colonyflow Level 15

Overview

Level 15 is a Normal seven-color stage whose target picture is a pixel-art raccoon: a yellow background panel behind it (about 44% of tiles), gray shading (about 16%), a cyan body (about 13%), red mask and tail rings (about 12%), blue outline (about 6%), orange feet (about 5%), brown base (about 4%), with tiny pink and black trace accents and a white belly. 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 gray shading and yellow background must leave first, then the red, blue and cyan layers, with the orange feet and brown base finishing as the bottom layer.

• Difficulty: Regular (Normal)
• Estimated moves: 40–60 taps

Step-by-Step Solution

1. Start by tapping the gray tile. Gray forms the shading on the raccoon and sits on the outer layer, so it is reachable immediately. Tap it and let the ants march to the shading and begin carrying the gray squares away.
2. Next, tap the yellow tile. Yellow is the background panel behind the raccoon and sits on the same upper layer. Clear it in one push so the panel opens up.
3. While the yellow carry is running, clear the tiny pink and black trace tiles opportunistically. They become reachable as the background comes off; tapping them whenever a slot opens keeps the ants busy without blocking a slot.
4. When gray and yellow are mostly gone, tap the red tile. Red forms the mask and tail rings of the raccoon and was covered by the background, so it only becomes reachable now. Clear red in one continuous push and use the 2x speed-up button in the top-right corner to shorten the wait.
5. Next, tap the blue tile. Blue forms the outline of the raccoon and is exposed only after red finishes. Sweep blue in a moderate push, keeping spare slots free.
6. Then tap the cyan tile. Cyan is the raccoon's body and becomes reachable once the blue outline is gone. Clear cyan in small batches so no slot is wasted.
7. Next, tap the orange tile. Orange forms the feet of the raccoon and is exposed only after cyan finishes.
8. Finish with the brown tile. Brown is the base under the raccoon — the bottom layer — so it is the last color to be exposed. Because it is final, the queue can safely be filled with brown to speed up the finish.
9. Keep the five-slot queue under active control: with seven main colors sharing five slots, 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 gray, yellow, red, blue, cyan, orange, brown, which matches the geometry of the raccoon. Clearing gray and yellow before red matters because the shading and background sit on top; tapping red first would leave those small tiles buried. The queue is the bottleneck — seven main colors share only five slots, and the worst mistake is pushing yellow and cyan at the same time, which leaves no room for the small traces and forces waiting. The efficient play is to alternate the large yellow carry with the small red, blue and trace colors so the ants are almost never idle. The 2x speed-up button should be active for the long yellow background 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 cyan body before the gray shading and yellow background are gone is the classic mistake. The body tiles are still covered, so the ants have no path to them; always clear the upper colors first.
• Running yellow and cyan at the same time jams the five-slot queue and strands the small traces. Finish yellow and red completely before starting cyan.
• Ignoring the tiny pink 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.
