On jailbroken iPhones running iOS 9-10, you can use tweaks like AppAdmin or DowngradeApp to fetch version 181 directly from Apple’s servers. This is not recommended for daily drivers due to security risks.
Minion Rush downloads additional game assets upon its first launch. Because the original servers for version 1.8.1 are largely offline, the game might get stuck on the loading screen with a "connection error" or "failed to download assets" prompt. If this happens, you may need to look for an "APK + OBB" bundle online, which includes the required data folders to paste directly into your device's Android/obb/ directory.
