Colony Flow Level 640 brings a fun surfing bear picture that hides a massive resource management challenge. You face a board dominated by a huge cyan water background and two connected boxes sitting right in the middle of the art. Clearing this level requires careful tray management so you do not fill your five waiting slots with blocks you cannot use. I will walk you through exactly how to break down the background and finish the puzzle step by step.
Colony Flow Level 640 Overview
What You Are Working With
The picture features a brown and orange bear riding a green surfboard across a cyan blue ocean. The background is completely made of cyan tiles. Two wooden connected boxes sit directly on top of the background tiles. These boxes display the number 367 and feature a cyan circle in the center. A teal line connects the two boxes together. The number on these connected boxes represents the exact number of cyan background tiles on the board. As your ants eat the cyan background, the number on the boxes counts down. The boxes act as a solid wall blocking the center of the board until you clear every single cyan tile.
Down in the tray you have a wide variety of numbered blocks waiting for you. You start with large cyan blocks including a cyan 45 and a cyan 40 block. Deeper in the tray you will find brown blocks for the bear, green blocks for the surfboard, and smaller detail colors like magenta, pink, and orange. You will also notice that some blocks in the tray are physically joined together by a colored line. You must pull these joined blocks up into your waiting slots at the same time.
What It Takes to Clear Level 640 Board
You win this level by fully clearing the surfing bear picture and letting the ants exit the board. The central obstacle is the pair of connected boxes. You cannot access the main body of the bear until those boxes break. The boxes only break when you feed the ants enough cyan blocks to clear all 367 background tiles.
You must focus your early game on pulling cyan blocks to satisfy that massive number. You only have five waiting slots at the bottom of the screen. If you pull up too many brown or orange blocks before the bear is actually reachable, those blocks will get stuck in your slots. Filling all five slots with unusable colors causes a dead end. When no ants can move and your slots are full, you lose the level instantly. You must balance pulling the necessary cyan blocks with just enough other colors to keep the edges of the board active.
Colony Flow Level 640 Step by Step Solution
Step 1: Flood the board with cyan blocks to begin reducing the connected box count.
The level starts with the massive cyan background completely exposed and ready for the ants. You need to pull the cyan 45 block and the cyan 40 block from the tray into your waiting slots. The ants will immediately pour out of the nest hole and spread across the cyan pixels. Watch the number on the connected boxes. Every time an ant carries a cyan pixel away, the number drops. Do not pull the purple or brown blocks yet. The ants cannot reach the inner parts of the picture, so those colors will just sit in your slots and waste space. Keep your slots open and dedicated entirely to the cyan water tiles for this opening move.
Step 2: Introduce green blocks to clear the outer edges of the surfboard.
As the ants chew through the bottom layers of the cyan water, the bottom tip of the green surfboard becomes available. You now have a valid path for green blocks. Pull the green 25 block into a waiting slot. The colony will split into two paths. One group of ants will continue eating the cyan water while the other group tackles the green surfboard. Balancing two colors at once keeps the ants moving quickly and prevents traffic jams at the nest hole. The connected boxes will drop into the 180 range during this phase. You still need a massive amount of cyan to break them, so pull the next cyan 17 and cyan 30 blocks into your slots as soon as they become available.
Step 3: Pull small bear colors to keep the flow moving without jamming your slots.
The top and side edges of the picture are now clearing up. The ants have exposed the outer edges of the brown and orange bear. You can now safely pull the orange 9 block and the brown 26 block from the tray. Move these into your waiting slots alongside your cyan blocks. Only pull these bear colors when you are absolutely sure the ants have an open path to reach them. You must never fill your fifth slot with a blocked color. Always leave at least one slot open for a color that the ants are actively eating. This guarantees your board will never dead end. The ants will start nibbling on the ears and arms of the bear while the main group continues destroying the cyan water.
Step 4: Manage the joined tray blocks carefully to open the surfboard stripes.
You will see several blocks in the tray joined by a linking line. One pair includes a magenta block and a pink block. Another pair features a green block joined to a pink block. When you tap one of these joined blocks, both blocks move up into your waiting slots together and take up two spaces. You must wait until the ants have exposed the pink stripes on the surfboard before you pull these joined blocks. Once the pink tiles are touching open space, pull the joined blocks up. The ants will swarm the surfboard stripes and clear them out. The connected boxes are now dropping below 80. Keep pulling any available cyan blocks to keep driving that number down.
Step 5: Break the connected boxes to expose the center of the board.
The cyan background is now almost entirely gone. Pull the final cyan blocks needed to finish the water. The ants will grab the last few cyan tiles scattered around the edges of the picture. The number on the connected boxes drops to 2 and then hits zero. The two connected boxes shatter and vanish from the board. This completely changes the shape of the level. The entire central body of the surfing bear is now totally unprotected. The ants now have direct paths to the large chunks of brown, orange, and yellow pixels that make up the middle of the picture.
Step 6: Flood the main body of the bear with large orange and brown blocks.
Now that the boxes are gone you can rapidly pull the high count blocks from the tray. Pull the large orange 45 block and the brown 45 block into your waiting slots. The ants will rush straight up the middle of the board and consume the body of the bear. You also have access to the yellow pixels making up the nose and the surfboard fins. Pull the yellow 25 block up into an empty slot. Watch your waiting slots carefully during this massive push. Even with the board wide open you must only pull colors that match the remaining pixels.
Step 7: Clean up the final scattered pieces of the puzzle.
The board is mostly empty at this point. Only a few stray brown tiles and a handful of yellow tiles remain on the bear. The tray is also nearly empty. Pull the last brown 9 and brown 8 blocks to finish the fur. Pull the final magenta and cyan blocks to clear out the remaining border details. The ants will easily find the paths to these isolated pixels. The last few tiles vanish into the nest hole and the board clears completely. You win the level without ever triggering a slot jam.
Final Thought
Level 640 demands patience and strict control over your five waiting slots. You must respect the connected boxes and focus on the cyan background before you try to clear the main picture. Keep your block pulls timed with the open paths on the board and you will guide your ants to a clean victory.
