Colony Flow Level 366 presents a fun puzzle featuring a cute pixel art dog surrounded by grass and sky. When you first load into this level you will notice several keys scattered across the picture and multiple locked blocks sitting in your tray. Managing these locks is the main challenge you will face here. You have to plan your moves carefully to collect the keys in the right order without ever jamming your five waiting slots. I played through this level and figured out the best way to route the ants and clear the board safely. This guide will walk you through every move you need to make to clear the picture and claim your victory.
Colony Flow Level 366 Overview
What You Are Working With
The picture at the top of your screen shows a large dog sitting in a grassy field with a blue sky background and a tree on the right side. The dog is made of white tiles for the body beige tiles for the shading orange tiles for the spots and tail a black outline and a red tongue. The environment consists of green grass green tree leaves light blue sky and a brown tree trunk.
The most critical elements in this level are the keys resting on specific tiles and the locked blocks in your tray. You will see a green key on the tree a light blue key in the sky and orange keys on the dog tail and ear. Down in your tray you have light blue green white and black blocks readily available. However you will also see solid locked blocks that prevent you from pulling the colors trapped underneath them. You cannot bypass these locks. You must collect the corresponding keys from the board to remove the locks and access the rest of your blocks.
What It Takes to Clear Level 366 Board
Winning this level requires you to clear every single colored tile from the board. You do this by pulling numbered blocks from the tray into your five waiting slots. The ants will leave their nest hole and carry the numbers to the matching colored tiles. Every time an ant eats a tile the number on the block drops by one. When the block hits zero it disappears from your slot making room for a new block.
The primary danger in Level 366 is filling all five waiting slots with blocks that have nowhere to go. If you pull a color that is blocked by other tiles the ants cannot reach it. The block will sit in your slot and wait. If all five slots fill up with waiting blocks the ants stop moving and you fail the level immediately. You must always ensure that the colors you pull have a clear open path to be eaten. By collecting the keys sequentially and carefully managing your slot space you will dismantle the picture piece by piece until the board is completely empty.
Colony Flow Level 366 Step by Step Solution
Step 1: Open the outer edges with green and light blue blocks to create working space.
The very first thing you need to do is create working space for your ants. The dog picture is completely solid right now meaning you cannot reach the inner colors like white or black. You must start from the outside and work your way in. Look at your tray and pull the heavy green block and the light blue block. The green ants will immediately pour out of the nest hole and turn towards the bottom grass and the lower left side of the picture. The light blue ants will take a slightly different route heading up the left edge to attack the sky tiles. You want these ants to carve a path along the entire left side of the board. This opens up the boundary of the dog and exposes the white and orange tiles you will need to target next. Keep a close eye on the block numbers as they tick down. Do not pull any other colors yet because they simply do not have a way to reach the picture.
Step 2: Send white and beige ants to clear the main body of the dog.
As the green and light blue ants chew away the left side of the grass and sky the white edge of the dog chest becomes completely exposed. Now is the time to start clearing the main body of the dog. Pull a white block from the tray and watch the white ants stream through the newly opened paths on the left. They will start eating the chest and front legs of the dog. Shortly after the white ants get to work you will expose the beige tiles that make up the shading on the dog face and underbelly. Pull a beige block into your waiting slots to send ants after these tiles. Your slots are going to start filling up with different colors right now. You will have green light blue white and beige all sitting in the slots at the same time. You must let these ants work steadily without crowding the board. Wait for at least one of these blocks to finish and vanish before you pull another block from the tray.
Step 3: Collect the light blue keys from the sky tiles to unlock the tray.
While the white and beige ants are busy hollowing out the dog body your light blue ants will continue advancing up the left side of the sky. You will spot light blue keys sitting on top of some of these sky tiles near the top left corner. Collecting these keys is mandatory because you have a blue lock blocking a huge section of your tray. Feed another light blue block into your available slots to keep the pressure on the top left corner. The ants will march all the way up the left wall and finally eat the tiles holding the keys. As soon as the keys are collected the blue lock down in your tray shatters and vanishes. This reveals fresh blocks that you need to keep the ants moving. The left side of the board is now mostly empty giving your ants a massive highway to travel around the remaining picture.
