About this game
Merge Mermaids is a merge-three puzzle played with fish. You place fish on the board one at a time, and when three or more of the same fish come together they merge. The developer calls it a 2048-style game, and the aim is to keep merging for as long as you can.
Space is the thing you are managing. The developer's advice is to think ahead before playing each fish and to keep as much of the board empty as possible, since the game is over once you run out of moves. Your final score is then posted to an online leaderboard. Despite the title, the developer's description talks about fish rather than mermaids. Fish are placed by clicking or tapping, and the instructions also mention the mouse and keyboard without saying what the keys do.
How to play
Click or tap a fish to put it on the board. When three or more identical fish are together, they merge. Before each placement, think about where the fish will go and aim to leave plenty of the board empty. The game ends when no moves are left, and your score goes onto the leaderboard.

Tips
Because running out of moves ends the game, a placement that leaves empty space behind is worth more than one that fills a gap without merging. The developer's own advice is to think ahead before each fish, and keeping the board as clear as possible is the stated way to last longer.
