Fishdom made a big splash when it debuted in 2008 – and with updates adding an ocean’s worth of content, this match-3 puzzler is still going strong. Here are three reasons plunging into Playrix’s aquatic classic is still so invigorating:

Solving puzzles gives you resources to spend on upgrades and decor for your collection of aquariums – but they need fishy friends to bring them to life! Recent updates have added blue marlin, rainbow fish, zebra lionfish and other colourful sea creatures. How many can you catch?

There’s more to this game than tending turtles and placing coral castles. Blaze trails through undersea jungles and explore temples with Iguana Jones in extra-challenging match-3 levels... if you dare.

Tons of new aquariums and decorations have emerged over the years. Add an animated geisha statue to the Mythical Japan aquarium, make mighty Aphrodite the centrepiece of a Heroic Olympus tank – there’s no wrong choice!
