# How to prevent cheating in online games

> Developers stop cheating with server-side checks, anti-cheat software and reports; players help by reporting, guarding accounts and avoiding cheat tools.

Online cheating is prevented on two levels. Developers make the server, not the player's device, decide what is possible, then add anti-cheat software, statistical checks and fast bans. Players help by reporting cheaters, protecting their accounts and never installing cheat tools, which often carry malware.

## What developers do

- **Server-authoritative design.** The server checks movement, damage and inventory, so a hacked client can't simply claim a kill or teleport.
- **Send less information.** If the client doesn't receive enemy positions behind walls, a wallhack has nothing to show.
- **Anti-cheat software.** Tools such as Valve Anti-Cheat, Easy Anti-Cheat, BattlEye and Riot Vanguard look for known cheats, tampered files and suspicious access to game memory.
- **Behavior analysis.** Servers flag impossible reaction times, accuracy or speed, and machine-learning systems compare players with normal patterns.
- **Ban waves and hardware bans.** Delaying bans keeps cheat makers guessing; banning hardware identifiers or phone numbers makes new accounts harder to create.
- **Ranked access rules.** Requiring a level, two-factor authentication or a verified phone for ranked play raises the cost of cheating.
- **Reports and replays.** Player reports and review systems catch cheaters automation misses.

## What players can do

1. Report cheaters through the in-game report tool.
2. Don't buy boosting services or play on accounts boosted by others.
3. Turn on two-factor authentication so cheaters can't steal and use your account.
4. Never download "free hacks." They often contain password stealers.
5. Play on official servers or community servers with active moderation.

## Why people cheat

Most cheaters want to win without practice, climb ranks faster, show off or sell boosted accounts. Some just enjoy ruining matches. That's why anti-cheat is an ongoing arms race rather than a one-time fix.

## FAQ

**How do online games detect cheating?**
By scanning for cheat software, checking game files and comparing your statistics and inputs with what a human could plausibly do.

**Is cheating in online games illegal?**
In most countries it breaks the game's terms of service rather than the law, so the penalty is a ban. Some countries, such as South Korea, have laws against making or distributing cheat programs, and developers have sued cheat sellers.

**How common is cheating?**
It depends heavily on the game: popular free-to-play shooters attract the most cheaters, and estimates vary widely.

**What should I do if a cheater ruins my match?**
Report them, leave the party if they're a teammate, and avoid queuing with them again.

**Does Cheat Engine work on multiplayer games?**
Using it in online games can trigger anti-cheat detection and bans; server-side checks also make most online values impossible to change.
