Ocean Merge Game
Ocean Merge is a free Suika-style merge game you can play online in seconds. Drop cute sea creatures into a glass jar, match two of the same to merge them into something bigger, and see if you can grow all the way to a whale.

What is a Suika-style merge game?
Suika Game, the “watermelon game”, made a simple idea famous: you drop round fruit into a box, and when two of the same fruit touch they merge into the next, larger fruit. The pieces roll and bounce with real physics, so the pile is always shifting. The box fills up as you go, and the game ends when the pile spills over the top. It is easy to learn in a few seconds, but planning a long chain of merges takes real skill, which is why so many people play “just one more round”.
Ocean Merge keeps everything that makes that formula fun and moves it under the sea. Instead of fruit you drop sea creatures, instead of a wooden box you fill a glass jar on a sandy lagoon floor, and the biggest prize is a blue whale instead of a watermelon.
The merge chain: from krill to whale
There are eleven creatures to discover. Each merge takes two of the same creature and turns them into the next one in the chain:
- Krill
- Clownfish
- Jellyfish
- Crab
- Starfish
- Pufferfish
- Octopus
- Sea turtle
- Otter
- Dolphin
- Whale
Only the five smallest creatures are ever dropped, and the tiny ones come most often. Everything from the pufferfish upwards has to be built by merging. When two whales meet, they vanish in a big splash and give you a 1,000-point bonus, which frees up a lot of room in the jar.
How to play
- Aim: drag your finger (or mouse) along the top of the jar. A dotted line shows where the creature will fall.
- Drop: let go and the creature falls into the jar, rolling and bouncing until it settles.
- Merge: when two of the same creature touch, they pop into the next bigger one at the point where they met. Merges can set off more merges for a chain.
- Plan ahead: the Next bubble at the top shows the creature after this one.
- Watch the line: when the pile gets close to the top, a dashed line appears. If a creature stays above it for about two seconds, the jar is full and the game is over.
Tips for higher scores
- Pick one corner for your biggest creature and build the chain next to it, from big to small. Merges then roll down into each other.
- Keep small creatures near their twins. A lone krill buried under an octopus can block a whole corner for the rest of the game.
- Use the Next preview: if a crab is coming, leave a crab exposed on the surface.
- Drop gently against the side walls when the middle is crowded. Creatures slide down the glass and fill gaps.
- Save your free Revive for a nearly full jar. It clears the top of the pile so you can keep building.
- The free Swap changes the next creature once per game. It is great for rescuing a game when the wrong creature is coming.
Cozy, fair and free
Ocean Merge has no timer, so you can take your time with every drop. Gentle ocean waves play in the background, with a mute button if you prefer silence. The Collection book fills up with every new creature you discover, and locked creatures stay as silhouettes until you reach them. Your best score and the game in progress are saved on your device, so you can close the page on the bus and continue later. The game is free, needs no download or account, and is made for phones first. It also runs on tablets and computers.
If you enjoy calm puzzles, try Glass Hexa to sort colored stacks on a hex board, Glass Bubbles to aim, match three and free the otters, Glass Blocks for a block puzzle with no timer, or Otter Cove for a cute idle game with the same otter.
