Colony Flow Level 1204 presents a beautiful pixel art picture of a cozy house surrounded by nature. You face a dense board full of bright colors and a tray packed with numbered blocks. I played this level from start to finish and mapped out the exact sequence you need to succeed. Follow my moves to keep your ants moving and your waiting slots clear.
Colony Flow Level 1204 Overview
What You Are Working With
The board shows a charming house with bright white walls and a large orange and yellow roof. Around the house you see green grass, bright magenta flowers, and trees with dark green leaves and dark brown trunks. Above the house is a wide sky made of light blue and dark blue tiles with fluffy purple clouds floating by. The tray at the bottom holds the numbered blocks you need to clear these tiles. This level features connected boxes. These are blocks linked together that you must pull as a group.
What It Takes to Clear Level 1204 Board
You win when every pixel art tile is gone and all ants return to the nest hole. The main challenge is managing your five waiting slots at the bottom of the screen. If you fill all five slots with blocks and the ants have no open path to reach the matching colors on the board, you lose immediately. You must carefully sequence your tray pulls so the ants always have a direct target. Every move must open up new paths for the next colors in your tray.
Colony Flow Level 1204 Step by Step Solution
Step 1: Open the lower paths by clearing the grass and flowers near the nest hole.
You start the level with the nest hole directly below the picture. The ants need immediate targets to clear the way forward. Look at your tray and pull the light green blocks and the magenta block into your waiting slots. The ants stream out of the nest and immediately start eating the light green grass along the bottom edge of the board. They also branch off to eat the magenta flowers grouped near the grass. The numbers on your waiting blocks count down rapidly as each ant grabs a piece of food. Clearing these bottom pieces creates a wide open space that gives your ants access to the house and the trees.
Step 2: Clear the front door and activate the first connected blue blocks.
With the bottom path open you can reach the dark brown front door of the house. Tap the dark brown block in your tray to move it to a waiting slot. The ants march right up the middle and consume the door tiles. This action breaks a hole directly into the center of the house structure. Now you can safely handle the connected blue blocks in your tray. Connected blocks move together and take up multiple waiting slots at once. Tap the connected blue blocks to send them up. A massive swarm of ants will wrap around the outer edges of the picture to eat the blue sky tiles. This clears a huge portion of the perimeter.
Step 3: Demolish the massive orange and yellow roof structure.
The roof of the house takes up a large chunk of the board and requires a lot of ants to clear. You will see several orange and yellow blocks in your tray. Pull an orange block into your waiting slots. The ants flow up through the hole you made at the front door and spread out across the orange roof tiles. As the first orange block counts down to zero, pull a yellow block to keep the momentum going. You want to maintain a steady stream of ants eating the roof. Doing this exposes the top layer of the white walls and gives your ants access to the purple clouds sitting directly above the house.
Step 4: Tear down the white walls and the remaining tree trunks.
Now that the roof is mostly gone you can focus on the main body of the house. The white walls form a solid block of color that you must remove. Tap the white blocks in your tray to send them to the waiting slots. The ants chew through the walls starting from the exposed edges. While the ants handle the white tiles you should also pull the remaining dark brown blocks. These will target the tree trunks on the left side of the board. Mixing these pulls keeps your ants spreading in different directions and prevents them from bottlenecking in the center of the board.
Step 5: Eliminate the purple clouds using the connected block pairs.
The purple clouds are now completely exposed at the top of the board. You will uncover a connected block pair in your tray that features purple and white blocks linked together. You must make sure you have enough empty waiting slots before tapping this pair. Once you pull them the ants will divide their attention. One group will climb all the way to the top to eat the purple cloud tiles. The other group will finish off any remaining white wall tiles. This combined action clears out two major colors at the same time and leaves only a few scattered fragments behind.
Step 6: Mop up the scattered sky and leaf pixels to finish the board.
You are now in the final phase of the level. Only small patches of color remain scattered across the board. You will see light blue tiles from the sky and dark green tiles from the tree leaves. Look at your tray and pull the matching light blue and dark green blocks. The numbers on these blocks are small now. You only need a few ants to clear each remaining section. Watch your waiting slots closely and only pull a block when you know the ants have a direct line to those specific tiles. Feed the final blocks into the slots one by one. The last few ants will run out to grab the final pieces of food. The picture completely disappears and you win the level.
Final Thought
This level requires patience and a good eye for spatial management. Managing the connected blocks is the real trick here. Always make sure your ants have a clear runway before you commit a linked pair to your waiting slots. If you find yourself getting stuck or filling up your tray too fast please watch the video above this article. Seeing the ants flow in real time will help you understand exactly when to pull each color. Keep practicing your timing and you will clear this board with ease.
