Colony Flow Level 406 Walkthrough Solution & Guides | How to solve Colony Flow 406

Welcome to Colony Flow Level 406. This level features a pixel art picture of a mermaid surrounded by clouds on a green background. You will face a serious challenge with locked boxes that clog your waiting slots until you collect the corresponding keys on the board. I will guide you through every move to ensure you keep your ant paths open and clear the entire board without jamming your slots.

Colony Flow Level 406 Overview

What You Are Working With

The board displays a large mermaid with red hair, a yellow body, and black outlines. She is set against a massive green background with several white and light blue clouds scattered around. Some of the yellow tiles on the mermaid contain floating yellow keys. You need to collect all of these keys to unlock the black blocks in your tray. Your tray contains a mix of single color blocks and hidden connected blocks. Some of these connected blocks contain black locked boxes. When you pull a locked box into your waiting slots, it will just sit there and take up valuable space until you find and collect every single yellow key on the board. This reduces your usable slots from five down to four or even three. Managing your active paths becomes incredibly tight under these conditions.

What It Takes to Clear Level 406 Board

To win this level, you must clear every single colored tile from the picture. Your main obstacle is the lock and key mechanic combined with the massive green background. You will need to carefully balance pulling blocks to clear the accessible colors like green, red, and light blue, while steadily working your way into the yellow tiles to gather the keys. Because the locked black blocks will jam your waiting slots early on, you must never pull a block unless you are absolutely sure its color has an open path on the board. If you fill your limited open slots with colors that are blocked by other tiles, your ants will stop moving. When the ants stop moving, the slots will jam completely, and you will lose the level.

Colony Flow Level 406 Step by Step Solution

Step 1: Open up the outer edges of the background and the clouds to get the ants flowing

You need to get the ants flowing immediately by targeting the exposed colors on the outer edges of the picture. Start by pulling a green block and a light blue block from the top row of your tray. The green block sends ants to chew away at the bottom corners of the massive green background. The light blue block targets the light blue clouds on the right side of the board. Next, pull a red block to start clearing the left side of the mermaid red hair. You also need to pull the first set of hidden connected boxes from the tray. This pull reveals a black locked box connected to a white block. The white block will send ants to clear the white clouds, but the black box will remain stuck in your waiting slots because it is locked. You now have only four functional slots to work with. You must watch your upcoming moves very closely to avoid filling the remaining spaces with colors that have no open paths.

Step 2: Dig deeper into the red hair and continue clearing the green background

With one slot permanently blocked by the locked black box, you must keep your other active blocks moving efficiently. Pull another green block from the tray to keep the ants chewing on the green background. The green background is extremely large, so you will need a constant stream of green ants throughout the entire level. Pull another red block to continue clearing the red hair. The red hair is currently blocking access to the yellow body tiles, so clearing the red tiles is a massive priority. You want your active block numbers dropping steadily. Your light blue block will finish its cloud and leave an empty slot. Fill that empty slot with another green block or a red block to keep the momentum going. Never pull a color that is trapped behind the red or green tiles. Doing so will cause a fatal jam in your waiting slots and end your game.

Step 3: Access the yellow body tiles to start collecting the keys

Once your red ants have cleared enough of the hair on the left side, the yellow tiles of the mermaid body become fully exposed. This is your chance to start working on the keys. Pull a yellow block from the tray to send yellow ants to the body. As they clear the yellow tiles, they will collect the yellow keys floating above them. Every key you collect brings you one step closer to unlocking the black box that is clogging your waiting slots. While the yellow ants are working, do not forget about the rest of the board. Keep pulling green blocks to whittle down the large green background. Managing the green background alongside your main objective is crucial because it requires so many blocks to clear completely.

Step 4: Clear the remaining red hair on the right side to open more paths

The right side of the mermaid hair is still intact, and it blocks further access to the right side of the board. Pull more red blocks from the tray to send ants to clear this remaining red hair. You will see a red block drop to a low number as it finishes off the last bits of hair. Meanwhile, pull a white block to clear the remaining white clouds on the left side of the picture. The yellow ants are still working their way down the body towards the tail, where the final keys are located. Your waiting slots are still tight because the black box is still locked. You must be completely disciplined with your pulls. Only bring up colors that have clear unobstructed paths on the board to prevent any gridlock.

Step 5: Manage a second locked black box while clearing the green background

As you progress through the tray, you will pull another connected set of blocks. This set contains a black block connected to another black locked box. This means you now have two black blocks permanently stuck in your waiting slots until you collect the final keys. This is the most dangerous part of the level because you now only have three usable slots left. You have a green block eating the bottom left of the background, another green block eating the top right, and a white block finishing a cloud in the middle. You must let these active blocks finish their work before pulling anything else. Do not panic and pull random blocks. Wait for the green and white numbers to count down and clear from the slots. Your entire focus must be on keeping those three remaining slots cycling properly without introducing a color that cannot move.

Step 6: Work your way down the tail to expose the final keys

The final keys are located on the yellow and light blue tail section of the mermaid. Pull more green blocks to clear the background around the tail. Removing the green tiles gives your ants better access to the inner sections. You will also pull a light blue block to clear the light blue sections of the tail. This exposes the very last yellow tiles holding the final keys. Your slots are still heavily restricted by the two locked black boxes. You must ensure that the green ants and light blue ants never stop moving. If a green block finishes, immediately replace it with another green block if there is still background left to clear. Keep the pressure on the tail area so you can finally reach those last keys and break the locks holding your black blocks hostage.

Step 7: Collect the last key and unleash the black ants to finish the level

You are now ready to make the final push to clear the board. Pull the last connected block from the tray, which contains a light blue block connected to a yellow block. The yellow block will send ants to eat the very last yellow tiles on the tail. As soon as the yellow ants eat those tiles, you will collect the final key. The moment the last key is collected, the locks on the black boxes in your waiting slots will break. The black ants will immediately swarm out of the nest and race up the board to eat the black outlines, the eye, and the mouth of the mermaid. With the black boxes finally out of your slots, your tray space opens up completely. You can now relax and let the final green and white ants clean up the last few tiles on the board. The picture will clear completely, and you will win the level.

Final Thought

Level 406 demands extreme patience and careful slot management due to the locked black boxes occupying your limited space early on. You have to balance chewing through the massive green background while precisely cutting a path to the yellow keys. If you ever find yourself struggling to understand which blocks to pull first or how to navigate the tight slot restrictions, please watch the video above this article. Seeing the exact sequence of pulls and how the paths open up can make all the difference in clearing the board without a fatal jam.
