Colony Flow Level 237 Walkthrough Solution & Guides | How to solve Colony Flow 237

Colony Flow Level 237 brings you a large pixel art picture of a Highland cow. You have to feed your ant colony by clearing out the thick red body and heavy brown shading along with the surrounding light blue background. The level includes three colored keys placed around the picture that you must collect to unlock specific blocks stuck in your tray. You need to manage your tray space carefully to avoid filling all five waiting slots while you wait for paths to open. Playing this level requires a steady pace and a good eye for which colors are ready to be eaten.

Colony Flow Level 237 Overview

What You Are Working With

The main picture shows a Highland cow standing in a field. The background consists entirely of light blue tiles that frame the animal. The cow itself features a large red body with dark brown shading on the legs and underbelly. The hooves are built from dark gray and beige tiles. The horns have white and pink details. You will notice three key tiles positioned on the board right from the start. A blue key sits on the bottom left corner of the background. A yellow key sits on the bottom right corner of the background. A green key sits way up on the top right corner. Your tray contains several locks that correspond exactly to these key colors. You also have hidden boxes in the tray marked with question marks. These hidden boxes will reveal their true colors only when they have a valid open path to move to the slots. The tray holds blocks with fairly high numbers like 30 and 40 so the ant streams will take a bit of time to empty out completely.

What It Takes to Clear Level 237 Board

Clearing the board means you must guide your ant colony to eat every single tile of the cow and the entire background. You begin at the bottom edge where the hooves and the lower background tiles meet the open paths. You must prioritize collecting the blue and yellow keys early to unlock the blocked columns in your tray. If you pull too many large red or brown blocks before the hooves are fully clear you will jam your waiting slots and lose the level. The key to winning is keeping your light blue ants moving up the sides while your dark colored ants chew through the center. You win the game when the entire pixel art picture vanishes and the last remaining ants return to the nest hole.

Colony Flow Level 237 Step by Step Solution

Step 1: Open the bottom edge and collect the first two keys

You need to open paths on the left and right sides of the board to grab the keys right away. Pull a light blue 32 block to send a large stream of ants to the bottom left and bottom right corners of the background. This single move targets both the blue key and the yellow key at the same time. You also need to start working on the hooves to open the vertical paths. Pull a dark gray 30 block and a white 10 block to send ants straight up the middle. Keep an eye on your waiting slots as these initial streams get to work. You want the light blue ants to clear the bottom corners completely so the keys get collected. Collecting the yellow key automatically unlocks the yellow lock in your tray. This frees up a blocked column and brings down a red 30 block and a brown 40 block for your next moves.

Step 2: Push into the lower legs and continue up the sides

With the bottom hooves gone you can now access the lower sections of the legs. Pull a brown 40 block from the tray to clear the heavy shading on the legs. At the same time pull another light blue 34 block to keep the background ants moving up the left and right borders. The blue key you collected during the first step will now unlock the blue lock in your tray. This gives you access to even more light blue blocks and reveals a pink 36 block underneath. Make absolutely sure you do not pull a big red block until the brown leg tiles are cleared enough to expose the red belly tiles. If you pull a red block too early it will sit in your waiting slots and block other colors from moving.

Step 3: Attack the main red body and the brown underbelly

You will see a massive section of red tiles forming the main bulk of the cow body. Once the legs are clear you have a direct path to this area. Pull a red 41 block to send a huge swarm of red ants into the center of the board. Pull a brown 35 block to clear the remaining brown shading tucked under the belly area. Your light blue ants should still be working their way steadily up the left side of the background. Always leave at least one waiting slot completely empty just in case an ant stream takes longer than expected to finish its eating path. The hidden boxes in your tray will start revealing their colors as the blocks positioned above them are successfully used.

Step 4: Keep pouring red ants into the central body section

The red body takes up a vast majority of the tiles on this board. You will need to pull multiple red blocks in a row to get through it all. Pull a red 30 block and then a red 26 block from your tray to keep the pressure on the center. You will see the red ants spreading out widely across the broad body area and moving up towards the neck. Keep pulling light blue blocks like a 30 or a 25 as they become available to clear the background along the sides. The right side path needs your attention right now because you want your light blue ants to reach the top right corner where the final key is resting.

Step 5: Reach the top right corner to collect the green key

Your light blue ants on the right side will eventually reach the top right corner of the picture. This specific corner holds the green key. Pull a light blue 30 block to make sure the ants have enough numbers to finish eating that entire corner section. Collecting the green key instantly unlocks the green lock sitting in your tray. This action removes the final barrier because the green lock blocks all access to the specialized face colors you need for the head and horns. Do not pull any random face color blocks until the green lock is fully gone and the columns shift down.

Step 6: Clear the intricate details of the head and horns

Now that the green lock is out of the way you can focus entirely on the cow head. Pull a white 14 block and a pink 16 block to send ants directly to the horns and the snout area. Pull an orange 10 block for the tuft of hair detail resting on the top of the head. Pull a dark gray 7 block to clear out the eyes and the ear tips. The red blocks you pulled earlier should be just finishing up the rest of the upper body and the neck. Make sure your tray slots do not fill up with leftover background colors while you are actively working on these small face details.

Step 7: Clean up the remaining face tiles and hair tufts

The head has a few stubborn layers of color that require smaller block numbers. Pull an orange 1 block to pick off the very last orange hair tile near the horn base. Pull a beige 13 block to clear the specific shading around the nose and mouth area. Pull a final dark gray block to finish the last ear detail on the left side. Your waiting slots will get a little crowded here because the paths are very short and the ants finish quickly. Keep pulling the exact matching colors sequentially so you never have more than three blocks sitting in the slots at any given time.

Step 8: Finish off the top background border

The only tiles left on the board at this point will be the remaining light blue background tiles framing the top edge. Pull a light blue 13 block and a light blue 15 block to send ants to the top left and top middle sections. The light blue ants will swarm the last few tiles from both sides and meet in the middle. Watch as the numbers drop to zero and the final blocks disappear from your tray. The level ends immediately when the final light blue tile is eaten and the ants retreat safely into the nest.

Final Thought

Colony Flow Level 237 tests your ability to balance massive center clearing with careful border management. You have to constantly feed the red and brown center while ensuring your light blue ants never stop climbing the sides to grab those keys. If you struggle with the exact timing of the key unlocks or get stuck on the head details please watch the video above this article. Seeing the ant streams in motion makes it much easier to understand when to pull the large numbered blocks.
