (bites now) and black (bites now).

Locked boxes start in column 3, row 15.

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

5 soldier box(es) carry the bites for the web.

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

Opening (taps 1–30): 34% of the blocks are eaten, with up to 4 of the 5 slots holding a box that is waiting.

Middle (taps 31–65): 34% of the blocks are eaten, with up to 3 of the 5 slots holding a box that is waiting.

Ending (taps 66–94): 32% of the blocks are eaten, with up to 4 of the 5 slots holding a box that is waiting.

A key comes out before tap 52. The web breaks before tap 92.

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.

Tight from start to finish. Only take boxes that can send ants immediately, watch the second and third rows of the tray, and plan the next tap ahead.

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.

Ice blocks take two bites, so one block uses two ants. Icy areas are eaten slowly and the matching boxes stay in their slots a little longer.

Nothing under the spider web can be eaten. Wait until the edge of the web is exposed before sending the soldier box (the leafy green one), or it just occupies a slot.

Number blocks take many bites; the number is how many remain. They can be bitten as soon as any side is exposed, and several boxes of that color can work on one at once.

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.
