Colony Flow Level 31 Walkthrough Solution & Guides | How to solve Colony Flow 31

Colony Flow Level 31 gives you a giant pixel art watermelon slice on a stick to clear away. You need to manage a massive block of hidden food covering the left side of the shape. I found this level requires careful sequencing to reveal those secret tiles without jamming your five waiting slots. You will need to dig through the bottom rind and the stick to open the pathways. This level tests your patience and your ability to read the board ahead of time. You cannot just guess and pull blocks randomly. Every single move has to serve a specific purpose.

Colony Flow Level 31 Overview

What You Are Working With

Let us look at the board layout. The main picture is a bright red watermelon popsicle with a thick black outline and scattered black seeds inside. The base features a yellow wooden stick and a curved dark green and light green rind section. A large light blue background surrounds the entire treat making up a huge portion of the total tiles. The trickiest part is the large rectangular block of grey tiles with question marks on the left side. These are hidden food tiles. They only reveal their true colors when your ants clear the regular tiles touching their outer edges. The tray at the bottom is packed with high number blocks. You have twenties and eighteens in light blue along with heavy red and black blocks waiting to be used. The sheer volume of numbers means you must be efficient with your clear paths.

What It Takes to Clear Level 31 Board

To beat this puzzle you must peel away the outer layers systematically to unlock the hidden section on the left. The grey tiles will not accept any ants until they are fully exposed by clearing the pieces next to them. You have to send light blue ants to eat the bottom background tiles first. This initial push creates a clear path to the yellow stick and the dark green rind. As those bottom pieces vanish the grey question marks begin to flip and show their real colors. You win when every single tile is gone and your waiting slots never completely fill up with blocks that have nowhere to go. You must constantly balance the colors in your active slots so the ants always have an open path to a matching tile. A single mistake placing a high number block too early will clog your tray and force a restart.

Colony Flow Level 31 Step by Step Solution

Step 1: Focus on the bottom light blue background to create an opening

Your very first moves must target the light blue background tiles right above the nest hole. Pull the twenty and eighteen light blue blocks from your tray into the waiting slots. The ants will stream out and immediately start eating the bottom edge of the board. This is crucial because it clears the physical barrier blocking the yellow stick and the dark green rind. As the light blue ants clear the space you will notice the first few hidden food tiles on the bottom left corner start to unlock. They reveal more light blue background tiles and parts of the black outline. Keep pulling light blue blocks until the bottom path is wide open. You never want to leave a slot occupied by a color that cannot move.

Step 2: Clear the yellow stick and dark green rind to expose more hidden tiles

With the bottom edge cleared you now have access to the base of the popsicle. Pull a sixteen yellow block and a seventeen dark green block into your open slots. The yellow ants will chew through the wooden stick while the dark green ants attack the outer rind. This action works like a wedge driving up the middle of the board. Every yellow and green tile that disappears forces the adjacent grey hidden tiles to unlock. You will see more black outline tiles and some light green inner rind tiles appear on the left side. Keeping these central paths active prevents your slots from jamming because the ants always have fresh targets flowing down from the top.

Step 3: Deploy black and light green ants to maintain momentum

Now that you have exposed the black outline and the light green inner rind you need to match them. Tap an eighteen black block and a ten light green block from the tray. The black ants will split up to eat the exposed outline on both the left and right sides. The light green ants will focus on the inner rind right below the red watermelon flesh. This step fully breaks the barrier between the bottom of the board and the massive red center. It also peels back another major layer of the hidden food section. Watch the left side closely because a bunch of red tiles will finally reveal themselves from behind the grey covers.

Step 4: Start clearing the exposed red flesh and continue unlocking the left side

You finally have access to the main body of the watermelon. Bring up a seventeen red block and a fifteen red block to get your red ants moving. They will march straight up the middle and start devouring the red tiles. At the same time you should keep a light blue block active in your slots. The left side hidden section is still turning into light blue background tiles as the red center shrinks. Letting the red and light blue ants work at the same time keeps the left side unlocking smoothly. Never pull too many red blocks at once or you will jam the slots while the ants travel up the long vertical path.

Step 5: Send light blue ants up the right side to flank the picture

While the left side is slowly revealing itself you need to handle the right side of the board. Pull a twenty light blue block and watch the ants travel up the right edge. They will eat away the large chunk of background separating the watermelon from the edge of the screen. This is a great way to use up big light blue blocks without clogging the middle path. The red ants are still busy in the center so the right side offers a completely separate highway. This dual path strategy ensures your waiting slots stay clear and the ants flow without interruption. You always want multiple colors working in different zones.

Step 6: Attack the remaining black seeds and the top outline

As the red flesh gets eaten away the black seeds scattered inside the watermelon become exposed. You will also see the top black outline become reachable. Bring a fifteen black block into your active slots. The black ants will weave through the red gaps to grab the seeds and march all the way to the top right curve of the outline. You must time this well. If you pull the black block too early the ants will have no path to the upper seeds and your slot will stay blocked. Wait until the red ants have chewed a clear path through the middle before calling the black ants to clean up the seeds.

Step 7: Clear the final hidden tiles on the top left corner

The very last grey question mark tiles are located at the top left of the board. By now your red ants have eaten enough of the center to unlock them. They will turn into the final pieces of the black outline and the top left light blue background. Tap your remaining light blue and black blocks from the tray. The ants will rush the top left corner and dismantle the last piece of the outline. The whole hidden section is now completely resolved. You just need to mop up the remaining background tiles circling the top boundary of the board.

Step 8: Flood the board with light blue to finish the background

The only things left on the board are the top light blue background tiles and a small cluster of red near the right edge. Tap your last big light blue blocks and your final fifteen red block. The screen will fill with ants spreading out to every corner. The red ants will polish off the last bit of the watermelon body. The light blue ants will sweep across the very top row and the upper left gap. Because the paths are entirely open the ants will move fast and clear the board in seconds. Your slots will empty out rapidly as the final pieces vanish.

Final Thought

Colony Flow Level 31 teaches you how to patiently dismantle a barrier to reveal hidden elements. You cannot rush the left side of the board. You must let the natural progression of the bottom tiles dictate when the hidden food unlocks. Always keep your eyes on the adjacent tiles and plan your tray pulls based on what is about to open up. If you pull a color before its path is ready your slots will jam and end your run. Take your time and let the ants do the heavy lifting. I encourage you to watch the video above this article if any step is hard to follow in text. Seeing the ants trace these paths makes the whole strategy crystal clear.
