About the dish

A little stone bridge crossed the creek, and its round arch met its reflection to make a perfect circle. We leaned over the railing watching the fish for half a day at a time.

How the picture comes apart

From the frame to the center the picture is 18 layers deep. The outer ring is mostly light blue and teal, the middle band is mostly grey and light blue, and the core is mostly light blue and grey. 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 light blue, teal and grey.

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 54 bites from soldier ants.

Reading the tray

The tray starts with 97 boxes in 4 columns. At the start 3 of the 4 front boxes can bite right away: green (has to wait), grey (bites now), grey (bites now) and teal (bites now).

Chained pairs start in column 1–2, row 17, column 1–2, row 20, column 1–2, row 24, column 2–3, row 16, column 3–4, row 18, column 3–4, row 19 and column 3–4, row 22.

Locked boxes start in column 2, row 12.

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

4 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 90 taps. The chart shows how many boxes were still parked in the 5 slots, waiting for their color, just before each tap.

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

Middle (taps 35–65): 35% of the blocks are eaten, with up to 4 of the 5 slots holding a box that is waiting.

Ending (taps 66–90): 31% of the blocks are eaten, with up to 0 of the 5 slots holding a box that is waiting.

A key comes out before tap 27. The web breaks before tap 47. Chained pairs are taken at taps 59, 65, 70, 72, 73, 78 and 86.

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.

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.

Chained boxes need both halves in the front row and two free slots. Take the boxes in front of them first and free two neighboring slots in advance.

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.
