Can you help please?


Recently the Sounds & Music have stopped. I’ve tried toggling back and forth on the settings buttons for both but it doesn’t help. Sounds & volume are fine on everything else in my phone, it’s just my Zen Koi 1 game. It’s no huge deal & certainly doesn’t take away from my huge love for this or my Zen Koi 2. They are both in my most top favorite apps I own. I really enjoy the music though and find it very soothing. I’m kind of missing it and my fishies satisfying little snacking sounds. 😄 Thank you for these lovely games!

Update: Thank you SO much! I feel so silly. I hadn’t even noticed that tiny button. ☺️ I must have switched it off when I removed my case to charge my phone. Both of these games are my absolute favorites, and you, the Developers, ROCK!!! Thank you for your time and help. 👍🏻⭐️⭐️⭐️⭐️⭐️

Hi there! It could be due to the side switch on your device. If you mute the device using the side switch, then later go to settings and change the slide button to lock rotation, the apps muted with the switch will stay muted even if your volume is up.
To fix this, go to the settings menu and make the side switch “mute” again. Then use it to mute and unmute the device.



I just got this game recently and I’m “hooked”-terrible pun intended. It’s very relaxing and fun, but I have just one problem-it seems like in order to even have a decent ‘collection’ of fish you need more slots-slots cost pearls-pearls cost real money, not to mention the fact that once you buy one slot the price goes up in seemingly incriminates of ten. Oh they do have videos you can watch to earn pearls if you don’t want to spend real money (like me, ballin on a budget) but you only get ONE pearl per video. I play plenty of other games that use this same video system and they give out more than just 1 of anything, making it still a bit grindy but not downright impossible. I have tons of baby fish to hatch and no slots for them, so just a suggestion-maybe give at least 3 to 5 pearls per video?

Hi there! There are more ways we give out free pearls as rewards: 1) ascending koi to dragons 2) completing koi and dragon collections 3) achieving awards 4) daily rewards and 5) occasionally when you swim past a lotus flower.

So, I downloaded this game to play for myself. It’s really fun and the graphics are really good. Unlike other games, I can’t get bored. But one day, my cousins decided they could just play on my account and now I’m already at level 10, when I only got to play ten minutes. I tried deleting it and telling them no, changing the passcode, and hiding the iPad, but they keep on finding it! When I deleted it, I got it again in hopes that it would start over, but it didn’t. Is there any way that I can lock a certain app with a passcode or delete the actual data? I know that data save is useful, but it is really annoying in my situation. Please reply! But don’t change the gameplay!
