colonyflow Level 51

Overview

Level 51 is a Normal four-color stage whose target picture is a pixel-art sun with a green base: a green body (about 49% of tiles), a yellow face (about 37%), orange rays (about 8%), and cyan outlines (about 6%), with tiny blue, red, gray, brown, black and pink 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 base must leave first, then the yellow face, with the orange rays and cyan outline finishing as the bottom layers.

• Difficulty: Regular (Normal)
• Estimated moves: 20–35 taps

Step-by-Step Solution

1. Start by tapping the green tile. Green is the sun's base and sits on the outermost layer, so it is reachable immediately. This is the largest single area on the board, so this is the long opening stretch. Keep the queue pointed at green in batches and use the 2x speed-up button in the top-right corner to shorten the wait.
2. Next, tap the yellow tile. Yellow is the sun's face and sits on the same upper layer. Clear it in one push so the face opens up.
3. While the yellow carry is running, clear the tiny blue, red, gray, brown, black and pink trace tiles opportunistically. They become reachable as the base comes off; tapping them whenever a slot opens keeps the ants busy without blocking a slot.
4. When green and yellow are mostly gone, tap the orange tile. Orange is the sun's rays and was covered by the face, so it only becomes reachable now. Keep the queue pointed at orange in one continuous push and keep an eye on the queue.
5. Finish with the cyan tile. Cyan is the outline around the sun — the bottom layer — so it is the last color to be exposed. Because it is final, the queue can safely be filled with cyan to speed up the finish.
6. Keep the five-slot queue under active control: with four main colors plus trace accents 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 green, yellow, orange, cyan, which matches the geometry of the sun. Clearing the green base before the yellow face matters because it sits on top; tapping yellow first would leave that base 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 green base carry with the small yellow, orange and trace colors so the ants are almost never idle. The 2x speed-up button should be active for the long green base 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 orange rays before the green base and yellow face are gone is the classic mistake. The ray tiles are still covered, so the ants have no path to them; always clear the base and face first.
• Running green and yellow at the same time jams the five-slot queue and strands the small traces. Finish green completely before starting yellow.
• Ignoring the tiny blue, red, gray, brown, black and pink traces leaves slots blocked for no reason. Clear them opportunistically whenever a slot is free, instead of saving them all to the end.
