colonyflow Level 91

Overview

Level 91 is a Normal six-color stage built around a yin-yang taiji symbol picture — the classic black-and-white circle with its comma-shaped halves. Yellow is the largest area of the picture as the background and frame, followed by pink, red and orange in the middle layers, with gray and brown as the smaller outline colors and tiny trace colors scattered on top. The tiles are stacked in layers, so the clearing follows the symbol from the outside in: pink leaves first, then yellow, then red and gray, then brown, and orange finishes at the bottom. With six colors competing for only five queue slots, disciplined queue switching is the whole challenge.

• Difficulty: Regular (Normal)
• Estimated moves: 25–35 taps

Step-by-Step Solution

1. Open with pink. Pink is the outermost accent layer of the yin-yang frame, so nothing underneath it can be carried away until it is gone. Tap the pink tile and let the ants start the outer clear.
2. Move to yellow next. Yellow is the background and the largest area of the picture, so this is the long stretch of the level. Tap yellow, use the 2x speed-up button to shorten the repeated waiting, and keep the queue from filling with any second color while the ants run.
3. Work the red phase. Red tiles were covered by the outer colors, so they only become reachable now. Clear red in one continuous push and keep an eye on the queue.
4. Work gray next. Gray tiles were covered by the brighter colors, so they only become reachable in the middle of the level. Clear gray in one push.
5. Clear the trace colors (cyan, blue, black) as they are exposed. These small accents hide inside the symbol, and the efficient play is to spend free queue slots on them immediately so they never block a slot during the main pushes.
6. Finish with brown and orange. These are the bottom layers of the picture, so they only become reachable at the very end. Sweep them in bulk; since they are the final colors, it is safe to fill the queue and let the ants finish the board. The yin-yang disappears completely and the level-complete overlay with five white input slots appears.

Strategy & Reasoning

The removal order is dictated by the layer geometry: pink and yellow cover the frame, red and gray sit on the middle layers, and orange is the bottom layer, so the sequence pink → yellow → red → gray → brown → orange keeps the ants on reachable tiles. Yellow is the strategic bottleneck — it is the largest single area, and the correct play is to give it a long uninterrupted run while using spare queue slots for the small trace colors. With six colors and only five queue slots, the worst mistake is pushing two large colors at once, which leaves no room for small colors and forces waiting. The efficient play is to alternate a main color with small trace colors so the ants are almost never idle, and to save Magnet and Lightning only for rescuing a jammed queue.

Tips & Common Mistakes

• Running yellow and red at the same time jams the five slots and stalls the board. Finish one main color before starting the next.
• Ignoring the small trace colors until the queue is full leaves an unmatchable tile blocking the line. Clear every exposed accent immediately with a free slot.
• Opening a "?" tile while the queue is full can block the line. Open unknown tiles only when a queue slot is free.
