Colony Flow Level 519 Walkthrough Solution & Guides | How to solve Colony Flow 519

Welcome back to another puzzle guide. Colony Flow Level 519 throws a massive wall of tiles at you right from the start. You need to clear a large picture of a green fish completely surrounded by a thick orange background. You must carve through the outer layers quickly before your tray fills up. I played through this level several times to find the absolute safest sequence for your block management. I will show you exactly how to manage your block queue to secure a win without getting your colony stuck.

Colony Flow Level 519 Overview

What You Are Working With

You face a giant pixel art fish made of bright green and light green tiles. A solid dark blue outline wraps entirely around the fish shape to form a hard border. Inside the fish body you will see a large section of white tiles that look like square scales. You will also spot smaller details in red and purple filling out the lower fins. The entire fish shape sits tightly packed inside a massive orange background that dominates the screen. Down in your tray you start with large numbered blocks including an orange 40 block and a green 30 block. You will also notice a Hidden Box block in the tray marked with a large question mark. This block hides its true color until you place it in the waiting area and give it an open path to a matching tile.

What It Takes to Clear Level 519 Board

You win the level when you clear every single tile from the picture and all your ants return safely to the nest. You lose if you fill all five waiting slots with blocks that have no clear path to their matching tiles on the board. The ants spawn from a single hole at the bottom of the screen. They must eat their way steadily from the bottom row all the way up to the top. If you pull block colors for the top of the fish too early those blocks will just sit in your waiting slots and block new moves. You must strictly follow a bottom to top clearing pattern to ensure your waiting slots remain empty and your ants stay active.

Colony Flow Level 519 Step by Step Solution

Step 1: Pull the large orange block to clear the bottom corners

You need to create walking space for your colony right away before doing anything else. Tap the orange 40 block from your tray to move it into your first waiting slot. The ants pour out of the central nest hole and immediately swarm the orange tiles along the bottom edge of the board. The orange background forms the outermost layer of the puzzle and blocks everything else. Removing these bottom orange tiles creates wide open paths leading up to the bottom fins of the green fish. This early move keeps your first tray slot active and prevents an immediate traffic jam in your queue.

Step 2: Target the bottom green fins to expose the outline

With the bottom corners perfectly clear your ants can now reach the lower exterior sections of the fish. Tap the green 30 block to send your ants to work on the large bottom fins. The green 20 block and green 23 block will also appear in your tray during this phase. Pull them up into your waiting slots as space allows. As the ants consume the green tiles the numbers on your tray blocks tick down rapidly. You will see the thick dark blue outline tiles become fully exposed on the bottom half. Pulling these green blocks opens up the physical space you need to start dismantling the structural outline of the fish.

Step 3: Remove the dark blue outline to open the belly

The dark blue tiles form a hard barrier around the inner colors of the fish. Select the dark blue 25 block from your tray to send your ants forward. The colony marches directly through the empty space left by the orange and green tiles to reach this dark blue border. Clearing this outer border unlocks direct access to the softer interior colors of the fish belly. You must wait for the ants to finish this block entirely before crowding the queue. Rushing this phase and pulling too many interior blocks will instantly fill your five waiting slots and end your game.

Step 4: Place the hidden box to reveal its target color

Your tray contains a block marked only with a white question mark. This acts as a Hidden Box block that conceals its true color until it has a valid open path to move on the board. Now that you have carved a wide path through the bottom dark blue outline you can safely bring this hidden block up into your waiting slots. Once it hits the waiting area the block reveals its actual color and the ants immediately find the matching tiles on the board. Playing this hidden block at this specific moment guarantees the ants have a clear route. Getting it out of the way now keeps your tray perfectly organized.

Step 5: Hollow out the red and light green underbelly

The lower half of the fish contains red detail tiles and a light green belly section. Pull the red 26 block and the light green 31 block into your queue. The ants flood into the open belly of the fish to consume these specific tiles. The red and light green sections sit very close to your nest hole at the bottom of the screen. The ants travel very short distances to reach these tiles so the blocks will count down and vanish from your waiting slots incredibly fast. You keep your queue moving smoothly by focusing on these easily accessible colors.

Step 6: Attack the dense white scales in the center

A massive block of white tiles sits right in the middle of the fish body. Bring up your white 3 block and white 5 block to target this area. The ants push deep into the center of the picture to eat away these dense white scale tiles. This step completely hollows out the core of the fish. Leaving this massive white section for later will block your ants from reaching the upper green tiles effectively. Clearing the center out right now gives your colony a straight open highway right up to the top half of the board.

Step 7: Sweep the massive upper orange background

The top half of the picture still contains a huge amount of orange background tiles. Look at your tray and you will see massive numbers waiting for you like the orange 34 block and orange 38 block. Pull these large orange blocks from your tray into your waiting slots one at a time. The ants now have a completely clear vertical path right through the empty space inside the fish to reach the top corners. They stream up the middle and wrap around the remaining green head to devour the upper background. You must clear this top orange layer before you attempt to finish the green fish head to avoid blocking your colony.

Step 8: Dismantle the green head and white eye

Only the green face and the white eye remain near the top of the screen. Tap your smaller green blocks like the green 21 block and green 11 block. The ants swarm the head of the fish from all sides. Bring up the final white blocks from your tray to clear the single eye tile section. The waiting slots remain perfectly safe because the ants have direct physical access to every single remaining tile on the board. The green tiles vanish quickly as the ants focus entirely on this small remaining section.

Step 9: Clear the final blue outline to win the level

A few scattered dark blue outline tiles sit at the very top edge of the board. Pull the last dark blue blocks into your active queue. The ants rush to the top and eat the final border pieces. The board becomes completely empty and the remaining ants dive back down into the nest hole. You clear the level and secure your victory by maintaining perfect queue management from start to finish.

Final Thought

Level 519 tests your patience and your ability to read the physical layout of the board. You win by strictly clearing the outer layers before attacking the core of the picture.
