❓ How to Install Games with APK and RPA Files?

Some Android games come with both an .apk file and one or more .rpa files. Here’s how to install them correctly:

Install the APK file
- Tap on the .apk file and follow the prompts to install the game on your Android device.
- Make sure “Install from unknown sources” is enabled in your device settings.
Place the RPA file(s)
- After installing the APK, don’t launch the game yet.
- Use a file manager app and go to:
  Android > data > [game folder] > files > game
- If the game folder doesn’t exist, create it manually.
- Copy or move all .rpa files into this game folder.
Launch the game
- Now open the game. The extra content (like images, sounds, mods, etc.) from the RPA files will be loaded.

⚠️ Notes:

If the game crashes or doesn’t open, double-check that the .rpa files are placed in the correct folder.
Do not unzip .rpa files — they should remain exactly as downloaded.
For best results, use a reliable file manager like ZArchiver or Solid Explorer.

❓ Why does my Android show a security warning when installing the game?

When you install a game downloaded from outside the Google Play Store, Android may display a security warning. This is a standard system alert for “unknown sources” and doesn’t necessarily mean the file is harmful.

Our team does its best to gather and share games from trusted and well-known sources. However, since these games are created and distributed by independent developers, We are not responsible for the content or behavior of the game itself. Use your discretion and only install games from developers or sources you feel comfortable with.

❓ What Are Modded Games?

Modded games are modified versions of the original games that offer extra features, unlocked content, or changes not present in the official release. These modifications are usually made by independent developers or fans and are designed to enhance gameplay or remove limitations.

⚠️ Please Note:

Modded games are not created by the original developers.
Some mods may not work on all devices or may crash unexpectedly.
Always use caution and install modded games from trusted sources.

❓ What is a "Walkthrough/Cheat/Unlock/Multi... Mod"?

Walkthrough Mod:
A Walkthrough Mod adds helpful tips, highlights, or guides inside the game to show the best choices, routes, or scenes. It helps players get the best results without guessing.

Cheat Mod:
A Cheat Mod enables features like unlimited money, points, or energy. It lets you skip grinding and enjoy the full game faster — but it may reduce the challenge.

Multi Mod:
A Multi Mod combines multiple mods (e.g. walkthrough + cheats + gallery unlocker + Custom Settings …) into one package.

Unlock Mod:
An Unlock Mod gives you access to features that are locked in the original game, such as premium scenes, full galleries, or choices that are normally restricted.

❓ What is an "Incest Patch"?

An Incest Patch restores or enables family-related content that was removed or censored in the public version of the game due to platform rules.

⚠️ Always check local laws and age restrictions before using such patches
