Colony Flow Level 91 Walkthrough Solution & Guides | How to solve Colony Flow 91

Welcome to Colony Flow Level 91 where you face a massive Yin Yang symbol right in the middle of the board. I play every level myself and write these guides to help you clear the board without getting stuck. This level surrounds the central design with four colored corners and four Hungry Doors that demand a huge number of ants to open. You need careful tray management to pull the right blocks and avoid filling your waiting slots.

Colony Flow Level 91 Overview

What You Are Working With

The board features a huge Yin Yang shape made entirely of black and white tiles. Surrounding this central picture are four corners filled with bright colors. The top left corner is red. The top right corner is light blue. The bottom left corner is orange. The bottom right corner starts out light blue but reveals yellow tiles as you dig deeper. Each of these four corners houses a Hungry Door. A Hungry Door requires you to feed it a specific number of ants to open it. All four Hungry Doors start with a requirement of 40 ants. Down in your tray you will find single numbered blocks and Connected Boxes. Connected Boxes are linked together and move as a group when you pull them into your waiting slots. You must plan your pulls so these linked blocks do not jam your five available spaces.

What It Takes to Clear Level 91 Board

Clearing this board means consuming every black and white tile in the central Yin Yang symbol while simultaneously feeding the four Hungry Doors in the corners. You must pull white and black blocks to create paths through the middle. Once the middle opens up your ants can reach the colored tiles in the corners. You then use red orange light blue and yellow blocks to clear the corner tiles and feed the Hungry Doors. The doors count down from 40 to zero. The level ends when the central shape vanishes the colored corners disappear and all four Hungry Doors open. Your main goal is to always keep a path open for the ants so your five waiting slots never fill up completely.

Colony Flow Level 91 Step by Step Solution

Step 1: Pull black and white blocks to start breaking into the central shape

The board begins with the entire Yin Yang symbol blocking the way to the outer corners. You must start by pulling the available black and white blocks from the tray. Look for the black block with a value of 30 and the white block with a value of 25. Pulling these sends your ants straight into the bottom of the black and white design. The ants eat away the outer edge of the Yin Yang shape and open up the first main pathways toward the middle of the board. Keep a close eye on your five waiting slots right from the start. By focusing strictly on black and white blocks early on you guarantee the ants have immediate access to the tiles they need to eat. This ensures your tray stays clear and ready for the next move as you dig deeper into the puzzle.

Step 2: Use connected red blocks to feed the top left Hungry Door

As the ants clear the lower sections of the black and white tiles a path opens to the top left red corner. Your tray now reveals Connected Boxes in red. You will see two red blocks linked together with the number 25. Pull these linked blocks into your tray. The red ants stream out and head straight for the top left corner. They eat the red tiles and begin feeding the top left Hungry Door. The door requires 40 ants and pulling these red blocks reduces that number significantly. Always make sure the ants have an open route before pulling Connected Boxes because they take up multiple spaces in your waiting slots. If the path is blocked those connected blocks will cause you to lose the level instantly.

Step 3: Alternate between black white and red blocks to maintain a steady flow

With the top left red door counting down you need to keep the board moving smoothly. The tray offers more black and white blocks alongside a red block with a value of 6. Pull the black and white blocks to continue carving out the center of the Yin Yang symbol. The white ants and black ants will chew through the middle sections and expose more colored areas. Then pull the red block to send a quick burst of ants to the top left Hungry Door. This brings the top left door requirement down to 18. Maintaining this alternating rhythm prevents your waiting slots from jamming. You clear more of the central obstacle while steadily chipping away at the first Hungry Door. Taking turns between the middle shape and the corner doors is the secret to winning.

Step 4: Introduce orange blocks to attack the bottom left Hungry Door

The continuous clearing of the central black and white tiles eventually exposes the bottom left corner. This corner features orange tiles and its own Hungry Door starting at 40. Your tray will supply an orange block with a value of 6 and later larger orange blocks. Pull the orange blocks to send ants into the bottom left section. At the same time you must continue using white blocks to clear the remaining left side of the Yin Yang shape. The white blocks in your tray such as the 23 and 26 will help finish off the white half of the center. Balancing the orange and white pulls keeps multiple ant streams moving without any dead ends.

Step 5: Pull connected black blocks to clear the dark half of the central shape

Now you must focus your attention on the right side of the board where the black tiles of the Yin Yang symbol remain in large chunks. The tray provides Connected Boxes of black blocks with values like 32 and 36. Pull these linked black blocks into your waiting slots. The black ants will march out and consume a massive chunk of the remaining black tiles in one swift motion. Clearing this huge section is crucial because it completely removes the barrier blocking the right side of the screen. This opens the final pathways to the top right and bottom right colored corners. Because the connected black blocks take up two waiting slots you must ensure the black path is completely clear before making this move. You never want to leave connected blocks stranded in your tray because they severely limit your options.

Step 6: Send light blue ants to the right side Hungry Doors

With the black tiles mostly gone the right side of the board becomes fully accessible. The top right corner contains light blue tiles and a Hungry Door. The bottom right corner also features a Hungry Door that is ready to be fed. Look in your tray for light blue blocks. Pull the light blue blocks with values like 25 and 30. The light blue ants will divide their efforts and head toward the right side corners. They will start eating the light blue tiles and feed the Hungry Doors. The top right door will drop down to single digits and the bottom right door will begin its countdown from 39. Always verify the light blue path is open so these large blocks do not trap you and end your game prematurely.

Step 7: Deploy yellow blocks to conquer the bottom right section

As the bottom right corner clears you will notice yellow tiles underneath the initial layers. The bottom right Hungry Door still needs more ants to open completely. Your tray will now offer yellow blocks to match these newly exposed tiles. Pull the yellow blocks with values like 21 and 17. The yellow ants will swarm the bottom right area and eat the yellow tiles. They will also march straight into the bottom right Hungry Door and drop its requirement down to 12. You must continue pulling small light blue blocks to finish off the top right door at the same time. Keep scanning the board to make sure both yellow and light blue paths remain unobstructed.

Step 8: Clear the final scattered tiles to finish the level

Only a few random tiles and nearly open Hungry Doors remain on the board. The top right door requires just 9 more ants and the bottom right door needs exactly 12. Your tray will provide small single blocks of light blue yellow red and black. Pull a light blue block with a value of 1 to finish the top right section. Pull a red block with a value of 17 to clean up any remaining red tiles. Finally pull the remaining yellow blocks to feed the last few ants into the bottom right Hungry Door. Once the final door hits zero and opens the board clears completely. You win the level by carefully managing these final pulls and keeping your waiting slots empty right until the very end.

Final Thought

This level tests your ability to juggle the center design while slowly chipping away at four separate corners.
