Colony Flow Level 402 Walkthrough Solution & Guides | How to solve Colony Flow 402

Colony Flow Level 402 presents a huge challenge right from the start. You see a beautiful pixel art princess, but massive blocks of chocolate cover the bottom and right edges of the board. You need to move millions of ants to eat through these chocolate mountains while slowly clearing the character portrait. It takes careful planning to avoid filling your waiting slots and failing the level. The trick is never letting those five slots fill up without a valid path on the board.

Colony Flow Level 402 Overview

What You Are Working With

The main picture features a character with dark purple hair, brown skin, and a light blue outfit. Huge chocolate blocks sit right over the bottom and the right side of the board. Chocolate covers the food tiles underneath and blocks your ants until you clear it entirely. These chocolate pieces have huge numbers on them, starting at four hundred and six hundred. You also have connected boxes in your tray at the bottom of the screen. Two blocks link together and move into your waiting slots as a pair. This means you must have a clear path for both colors in the pair, or they will sit there and jam your board completely. The tray itself contains a mix of white, brown, dark purple, light blue, and orange blocks.

What It Takes to Clear Level 402 Board

You need to constantly pull blocks that match the exposed edges of the picture while always keeping ants working on the chocolate. The chocolate takes a massive amount of matching colored blocks to finally break down. You clear the board by managing your five waiting slots perfectly. You must pull colors in the exact right order so the ants never stop marching. A dead end happens when you pull a color that has no open tiles, causing the block to sit forever in the waiting slot. Do that five times and the game is over. The level ends when every piece of chocolate shatters and the ants carry the final pixel art tiles back to the nest hole at the bottom.

Colony Flow Level 402 Step by Step Solution

Step 1: Open the bottom edges by matching the white border tiles.

Your very first moves must target the white background tiles at the bottom left of the portrait. Pull the loose white blocks from your tray into the waiting slots. The ants will stream out of the nest hole and start marching up the left side of the board. This matters because you need to expose the actual colored tiles of the character to give your ants more paths. Do not touch the connected boxes yet. Just focus on letting the ants clear out the white border. Watching the ants open up the left side gives you a reliable path that keeps your slots from jamming. The numbers on your white blocks will drop quickly as the ants eat away the border.

Step 2: Attack the massive bottom chocolate block with brown tiles.

Once the left path opens up, you need to start working on the massive chocolate pieces. Pull the single brown blocks from your tray. The ants will immediately target the bottom chocolate block that starts with four hundred points. This chocolate is a massive roadblock and you must constantly chip away at it. As the ants carry pieces away from the chocolate, the number slowly ticks down. Keep an eye on your waiting slots. You want at least one brown block active at all times to keep steady pressure on that bottom barrier. If you ignore the chocolate, you will run out of space later. The ants form a tight line from the nest hole directly to the chocolate edge. You can watch the brown block numbers decrease as each ant grabs a piece.

Step 3: Bring the connected boxes into play carefully.

Now you have to handle the connected boxes in your tray. You will see a white block connected to a brown block. Pull this pair up into your waiting slots. Since you already opened a white path on the left and a brown path on the bottom chocolate, the ants can access both colors immediately. This is the trick to handling connected boxes safely. Never pull a connected pair unless you know both colors have an open path on the board. The ants will divide their attention between the white border and the brown chocolate. This clears the connected blocks efficiently and frees up two spots in your waiting area at the exact same time.

Step 4: Introduce dark purple blocks to clear the character hair.

The ants moving up the left side will eventually hit the dark purple hair of the character. When you see the dark purple tiles become exposed, pull a dark purple block from your tray. The ants will march all the way up the left edge and start eating the hair. This creates a brand new path and spreads your ants across the board. Having multiple active paths is the best way to keep your five waiting slots empty. You now have ants working on the white border, the dark purple hair, and the brown chocolate all at the same time. Pulling a dark purple block here guarantees that the ants stay busy and your waiting area stays clear.

Step 5: Shift focus to the right side chocolate block.

As the bottom chocolate block shrinks, you will gain access to the right side of the board. This right side features an even bigger chocolate block starting at six hundred points. You need to pull more brown blocks to send a new stream of ants toward this massive obstacle. It takes patience to watch that high number slowly decrease. Keep feeding brown blocks into the waiting slots whenever you have a free space. You must maintain a steady flow of ants attacking the right side chocolate or you will run out of blocks later in the level. The longer you wait to attack the right side, the harder the level becomes because that six hundred takes a huge amount of time to reduce.

Step 6: Clear the light blue dress and skin details.

With the ants busy on the outer edges and the chocolate, the center of the character portrait will open up. The ants will expose the light blue tiles of the dress and the brown tiles of the skin. Check your tray for light blue blocks and single brown blocks. Pull them into the waiting slots to send ants right up the middle of the board. You will also see small details like the yellow and orange tiles for the jewelry. Pull those specific colors only when the ants clear the tiles directly touching them. Keeping the center paths active prevents the board from dead ending and keeps your slots clear while the ants break down the remaining chocolate on the right.

Step 7: Destroy the last remaining pieces of chocolate.

Eventually the continuous stream of ants will reduce the massive chocolate blocks to zero. The moment the chocolate shatters, it reveals the hidden picture tiles underneath. This gives you tons of new paths to work with. Immediately look at the newly revealed colors and pull matching blocks from your tray. You will likely see more white background tiles and pieces of the light blue dress. Match these quickly to keep the ants moving and to clear out the waiting slots that were held up during the final chocolate phase. The ants will flood the newly opened area and finish clearing the lower half of the portrait.

Step 8: Clean up the isolated dark purple hair chunks.

The character portrait is almost completely gone now. You will be left with a few disconnected chunks of dark purple hair at the very top of the board. Pull your remaining dark purple blocks into the waiting slots. The ants will form long lines marching all the way to the top corners of the screen. Make sure you do not overload your slots with white blocks while you wait for the ants to reach the top. Pull exactly what you need for the hair first. The travel time is longer now since the ants have to walk across the whole empty board, so patience is required to let the slots empty naturally.

Step 9: Match the final white background tiles to win.

The last few tiles on the board will be the scattered white background pieces near the top edges. Your tray will be full of white blocks with different numbers on them. Pull them into the waiting slots one by one. The ants will rush out to clean up these final pieces. Since there are no more obstacles or chocolate left, the ants will finish the job quickly. Fill your slots with the remaining white blocks and watch the swarm clear the board. Once the final white tile vanishes, the board clears completely and you win the level.

Final Thought

Beating this board requires excellent timing and constant pressure on those massive chocolate blocks. You have to balance clearing the character portrait with slowly breaking down the obstacles. If you find yourself getting stuck on how to handle the connected boxes or the right side chocolate, take a moment to watch the video above this article. Seeing the exact timing of when to pull each color will help you master the board and keep your waiting slots completely clear.
