Welcome to Colony Flow Level 256. This puzzle presents a colorful pixel art picture of two juicy watermelon slices. A massive colony of ants waits inside the nest hole at the bottom of the screen. You feed the colony by pulling colored numbered blocks from the tray. You will need careful tray management to clear the board without filling your five waiting slots. Let me walk you through exactly how to beat this stage.

Colony Flow Level 256 Overview

What You Are Working With

The board features a large picture made of several distinct colors. The main body of the watermelon slices uses bright red and dark red tiles for the flesh. Black tiles act as the seeds scattered throughout the fruit. The bottom edges form the rind using a thick layer of white tiles followed by light green and dark green tiles. You will also notice two Lock and Key mechanics embedded in the picture. A yellow key sits in the upper left area of the right slice. A blue key rests near the bottom middle of the left slice. Up in the top left corner of the left slice, a Hungry Door labeled with a ten blocks a large section of the board. Down in your tray, you have multiple layers of numbered blocks matching the board colors. You will also see a yellow lock and a blue lock sitting in the tray. These locks prevent you from reaching the blocks underneath them.

What It Takes to Clear Level 256 Board

Clearing this board means eating every single tile and satisfying the Hungry Door. You must guide your ants from the nest hole to the matching tiles by pulling blocks from your tray. Because the tray contains locks, you must prioritize reaching the keys on the board first. The core challenge comes from the five waiting slots at the bottom of the screen. When you tap a block in the tray, it moves up into one of these slots. If you pull a block that your ants cannot reach, that block will sit in the slot permanently. It takes up twenty percent of your usable space. If you make this mistake five times and all five slots fill up with no valid moves, you lose the level instantly. You win the game when every key is collected, the tray locks vanish, the Hungry Door is fully fed, and the ants carry away the final tile.

Colony Flow Level 256 Step by Step Solution

Step 1: Start with the bottom rind to open the initial pathways.

At the beginning of the puzzle, the ants only have access to the bottom edges of the watermelon slices. You need to pull blocks that match these outer layers. Select a white block and a light green block from your tray to get things moving. The ants will stream out of the nest hole and begin clearing the white inner rind and the green outer rind. Watch the numbers on your tray blocks drop as the ants consume the tiles. This action pushes the front line deeper into the watermelon. Keep a close eye on your five waiting slots and avoid pulling red blocks right away. The ants cannot reach the red flesh until they chew through the rind.

Step 2: Transition into the dark red shading and red flesh.

Once the bottom rind begins to break apart, the red sections become exposed. Now you can safely pull a red block and a dark red block into your waiting slots. The colony will divide its attention between finishing the green rind and starting on the red fruit. Pulling a dark red block helps here because the dark red tiles form a thick layer just above the rind on the left slice. By clearing the dark red tiles, you open massive pathways into the center of the slices. Your tray will reveal more blocks as you use the top layers. Always make sure the ants have an open route to the colors you select to keep your slots from jamming.

Step 3: Carve a path directly toward the blue key.

With the red flesh exposed, you must prioritize grabbing the blue key located near the bottom middle of the board. Look at your tray and find the blue lock restricting your access to the blocks underneath it. Pull another red block into your active slots to clear the tiles immediately surrounding the blue key. As the ants eat the red tiles touching the key, they will collect it automatically. Collecting the blue key immediately shatters the blue lock in your tray. This frees up good space and gives you access to fresh blocks. Managing this unlock early prevents your tray from becoming stagnant and keeps your block options varied.

Step 4: Push the colony upward to secure the yellow key.

After dealing with the blue key, shift your focus to the upper section of the right watermelon slice. The yellow key rests high up in the red flesh. You need to carve a channel through the middle of the slice to reach it. Pull a red block and a white block to clear the way. The white blocks are necessary because some white rind tiles extend all the way up the sides of the slices. As your ants march higher, they will expose the red tiles touching the yellow key. Once they consume those neighboring tiles, the yellow key activates and shatters the yellow lock in your tray. Getting both locks out of the way is a huge help for your tray management.

Step 5: Process the black seeds scattered across the fruit.

Now that your tray is fully unlocked, you can handle the black tiles acting as watermelon seeds. These seeds sit alone inside the red flesh of both slices. Pull a black block into your waiting slots. Because you already cleared much of the surrounding red fruit, the ants have clear paths to reach multiple seeds at once. The black block will count down rapidly as the ants swarm the seeds and carry them away. Clearing the seeds connects the different cleared pockets of the board together. This creates large open areas for your ants to travel through. It also exposes the final thick sections of red and dark red tiles near the top edges.

Step 6: Clear the surrounding tiles to access the Hungry Door.

Look at the top left corner where the green Hungry Door sits. It requires ten feeds to open and resolve. Before the ants can interact with it, you must clear the tiles blocking its entrance. Pull a dark red block and a white block to eliminate the final barrier tiles around the door. Once the path is totally clear, the ants will start pouring directly into the Hungry Door. You will see the number ten slowly tick down to zero as the colony feeds it. Do not pull unnecessary blocks into your slots while the ants are busy feeding the door. Let them finish the job so the door fully resolves and removes itself from the board completely.

Step 7: Clean up the remaining outer rind and upper corners.

With the Hungry Door gone and the keys collected, only a few stray tiles remain on the board. You will likely see some light green and white tiles lingering on the far left and right edges. Pull the corresponding light green and white blocks from your tray into your slots. The ants will take a long march around the empty space to reach these perimeter tiles. Keep your slots managed carefully during this final phase. You only have a few tiles left on the screen. Pulling a massive block value might leave a block sitting in your slots forever. Only pull what you need to finish the remaining pieces.

Step 8: Finish the final red pieces to complete the puzzle.

The last few tiles will be scattered red and dark red pieces at the very top of the watermelon slices. Check your tray for the final red blocks and pull them into your remaining slots. The colony will rush to the top corners and eat the last pieces of the fruit. Watch your slots empty out completely as the final numbers tick down to zero. The board will be totally clear. You have successfully managed your tray, unlocked the keys, fed the Hungry Door, and solved the level.

Final Thought

Colony Flow Level 256 demands patience and very careful path management. You must prioritize the keys to keep your tray options open and you must never pull blocks that your ants cannot reach. If you get stuck on any particular step or cannot figure out the best path to the Hungry Door, I encourage you to watch the video above this article. The visual walkthrough will show you the exact timing for every single block pull.
