While version 1.5.6 was a major update, the game has since moved to version 1.6 and beyond on most platforms. Unofficial downloads are often outdated and buggy. Official and Safe Ways to Get the Game
If you are looking for the best experience, it is highly recommended to use official platforms where the game is frequently available at a low cost (often around $5–$15 depending on the platform and sales).
Unofficial .apk or .exe files from third-party sites frequently contain hidden malware or "cleaner" apps that steal personal data.
Many sites promising "free codes" require you to complete tasks or surveys, which are often social engineering scams designed to harvest your information without ever providing a working game.