Step 4: Attack the black outline and the orange tail to grab the next key.
With the left side clear and new blocks unlocked you can start picking apart the details of the dog. The black outline is now fully exposed on multiple sides. Pull a black block to send ants after this border. The black ants will trace the shape of the dog clearing the outline tiles from the bottom and the left. At the same time pull an orange block to target the dog tail. The tail is sticking out on the left side making it an easy target for your orange ants. The tail holds another key that you will need very soon. The orange ants will swarm the tail and eat the tiles granting you the key. Be very careful with your waiting slots during this phase. You have ants traveling farther across the board now which means the blocks stay in your slots longer. Never pull a block unless you are absolutely sure the ants have an immediate unblocked path to their color.
Step 5: Collect the green key from the right side tree to unlock more blocks.
Your focus must now shift to the right side of the board. There is a large green tree taking up the entire right edge and a green key is resting near the top of its leaves. The grass on the bottom right is already gone which means your green ants have a clear shot at the tree. Pull a heavy green block from your tray. The ants will bypass the remaining dog tiles entirely and march straight to the right side. They will start eating the tree from the bottom up. As they climb higher they will eventually reach the green key and collect it. Grabbing this green key unlocks yet another section of your tray. The board is looking much thinner now. The entire left half is empty and the tree on the right is shrinking rapidly. This open space is exactly what you want because it prevents the ants from getting stuck in narrow tunnels.
Step 6: Unlock the yellow block by clearing the orange ear at the top.
You still have a stubborn yellow lock sitting in your tray blocking access to your final blocks. The key to this lock is resting on the orange ear at the very top of the dog head. The white and beige ants have already cleared most of the face so the orange ear is completely exposed. Pull another orange block into your slots. The ants will travel straight up the middle of the empty board and swarm the ear. When they eat the tile holding the key the yellow lock in your tray will finally break. This action completely opens your tray. You have access to every single block you need to finish the puzzle. Make sure the orange ants finish their block before you pull anything else just to keep your slots tidy and safe from jamming.
Step 7: Clear the remaining tree trunk and the last bits of face shading.
The picture is now reduced to a few scattered chunks. You have the brown tree trunk on the right side some beige shading left on the right side of the dog face and the red tongue. Pull the brown block from your newly unlocked tray section. The brown ants have a very long walk across the entire board to reach the tree trunk. Because they take so long to arrive the brown block will sit in your waiting slot for a while. This is why you kept your slots clear earlier. While the brown ants are walking pull a beige block to clean up the rest of the dog face. You can also pull the red block to clear the tongue. Let all these ants do their work and watch the numbers count down. Do not worry if your slots look full right now. As long as the ants are actively eating the numbers will eventually reach zero and free up the space.
Step 8: Finish the final scattered tiles to complete the picture and win.
You are now in the final stretch of the level. The solid picture is completely gone leaving only a few random scattered tiles across the top and right edges. You will see a few lingering light blue sky tiles a couple of green leaf tiles and maybe a single black outline tile. Look at the very bottom of your tray. You will find small numbered blocks perfectly sized for these remaining tiles. Pull the matching colors one by one. The ants will rush to the top corners and the right edge to clean up the very last pieces of the board. The numbers on your blocks will hit zero precisely as the last tiles vanish. Once the final ant finishes eating the board is totally clear and you win the level.
Final Thought
Level 366 tests your ability to plan ahead and manage your tray space while dealing with locked blocks. Collecting the keys in the correct order is the only way to keep your block supply flowing smoothly. If you ever feel like the ants are taking too long to reach their targets just remember to pause and let the waiting slots clear out before pulling more colors. If you find any of these steps tricky to follow in text please watch the video above this article. Seeing the ants move in real time will help you understand exactly how the paths open up and how to time your block pulls perfectly.
