Colony Flow Level 518 Walkthrough Solution & Guides | How to solve Colony Flow 518

Colony Flow Level 518 brings a beautiful pond scene straight to your screen and challenges you with some tricky block combinations. I am Liam Stone and I play every single puzzle to give you the most accurate walkthrough possible. This puzzle demands careful planning because the tray is full of connected boxes that can quickly ruin your game. You will need a solid strategy to keep your ants moving without jamming your board.

Colony Flow Level 518 Overview

What You Are Working With

The puzzle board displays a vibrant pixel art picture of a koi pond. The vast majority of the board is a massive light blue background representing the water. Floating in this water are several fish constructed from orange red white and purple tiles. You will also see large green lily pads decorated with bright pink and red flowers. Dark blue tiles create thick outlines around the fish and the plants to give them shape. The tray at the bottom holds your numbered blocks. This level features connected boxes in the tray heavily. These are two or more blocks linked together by a thick line. When you pull one connected box the linked box comes with it. They drop into your waiting slots as a group and take up multiple spaces instantly.

What It Takes to Clear Level 518 Board

Your primary goal is to clear every single tile from the board to win. The ants must consume the entire picture from corner to corner. The main challenge comes from the five waiting slots located at the bottom of your screen. If you pull too many blocks and fill all five slots without an open path to the board you lose the level immediately. You must always verify that your ants have a clear route to a matching color. Success requires you to balance large single blocks with the dangerous connected boxes so your waiting slots never jam. Every move you make must keep at least one path open for the colony to clean the board.

Colony Flow Level 518 Step by Step Solution

Step 1: Clear the outer edges of the board by deploying light blue blocks

Start your game by targeting the massive amount of light blue water covering the board. The tray offers several light blue blocks with large numbers to help you clear this liquid background. Pull a light blue block into your first waiting slot. The ants will immediately pour out of the nest hole and begin eating the water tiles along the outer edges of the picture. Pull a second light blue block to keep the momentum going strong. This action carves wide open paths around the outside of the fish and the lily pads. Opening the outer edges early gives your ants multiple angles of attack for the inner tiles. You want the ants to have maximum room to navigate around the complex fish shapes.

Step 2: Manage the first connected boxes to carve into the large fish

As you clear the top layers of the tray you will uncover your first set of connected boxes. You will see an orange block linked directly to a dark blue block. Before you pull these connected boxes you must ensure both colors have exposed tiles on the board. Look at the orange fish and the dark blue outlines surrounding the plants. Both of these colors are completely ready to be cleared. Pull the connected boxes down into your waiting slots. The ants will split up into two working groups. One group will march toward the orange fish body while another group eats away the dark blue borders. This clears space rapidly while keeping your waiting slots flowing freely.

Step 3: Break down the red and orange sections of the central fish

The center of the board features a large fish made mostly of orange and red tiles. You must pull a red block into your waiting slot to start clearing the body. The ants will rush to the red sections and begin dismantling the middle of the big fish. Follow this move by pulling an orange block to keep your colony busy. The ants will consume the surrounding orange tiles and expose the dark blue lines hidden underneath. Managing these two bright colors together is highly effective for clearing space quickly. As the red and orange tiles vanish you will reveal the inner dark blue lines and the nearby green lily pads. Always verify that the ants completely finish their current block before you pull another color.

Step 4: Eliminate the white and purple details on the left side

Focus your eyes on the small fish positioned on the middle left side of the pond. This fish contains white and purple tiles that stand out from the rest of the picture. Pull the white block from your tray to send your ants toward this specific fish. The ants will march over the completely cleared water sections to reach the white fish scales. Once the white block counts down to zero you can pull the dark blue blocks that outline this area. Clearing these smaller details early prevents them from blocking your progress later in the stage. The board will now look much emptier on the left side and give your ants even shorter travel times.

Step 5: Remove the green lily pads to open massive spaces on the right

Now shift your attention to the large green lily pads scattered across the right side of the board. You have completely open paths to these plants because you cleared the water around them in the first step. Pull a green block down into your open slot. The ants will swarm the green leaves and rip them away from the board. The numbers on the green block will tick down very quickly as the large plants disappear. Next you should pull a red block to clean up the red flowers resting on top of the lily pads. Removing these giant plants opens massive holes in the right side of your picture and makes navigating the final stages much easier.

Step 6: Navigate the tricky red and dark blue connected blocks

Another dangerous set of connected boxes will appear in your tray around this time. This pair features a dark blue block linked to a red block. Check the board to verify your exact targets before you touch them. You should have dark blue borders around the top right fish and red tiles on the remaining flowers. Pull the linked pair into your tray to activate them. The ants will travel across the empty space to eat the dark blue lines and the red petals simultaneously. Watch your waiting slots very carefully during this maneuver. Do not pull any extra blocks until this linked pair completely clears out of your tray.

Step 7: Clear the yellow and orange linked blocks to finish the top right fish

As you reach the final layers of the tray you will encounter yellow blocks linked to orange blocks. The yellow tiles make up the small delicate details on the last remaining fish in the top right corner. Pull the yellow and orange linked pair into your tray. The ants will rush to the top right corner to consume the yellow fins and the orange body segments. You might only have one or two waiting slots open at this exact point in the puzzle. Keep your focus entirely on that top right corner. Do not touch any light blue blocks or green blocks until that fish is completely gone and your slots empty out.

Step 8: Clean up the final water and plant tiles to empty the board

Only a few small clusters of tiles remain on the board at this final stage. You will see some scattered light blue water tiles and a few green plant bits near the edges. Pull your remaining light blue blocks into your available slots. The final light blue block will summon a massive swarm of ants to wash over the last pieces of the pond. Pull the final green and orange blocks to finish the job entirely. The ants will eat the very last pixels on the screen and retreat into their hole. Your waiting slots will empty out completely and the level will end in a satisfying victory.

Final Thought

This level tests your ability to plan ahead and manage dangerous linked blocks. Take your time and always verify your paths before pulling a new color into your tray. If any specific move feels confusing to read you can watch the video above this article to see exactly how I cleared the board.
