A few fun mermaid games for kids are "Swimming With Dolphins," "Mermaid World" and "Mermaid Aquarium Coloring." Players find these mermaid games online at GirlsGoGames.com for free as of July 2015.
In "Swimming With Dolphins," the players get the mermaid ready for her swim with the dolphins. The player gets to select everything from the tail and fin color to the hairstyle and accessories. Players drag and drop desired options over to the mermaid, and when the mermaid is ready, they see the mermaid and dolphin together. The player can save the file or print out a picture of the mermaid and dolphin.
"Mermaid World" allows a player to create the perfect undersea world for a mermaid. Players select among the different fish, clamshells and visitors to the undersea world, and then they pick an item to add to the world and drag the item where they want it. The player can add the same piece to multiple locations.
Players get to color their own mermaid pictures in "Mermaid Aquarium Coloring" by taking the paintbrush, clicking on the desired color and then clicking on the area to be colored. The color fills into the space automatically. The game allows players to erase small areas or the entire coloring page. When finished, the player can print a copy.
