Level 8 is a sandwich with a brown crust, green lettuce, pink ham, beige cheese, a white egg, and a yellow yolk. Hidden boxes reveal additional tray options as the board opens. The route is outside in: remove the crust and fillings before asking ants to reach the protected egg and yolk.
The objective is to leave enough queue space for a hidden-box reveal. A newly exposed color is information, not a command to load it immediately. Check its target before using a slot.
Start with the accessible brown crust and any immediately reachable outer edge color. This creates a lower route into the sandwich and exposes the first filling layers.
Use green and pink when their lower or side sections are open. Let each color begin reducing before adding the next one, because the fillings still share a limited passage around the sandwich.
Bring in beige after the fillings have gaps. The cheese clear opens the area surrounding the egg white and keeps the later center colors from being trapped behind an intact layer.
Use white for the egg when enough of the outer ingredients are gone. The egg is large, so it can support a longer-running block once the route is open.
As boxes become visible, pause and identify the revealed color and its target. Use it only if the board has an active path; otherwise let a working block finish first and preserve queue space.
Yellow belongs after white ants have removed the egg layer around the yolk. Finish with remaining brown and white blocks only when their matching tiles are plainly reachable.
The safest hidden-box habit is to keep one flexible slot until the box has revealed its color. This separates seeing new information from committing to it, which prevents a surprise tray block from becoming a stalled queue item.
Loading yellow before the egg white has opened a route is the usual jam. If yolk does not start reducing, reset to the crust-and-fillings sequence. Do not open a hidden box when all other slots are occupied by slow blocks.
The yolk is inside the egg white. Yellow ants need white ants to make a route to the center first.
Check the board before using it. A revealed color can wait in the tray until its matching tiles have an open path.
