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.

AVOID: Ads & IAP & constant crashing

Zen Koi has had premium currency in-app-purchases (IAP) for as long as I've had the app. A forced update added advertisements which disrupt the flow and kill the zen vibe that was the game's main selling point. Now, the fullscreen ads are making the app constantly crash to desktop.

They destroyed their own game in order to bombard it with ads. It's nearly unplayable in its current state.

PS: If you can't even load the game, there is no excuse for giving it a rating higher than the lowest possible. A game that can't even be played should get the lowest possible marks.


Unfortunately, it turns out that the ads for pearls (rewarded ads) are the ones causing most of the crashing. If the game only crashed when the rewarded ads ran, you could avoid the crashing by not playing the ads and missing out on those pearls. However, the crashes seem to be caused by the game contacting the server, so when the server is flaky, the game crashes constantly whether you avoid rewarded ads or not.

LandShark contacted me.
"For Zen Koi, you can get rid of interstitial ads with any purchase in the game, even the cheapest but rewarded ads you can still use it to earn pearls."

He does not deny that the ads are causing the crashes.
He gives no indication that LandShark has any plans to fix it.
His only suggestion - that I give his company money for a constantly crashing app full of ads and IAP - would not solve the problem.
Caveat emptor.

Developer Response ,

We apologize for the experience. We misunderstood and thought that you were talking about the interstitial ads. Regarding rewarded ad crashing the game, we have since informed our ad provider about this issue and they have blocked the ad that is causing the issue. If it is still crashing your game, please let us know which ad in particular e.g. Empires and Puzzles, etc is causing the crash.

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.
