How to install

Download the zip file
Click the Windows button above to download MiceForce.zip. If your browser asks whether to keep the file, choose to keep it.
Extract the contents
Right-click MiceForce.zip, extract it using WinZip or 7-Zip, and pick a location (like your Desktop).

Important: inside you'll find MiceForce.exe and the instructions text file. Make sure to extract everything together.
Launch the game
Open the extracted folder and double-click MiceForce.exe to start playing instantly.
If Windows warns you
The first time, you may see "Windows protected your PC." This is normal for unsigned programs. Click More info, then Run anyway. It only happens once.
Create your account and play
Click "Create account," pick a username of 3 to 11 characters, set a password and email, solve the captcha, and you're in.

Download the zip
Use the macOS button above to download MiceForce-mac.zip. Safari usually unzips it automatically after downloading.
Extract the app
If it wasn't extracted automatically, double-click the zip. You'll get MiceForce.app. You can move it to your Applications folder or leave it on your Desktop.
Allow the app to run (one-time step)
Right-click MiceForce.app → Open → click Open again on the warning that appears. macOS blocks unsigned apps by default; this only happens once.

Don't see an Open button? Go to System Settings → Privacy & Security, scroll down, and click Open Anyway next to the MiceForce warning.
Launch the game
From now on, just double-click MiceForce.app. It runs on the real Flash Player, so everything works like on Windows.

Mac with Apple chip (M1 or newer)? The first time, macOS may ask you to install Rosetta. Accept it; the game needs it to run.
Create your account and play
Click "Create account," pick a username of 3 to 11 characters, set a password and email, solve the captcha, and you're in.

Install Flatpak
Flatpak is required to install and run MiceForce. If it isn't installed yet, follow the installation instructions for your Linux distribution's wiki.
Download the game
Click the Linux button above to download MiceForce.flatpak.
Install MiceForce
Open a terminal in the folder containing the downloaded file and run:

flatpak install --user MiceForce.flatpak

First-time setup: Flatpak may download and install additional dependencies required to run MiceForce. This is normal.
Launch the game
Once the installation is complete, launch MiceForce from your desktop application menu.
Create your account and play
Click "Create account," pick a username of 3 to 11 characters, set a password and email, solve the captcha, and you're in.

Troubleshooting

Mac: "app is damaged and can't be opened"

This can happen if macOS re-quarantines the app after it's moved around. Open Terminal, type xattr -cr (with a trailing space), drag MiceForce.app into the Terminal window to paste its path, then press Enter.

The game loads but won't connect

Check your internet connection. If it still fails, the server may be temporarily down — try again later.

My antivirus blocks the file

This is a common false positive with unsigned executables. Add the file to your antivirus exceptions.
