About
Dive into a colorful merging challenge in Fish Sticker Merge, a drag-and-merge puzzle game where careful planning is the key to keeping your tank under control.
Your objective is to create and collect the target fish displayed at the top of the screen. Drag identical fish together, merge them through different stages, and build the exact fish required to complete the level.
Every fish begins as a white version. Combining two matching white fish creates one black fish. Combining two matching black fish produces a colored fish. Finally, merging two identical colored fish collects that species when it matches one of your current targets.
Clear every target fish to finish the level and continue your collection. Each successful merge brings you closer to victory, but it may also trigger a refill that adds more fish to the tank. Think ahead, keep matching fish close together, and avoid filling the board with pieces that are difficult to combine.
Space is limited, and every move matters. A fish that is dragged outside the playable area ends the run. Allowing too many fish to pile up and overflow the top of the tank also causes a game over. Keep the tank organized and create useful merging paths before space runs out.
As you progress, you can unlock special reward actions that help during difficult situations. Visit the Fish Book to view the species you have already collected and continue discovering new fish throughout the game.
How Merging Works
Merge two identical white fish to create one black fish.
Merge two identical black fish to create one colored fish.
Merge two identical colored fish to collect the target species.
Collect every fish shown in the target display to complete the level.
Plan Your Strategy
New fish are added after several successful merges, so the tank can become crowded quickly. Keep identical fish near each other and avoid separating useful pairs.
Focus on the current targets instead of merging randomly. Creating unnecessary fish may take up valuable space and make later moves more difficult.
Watch the upper part of the tank carefully. When the fish pile reaches the top, the level ends.
