Terms of use

Last updated 14 November 2026. These terms apply when you play Chan nhau đi at chan.lukepham.uk or use the site lukepham.uk (together, “the game”). Operator: Toàn Phạm, contact support@lukepham.uk. By playing, you agree to these terms. If you don't agree, please don't use the game.

1. The game is free

The game is free, needs no account and sells nothing for real money. It shows Google AdSense ads to cover server costs.

2. Coins, shop items and coin bets

• Coins are virtual items, used only in the game to buy armor, sonar buoys, fuel and the noise-filter sonar, and to bet in 2-player rooms.
• Coins have no monetary value: they can't be bought with real money, can't be exchanged for money, gifts or anything outside the game, and can't be transferred.
• Coin bets are simply a game rule between the two players in a room, using virtual coins. Any deal or wager in real money or real goods based on a match result is prohibited and outside the game's responsibility.
• The operator may adjust item prices, rewards, bet amounts and coin balances to balance the game, including correcting coins obtained through bugs or cheating.

3. Rewarded ads

• You may choose to watch ads for coins, within the daily limit shown in the game.
• Don't use automation, blockers or emulators, call the server directly, or use any other method to claim rewards without actually watching ads. Don't click ads yourself or ask others to click them to generate fake clicks.
• Ads are provided by Google; the game is not responsible for ad content or the sites ads link to. Sometimes no ad is available.

4. Fair play

When playing, you must not:

• Modify game data, tamper with the browser or network, call the server directly, or use bots or tools to cheat, reveal your opponent's ship or gain an unfair advantage.
• Exploit bugs to gain coins, win matches or ruin other players' matches. If you find a bug, please report it by email.
• Attack, overload or attempt unauthorized access to the servers, game rooms or other players' wallets.
• Create wallets in bulk to farm coins.

The operator may remove coins or wallets, or block access for violators without notice.

5. Captain names and conduct in rooms

The name you choose is shown to your opponent and spectators. Don't use names that are vulgar, insulting or hateful, that impersonate someone else, or that contain other people's personal information. Respect your opponent: the trash talk and emotes in the game are just for fun.

6. Progress and service

• Your progress is tied to your browser (see the Privacy policy). If you clear browser data, change devices or lose your wallet key, progress can't be recovered.
• The game is provided “as is”. It may have bugs, be interrupted or under maintenance, change its rules or features, or shut down at any time. A match in progress may be lost when the server updates or the connection drops.
• 2-player rooms are deleted automatically after a period of inactivity; bets in abandoned matches are refunded according to the game rules.

7. Copyright

The source code, graphics, ship models, sounds and game name belong to the operator, except open-source libraries used under their own licenses (for example three.js, MIT license). You may play the game for personal use; sharing screenshots and gameplay videos is welcome. Don't copy or redistribute the game or use its assets commercially without permission.

8. Limitation of liability

To the extent permitted by law, the operator is not liable for damages arising from using or being unable to use the game, including lost progress, lost virtual coins, service interruptions or third-party ad content. Because the game is free and coins have no monetary value, no monetary compensation is provided.

9. Children

The game is not directed at children under 13. Players under 18 should play with the consent of a parent or guardian.

10. Changes and governing law

These terms may be updated; the date at the top of the page changes accordingly. Continuing to play after a change means you accept the new version. These terms are governed by the laws of Vietnam. If the Vietnamese and English versions differ, the Vietnamese version prevails.
