When looking to download Fishdom mods, beware of fakes: Any mod, generator, online tool or hack that offer you free gems, coins, god mode (unlimited lives) is 100% fake and will never work, since this is an online game and these values are stored on the Playrix servers. To find working cheats, use this tool.
If you are at any point unable to find and acquire working downloads, then your only way to cheat in Fishdom is to follow tutorials and try to hack the game manually using game hacking tools for either Android or iOS. Game hacking tools will allow you to mod the game memory on your mobile device, which is to say it modifies the current state of the game on your phone.
