Colony Flow Level 73 Walkthrough Solution & Guides | How to solve Colony Flow 73

Colony Flow Level 73 delivers a fantastic pixel art puzzle shaped like a classic pair of headphones resting around a bright heart. You face a board completely blocked by background tiles and a locked tray that demands careful attention to the board layout. I play every level of this game and verify my methods so you can clear the board without frustration. The key to winning here is pure patience and strict management of your five waiting slots. Let me show you exactly how to feed your colony and clear this board without dead ending your paths.

Colony Flow Level 73 Overview

What You Are Working With

The main picture on your screen features a large colorful set of headphones framing a giant heart. A solid square of light blue background tiles surrounds the entire main image. The headphones have a pink top headband bordered by a thick black outline. The ear pieces have a green outer layer and an orange inner layer. A solid pink heart sits squarely in the middle of the board.

You also have a lock and key puzzle to solve on this board. Look closely at the green outer layer of the ear pieces. A yellow key rests directly on the left green section. A blue key rests on the right green section. Now look down at your tray. You will see blocks of blue, black, pink, green, and eventually orange. Notice the bright yellow padlock attached to a blue block with the number twenty five on it. This locked block traps the pieces beneath it. You cannot use that block until you collect the keys from the board above.

What It Takes to Clear Level 73 Board

Winning this level means peeling the puzzle apart from the outside edges all the way to the center. Your ants start at the nest hole at the bottom of the screen with no clear path to the headphones. You must eat through the bottom blue background tiles first. Clearing that bottom wall opens the path to the green sections. Eating the green sections collects the two keys. The keys automatically unlock the padlocked blue block in your tray. Once the lock breaks you carefully send up black and orange blocks to strip away the rest of the headphones. You win the level when you flood the board with pink blocks to consume the heart and the ants return to their nest.

Colony Flow Level 73 Step by Step Solution

Step 1: Clear the bottom blue boundary to open initial paths

When you start the level your ants have absolutely no path to the main headphone structure because a thick wall of light blue tiles blocks the bottom of the board. You need to pull your first blue blocks from the tray to get the ants moving. Move the blue blocks into your active slots and watch the ants stream out of the nest hole. They will immediately march to the bottom edge of the pixel art and start eating the blue boundary. The numbers on your blue blocks will quickly count down from their starting amounts to zero. Watch your five waiting slots closely during this phase. You never want to fill all five slots with wrong colors like pink because the ants have no way to reach the pink tiles yet. Letting the blue blocks count down safely exposes the bottom of the green sections and the black headband outline.

Step 2: Send green blocks to collect the yellow and blue keys

Now that the bottom layer is open you have a direct path to the yellow key on the left and the blue key on the right. Pull your green blocks with numbers like twelve and ten up into the active slots. The ants will climb up the newly opened paths and begin chomping away at the green outer layer of both ear pieces. Keep a very close eye on your waiting slots here. Only add a black block if you have extra room and a guaranteed path. The green blocks will rapidly count down as the ants consume the green tiles under the keys. Eating those specific tiles automatically collects the yellow key and the blue key. You must collect both of these keys to open up the rest of your tray.

Step 3: Unlock the padlocked blue block in your tray

Collecting the two keys triggers a massive change in your tray by destroying the yellow padlock on the blue block. This opens up your options but you must control your pace. Do not rush to pull that newly unlocked blue block right away. First you must let the ants finish off the remaining green tiles on the board. Pulling the big blue block too early will clog your waiting slots because the ants might not have a clean path to the upper blue background tiles just yet. Wait for the green active blocks to reach zero and completely disappear from your waiting slots. This specific patience guarantees you always have open slots for the exact colors you need next.

Step 4: Strip away the black headband outline

With the green outer layers gone you fully expose the orange inner pieces and the entire black outline of the headphone band. Pull your black blocks from the tray into the waiting slots. The ants will swarm up the left and right sides of the image and start eating the black border. The black border snakes all the way up and over the pink headband. Clearing this black layer is a required move because it separates the outer blue background from the inner pink heart. Let the numbers on the black blocks count down steadily. Your ants will form a long continuous line around the curve of the headphones. Always leave at least one empty slot in your waiting area to ensure your paths never jam up and cause a loss.

Step 5: Consume the orange inner ear pieces

While the ants finish working on the black border you can safely pull the orange blocks into your active slots. The orange ear pieces are completely exposed and waiting. The ants will march directly left and right to dismantle the orange sections. These orange sections hold quite a few tiles so the blocks will take a moment to count down from twenty. Just let the ants do their job and keep your hands off the tray for a few seconds. Watching the orange tiles vanish completely reveals the final bare structure of the pink headband and the pink heart. Your board is getting much smaller and the danger of dead ending your paths goes down significantly as long as you stick to the correct colors.

Step 6: Flood the board to clear the remaining blue background

Now is the perfect time to use that large blue block you unlocked earlier along with the other blue blocks waiting in your tray. Pull them up into the open waiting slots. The ants will completely bypass the pink center and head straight for the massive blue background section at the top of the screen. They will chew through the upper corners and the entire top edge of the canvas. The blue blocks have high numbers like twenty five so you will see a massive swarm of ants covering the top half of the board. Wait patiently for the blue tiles to completely vanish and the numbers to hit zero. Do not pull any pink blocks until the blue blocks are almost entirely cleared out of your slots.

Step 7: Devour the pink headband and the center heart

The only color left on your entire board is pink. The image now looks like a floating pink headband hovering right over a giant pink heart. Your tray is completely full of high number pink blocks. Pull them all into your waiting slots at the same time. The ants will pour out of the nest and completely cover the remaining tiles. They will rapidly eat through the headband and the heart simultaneously. Since pink is the absolute only color left on the board you have zero risk of blocking any paths. Watch the numbers count down from twenty and sixteen all the way to zero. The final few ants will scurry back into the nest hole leaving you with a perfectly clean board and a shiny victory screen.

Final Thought

Playing this specific board requires a steady hand and excellent timing. You must resist the urge to pull colorful blocks just because they sit at the front of the tray. By focusing strictly on opening paths and collecting the keys you keep your waiting slots clear and your ants moving forward. If you find any of these written steps hard to picture in your head I highly recommend you watch the video above this article. Seeing the ants clear the paths in real time makes the whole strategy click together perfectly.
