colonyflow Level 2

Overview

Level 2 is a Normal four-color stage whose target picture is a pixel-art heart built from three stacked layers: a bright pink outer shell (the largest area, about 44% of tiles), a cyan middle body (about 42%), and a small yellow diamond in the center (about 9%), with a thin orange outline trace (about 5%). Tiny accent tiles of blue, green, purple, red and gray sit along the edges. The goal is to clear every tile by tapping the number tiles at the bottom, which sends ants out to carry the matching color away. Because the tiles are stacked, the pink shell must come off before the cyan body is reachable, and the yellow center finishes inside the middle layer.

• Difficulty: Regular (Normal)
• Estimated moves: 12–18 taps

Step-by-Step Solution

1. Start by tapping the pink tile. Pink forms the outermost shell of the heart and covers most of the board, so the ants cannot reach anything underneath it until it leaves. Tap pink and let the first batch of ants march to the upper lobes of the heart and begin carrying the pink squares away.
2. While the pink carry is running, tap the yellow tile. Yellow is the small center diamond, and clearing it early keeps a tiny color from lingering once the shell is gone. Watch the center open up as the yellow squares drop out.
3. Continue tapping pink until the entire outer shell is carried off. Do not move on fully to cyan until most of the pink is gone; any leftover pink keeps covering the middle layer and blocks the ants' path.
4. Next, tap the cyan tile. With the pink shell gone, the cyan body of the heart is now exposed and reachable. Keep the queue pointed at cyan in one continuous push so the ants strip the middle layer cleanly. Use the 2x speed-up button in the top-right corner to shorten the long carry.
5. Sweep the orange outline last. Orange is the thin bottom trace running along the edges, and it only becomes reachable once cyan is finished. Clear it in small bulk at the end; because it is the final color, filling spare queue slots with orange is safe.
6. As you pass them, tap the tiny trace colors (blue, green, purple, red, gray) whenever a queue slot opens up. They are too small to start a dedicated push, but leaving them scattered keeps a slot blocked for longer than necessary.
7. 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 a textbook layered-stacking puzzle: pink physically covers cyan, which covers the yellow center, so the removal order measured in the solution video is pink first, then yellow, then cyan, with orange finishing last. Tapping cyan or yellow at the very start would waste ants on tiles that are still buried under the pink shell. The queue is the main constraint — four main colors share only five slots, and letting pink and cyan run simultaneously leaves no room for the small trace colors, which then stall. The efficient pattern is to alternate a large color (pink, then cyan) with the small colors (yellow, orange, traces) so the ants are almost never idle and a slot is always free. The 2x speed-up button should be active for the long pink and cyan carries, since those two steps account for most of the level's waiting time. If the queue ever 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 pink shell is gone is the classic mistake. The cyan tiles are still covered, so the ants have no path to them; always clear pink first.
• Running pink and cyan at the same time jams the five-slot queue and strands the small colors. Finish pink completely before starting the cyan push.
• Ignoring the tiny trace colors (orange outline, blue/green/purple/red accents) leaves slots blocked for no reason. Clear them opportunistically whenever a slot is free, instead of saving them all to the end.
