What do the download and package terms mean?
APK
An Android application package: the single file that installs an app. All 20 apps indexed here are distributed this way rather than through Google Play.
Sideload
Installing an app from a package file instead of an app store. It requires granting an install permission, which should be switched back off afterwards.
Unknown sources
The Android permission that allows a specific app, usually your browser, to install a package. Grant it to one app only and revoke it once the install finishes.
Package name
The internal identifier Android uses to tell apps apart, written like a reversed web address. Two files sharing one are treated as the same app, which is how a copy can replace a genuine install.
versionCode
The whole number a developer raises with each release. Android compares versionCode, not the version name you see on screen, when deciding whether a file is an upgrade or a downgrade.
Minimum Android version
The oldest Android release a build will install on. Across the 20 apps indexed here the values shown are Android 4.4 for two apps, Android 5.0 for seventeen and Android 5.1 for one.
Web app
A version that runs in a browser instead of installing a package. 1 of the 20 apps indexed here is distributed this way and 19 ship an Android package.
What do the signing and safety terms mean?
Signing certificate
The key a developer signs every release with. Android records it at first install and then accepts only updates signed by the same key, which is what gives an app a stable identity.
APK signature verification
The check Android runs before installing, confirming a file has not been altered since it was signed. It proves the file is unchanged; it does not prove the signer can be trusted.
Play Protect
Google's on device scanner for sideloaded packages. It warns on packages it does not recognise, which is normal for this category rather than evidence of malware. No page on this site will ask you to disable it.
Mirror
A copy of an installer hosted somewhere other than the publisher. This site links to none, because mirrors are the main malware route in this category.
Modified build
A repackaged app advertising features the publisher does not ship, such as unlimited credit. Repackaging breaks the original signature, so the file can no longer be traced to its author. Not linked here at all.
Test ID
A shared demo account an operator issues so a new player can look around the lobby. This site publishes no test ID credentials.
Screen recording restriction
A flag an app sets to stop Android capturing its screen, so screenshots and recordings come out black. It is a normal anti-fraud setting, not a sign the app is faulty.
What do the install errors and permissions mean?
Parse error
An install failure meaning Android could not read the file as a valid package. It usually points to a download that was cut short rather than to anything wrong with the app itself.
INSTALL_PARSE_FAILED_NO_CERTIFICATES
A specific parse failure meaning the package carries no valid signature. It appears on files that were repackaged and never properly re-signed, which is why this site links only to publisher builds.
App not installed
The refusal Android shows when a copy of the same package is already present but signed by a different key. Removing the older copy before installing normally clears it.
CPU architecture
The processor type a build was compiled for, usually ARM on phones and x86 on emulators. A package built only for one will refuse to install on the other.
Storage permission
Access to device storage, which these apps request in order to write game assets after installing. Declining it can leave the lobby unable to load its files.
Notification permission
Access to send system notifications, used in this category mostly for promotional pushes. It can be declined at the prompt without affecting the ability to log in and play.
OTA update
An update an app downloads and applies from inside itself rather than through a store. Sideloaded apps rely on it, which means the installed build can change after you first installed it.
What do the account and login terms mean?
Session timeout
The server ending a login that has been idle for a set period. The app usually reports a generic failure rather than naming the cause, which is why reopening it fixes many login problems.
Double login
Signing in to the same account from a second device while the first session is open. Most apps in this category end the earlier session, which can look like being kicked out at random.
Account locked
A temporary block applied after repeated failed sign-in attempts. Waiting out the lockout window and then entering the details carefully once is more reliable than retrying immediately.
Forgot password
The in-app reset flow for credentials you no longer have. It is the only safe route: no legitimate operator asks for your password over WhatsApp or Telegram.
Agent ID
The referral code identifying whoever introduced an account. It decides who is credited for the signup and which support channel handles you, and it does not change the games or the odds.
Activation code
A one-time code or serial some operators issue to confirm a new account or a new device. It is issued by the operator directly and is not something this site publishes.
Emulator login
Signing in through an Android emulator on a desktop rather than a phone. Many apps in this category detect it and refuse the session, and a build compiled only for ARM may not run at all.
VPN and geo restriction
Operators commonly check the country a connection comes from and block or freeze sessions that arrive through a VPN. Using one is a frequent cause of an otherwise correct login failing.
Free credit
Bonus balance an operator adds without a deposit. 2 of the 20 apps compared here are listed as offering it and 18 are not.
