[b]Merits:[/b] ▪ It looks pretty ▪ Supports touch screens ▪ You can unlock more variety [b]Flaws:[/b] ▪ Not a game, more of a screensaver ▪ The unlocks feel very similar ▪ Limited pond customisation [b]Verdict:[/b] For the price I paid, I got a decent screensaver. However, the same effect could be achieved with a YouTube video. I feel like the software would need a lot more options to work as a fish tank simulator, which I though it was at first.

A beautifully crafted koi pond simulation, created with great care and a focus on relaxation and slowing down in everyday life.

A very chill and relaxing game that I got to play with my 6-year-old. My Koi is a simple, calming experience that lets you slow down, enjoy the atmosphere, and just watch your pond grow. A charming little game that’s easy to pick up and enjoy.

Game is really realaxing and cool. Nice Koi Fishes. It would be great if developer updates game and adds options like fish breeding and selection so that we can transfer fish from ponds like we want and to organize them.
Recommended Mar 3, 2026
I'm not sure how much you can call this a game but it is fun. I do wish there were additional features like breeding and even more ponds/pond decorations. Also it's been a bit slower getting to the next size of fish to unlock more types of koi. Despite that it's very relaxing and the fish are very well animated. For those new to the game, the only thing you really have to do is feed fish once a day. They won't die if not fed but I did read somewhere that if it goes on too much it can stunt growth eventually.
