Colony Flow Level 837 Walkthrough Solution & Guides | How to solve Colony Flow 837

Welcome to Colony Flow Level 837. This puzzle presents you with a very cute pixel art creature that looks like a dark blue dragon sitting against a bright light blue background. You have to feed your ant colony by breaking down this detailed picture piece by piece. The game demands precise timing because making the wrong move will trap your ants and end your run immediately. I play every single level of this game and I verify every solution myself. I am going to walk you through exactly how to beat this board and clear the picture without ever getting stuck.

Colony Flow Level 837 Overview

What You Are Working With

The pixel art shows a dragon character with large ears and bright green eyes. The main body consists of dark purple and regular purple tiles mixed together to form the head and legs. The eyes are bright green with small black centers. The wings and the large square background behind the dragon are made of light blue tiles. Down in your tray you have blocks matching all of these exact colors. The blocks start with specific numbers printed on them. These numbers tell you exactly how many tiles that group of ants will eat before the block disappears. You also have a special mechanic on this level called Connected Boxes. You will spot these later in the tray when two blocks have a thick line joining them together. You have to pull Connected Boxes as a single pair and they will clear their matching tiles at the exact same time.

What It Takes to Clear Level 837 Board

Winning this game comes down to strict space management in your waiting slots. You have exactly five empty slots located directly below the board. Every time you tap a block from the tray it moves up into one of these slots. The ants then run out of the nest hole to eat the matching tiles on the board. If a block has no matching tiles open to eat it just sits perfectly still in the slot. If you fill all five slots with blocks that cannot reach their food you lose the level right then and there. To clear this board you must work entirely from the bottom up. You need to chip away at the base of the dragon to expose the wings and the belly. You only pull colors that have an open path to their food. This guarantees your slots never jam up and your ants keep moving freely.

Colony Flow Level 837 Step by Step Solution

Step 1: Pull the light green block into your waiting slots to reach the dark purple block underneath.

You need to reach the dark purple blocks at the bottom of the tray to start eating the base of the dragon. The top row of your tray currently blocks your access. Pull the light green block holding the number seventeen. The dragon eyes are green but they are surrounded completely by dark purple tiles right now. The light green ants cannot reach the eyes yet so this block will sit idle in your first waiting slot. This is a highly calculated risk to uncover the dark purple block underneath.

Step 2: Send the dark purple ants to eat the bottom border of the dragon.

Now you have a clear path to select the dark purple block holding the number thirty. Pull it into the slots. These ants immediately stream out of the nest hole and run straight to the bottom edge of the dragon. They start eating the feet and the very bottom row of the dark purple body. As they eat the tiles the number thirty begins to drop rapidly. The ants open up the lower section of the board which exposes the bottom tips of the light blue wings on both sides. Keeping the bottom edge constantly clearing is the best way to open multiple paths early in the game.

Step 3: Move the white block to free up space in your tray.

The tray still has a white block holding the number two sitting in the front row. There are no white tiles exposed on the board at this moment. You must pull this white block down to your waiting slots to uncover the light blue blocks trapped directly behind it. Your slots now hold the waiting light green block and the waiting white block. You still have three empty slots available which gives you plenty of room to maneuver. Always keep a close watch on your empty slot count so you do not accidentally trap yourself.

Step 4: Release the light blue ants to consume the outer wings.

With the white block out of the way you have full access to a light blue block holding the number fifteen. Pull it into the slots right away. The light blue ants rush up the board and split off to the left and the right. They target the newly exposed bottom sections of the light blue wings. The wings wrap around the lower half of the dragon body. Clearing these outer edges ensures you do not get stuck trying to dig straight through the center too early. The light blue block completely empties and vanishes from your slots.

Step 5: Clear the main body using large purple blocks.

The tray now presents a large purple block with the number thirty eight. Pull this block to send a massive wave of ants into the center of the board. They start chewing through the main body and the chest of the dragon. This is a highly satisfying moment as the entire bottom half of the pixel art completely disappears. The dark purple and regular purple tiles mix throughout the body section. You will pull several dark purple and purple blocks in sequence here to keep the ants flowing. Just watch the numbers count down and verify that the body tiles are actually disappearing before you pull the next color.

Step 6: Activate the waiting light green block to clear the eyes.

As the purple ants finish eating the neck and the lower face of the dragon the bright green eyes finally become exposed to the open board. The light green block that has been sitting in your very first waiting slot since the beginning of the level suddenly springs to life. The light green ants sprint out of the nest and devour the eye tiles. This entirely removes the block from your waiting slot and frees up valuable space for the final stretch of the puzzle. Managing this delayed activation perfectly is what prevents a total board jam.

Step 7: Deploy the connected purple boxes to finish the face.

Deep in your tray you will now encounter the Connected Boxes special element. You will see a purple block with a three connected by a thick solid line to a purple block with an eleven. Because they are joined you must pull them together. Select the connected pair and watch them drop into your slots. The ants swarm the remaining purple tiles on the upper head and the large ears of the dragon. The connected boxes empty out rapidly as the entire face vanishes from the board. Only the top light blue background remains standing.

Step 8: Flood the top background using the connected light blue boxes.

The final challenge is a massive wall of light blue tiles sitting at the very top of the board. Your tray now shows two connected light blue boxes both holding the number thirty five. Pull this connected pair down immediately. An enormous colony of light blue ants floods the board. They spread across the entire top section and eat away the background block by block. You will follow up with one final light blue block holding the number thirty two to clean up the very top corners. The board clears completely and you win the level.

Final Thought

Colony Flow Level 837 requires real patience at the start to ensure you do not trap your blocks in the slots. By strategically holding the light green block and focusing purely on the bottom border you keep your paths wide open. If you find yourself struggling with the timing of the connected boxes or the exact order of the early pulls I highly recommend you watch the video above this article. Seeing the ants move in real time makes the whole strategy crystal clear.
