colonyflow Level 27

Overview

Level 27 is a Normal four-color stage whose target picture is a pixel-art green camper van: a large cream-colored roof and body (about 59% of tiles), gray wheels and undercarriage (about 25%), a red headlight (about 9%), and a green lower body (about 7%), with tiny pink, blue, orange, cyan and black trace accents. The goal is to clear every tile by tapping the number tiles at the bottom so ants carry each color away. Because the tiles are stacked, the green lower body must leave first, then the gray undercarriage, with the cream roof and red headlight finishing as the inner layers.

• Difficulty: Regular (Normal)
• Estimated moves: 25–40 taps

Step-by-Step Solution

1. Start by tapping the green tile. Green forms the lower body of the van and sits on the outermost layer, so it is reachable immediately. Tap it and let the ants march to the body and begin carrying the green squares away.
2. Next, tap the gray tile. Gray is the wheels and undercarriage of the van and sits on the same upper layer. Clear it in one push so the underside opens up.
3. While the gray carry is running, clear the tiny pink, blue, orange, cyan and black trace tiles opportunistically. They become reachable as the undercarriage comes off; tapping them whenever a slot opens keeps the ants busy without blocking a slot.
4. When green and gray are mostly gone, tap the yellow tile. Yellow is the cream roof and body of the van — the largest single area on the board — and was covered by the lower layers, so it only becomes reachable now. Keep the queue pointed at yellow in one continuous push and use the 2x speed-up button in the top-right corner to shorten the wait.
5. Finish with the red tile. Red is the headlight on the front of the van — the bottom layer — so it is the last color to be exposed. Because it is final, the queue can safely be filled with red to speed up the finish.
6. Keep the five-slot queue under active control: push one main color plus at most one small color at a time, finish a color before starting the next, and never jam all five slots with mixed colors.

Strategy & Reasoning

The level is built around the layered-stacking rule: a color that covers others must be carried away first, and the removal order measured in the solution video is green, gray, yellow, red, which matches the geometry of the camper van. Clearing the green lower body before gray matters because it sits on top; tapping gray first would leave that body buried. The queue is the bottleneck — four main colors plus trace accents share only five slots, and the worst mistake is pushing green and yellow at the same time, which leaves no room for the small traces and forces waiting. The efficient play is to alternate the large yellow roof carry with the small gray and trace colors so the ants are almost never idle. The 2x speed-up button should be active for the long yellow body carry, since that single step accounts for most of the level's waiting time. If the queue jams, the Magnet tool pulls one whole color out of the line, while the Eraser is reserved for a single stuck tile.

Tips & Common Mistakes

• Tapping the cream roof before the green lower body and gray undercarriage are gone is the classic mistake. The roof tiles are still covered, so the ants have no path to them; always clear the lower layers first.
• Running green and yellow at the same time jams the five-slot queue and strands the small traces. Finish green and gray completely before starting yellow.
• Ignoring the tiny pink, blue, orange, cyan and black traces leaves slots blocked for no reason. Clear them opportunistically whenever a slot is free, instead of saving them all to the end.
