# GMZBST

> GMZBST is a free online casual-gaming platform. Play HTML5 games in your browser, take trivia quizzes, compete on global leaderboards, enter tournaments and clashes, challenge friends head-to-head, join clans, complete daily missions and earn XP. No download and no payment required.

## Games
- [Games library](https://gmzbst.mobi/games.php): browse and play 70+ free HTML5 games instantly in the browser, with more added regularly.
- Each game has its own page at https://gmzbst.mobi/game.php?slug={slug} (for example ?slug=knife-ninja) with a leaderboard and stats.
- Multiplayer titles (snake battle royale, 8 ball, chess, checkers, drawing) support real-time play and shareable room invites: a friend who scans the invite QR or link lands in the same room, ready to play.
- Games run in a locked-down sandbox: no third-party trackers, ad networks or analytics can run inside any game. This is technically enforced, not just policy.

## Quizzes

- [Clans](https://gmzbst.mobi/clans.php): team up, complete clan missions and climb the clan rankings.

## Frequently asked questions

Q: Is GMZBST really free?
A: Yes. Playing games, quizzes, tournaments and clashes is free. Some partner-branded editions of the platform are subscription services billed by the partner, but gmzbst.mobi itself is free.

Q: Do I need an account?
A: You can try games without one, but an account (free) is needed to save scores, appear on leaderboards, earn XP, join clans and enter tournaments.

Q: What is XP and what is it for?
A: XP is the platform's progress currency. You earn it by playing, winning, keeping streaks and completing quests and missions. It ranks you on leaderboards, and on some partner sites it can be redeemed for real rewards.

Q: How do you stop cheating on leaderboards?
A: Every score submission is cryptographically signed and checked server-side against per-game limits, replay protection and velocity rules. Suspicious submissions are rejected and logged.

Q: Can I play against my friends?
A: Yes. Head-to-head games support live matches and correspondence play, and multiplayer titles have invite links and QR codes that drop a friend straight into your room.

Q: Do the games track me or show third-party ads?
A: No. Games are sandboxed so they cannot contact any third-party service. The platform does not sell personal data.

Q: Can I install GMZBST as an app?
A: Yes. It is an installable progressive web app: use "Add to Home Screen" in your browser. Push notifications are optional.

Q: I run a business. Can I get this on my own domain with my branding?
A: Yes, that is the core of the platform. See https://gmzbst.com or the contact page for the white-label, self-hosted framework and JSON API options.
