Most websites claiming to offer "99999 gems" are scams designed to exploit players. Because Dragon City is an online-based game, your resource totals (gems, gold, and food) are stored on Social Point's official servers , not just on your phone. This makes it virtually impossible for a simple "modded APK" or "hack tool" to permanently change your gem count without the server detecting and reverting the change. Risks of Downloading Hack Files
Some sites won't give you a file at all; they will force you through endless "human verification" surveys that generate money for the scammer while giving you nothing in return. Legitimate Ways to Get Free Gems
Downloading unauthorized "hack" files can lead to several serious issues:
Social Point actively monitors for cheating. Using third-party tools is a direct violation of their Fair Play Guidelines and can lead to permanent account bans ranging from 30 to 1,000+ days.
Many "hack" downloads are actually "trojans" or "keyloggers" that can steal your personal information, passwords, and even financial data from your device.
