Fishdom

Yes, Fishdom is a free-to-play game on mobile platforms, supported by in-app purchases for premium currency, extra moves, and power-ups. The game was originally released for web browsers and PC by Playrix in 2008 before expanding to iOS and Android, where it adopted the freemium model typical of mobile puzzle games.

Fishdom was developed and published by Playrix, the game company founded by brothers Igor and Dmitry Bukhman, who are also known for the massively successful 'Homescapes' and 'Gardenscapes' franchises. Playrix has grown into one of the largest mobile game publishers in the world, with Fishdom being one of its earliest and longest-running titles.

In Fishdom, players complete match-three puzzle levels to earn in-game currency, which they then spend on fish, decorations, and equipment for customizable virtual aquariums. The aquarium-building meta-progression is the game's defining feature, distinguishing it from standard match-three games by giving players a creative goal beyond simply clearing puzzle boards.

Fishdom on mobile requires an internet connection for most features, including in-app purchases, social functions, cloud saves, and event participation. The original PC version from 2008 offered more traditional offline play, but the dominant mobile versions are designed around always-online connectivity consistent with modern free-to-play game infrastructure.
