There are not many rules for the game itself (chat and forum are covered in separate topics). Almost everything that a player can on do on the game filed is allowed (kill or play peacefully, steal a ball or give it to another player, etc.).
However, some things are forbidden:
1. Spawning characters for the purpose of getting them easily killed multiple times to give a player an unfairly high number of kills. It doesn't matter whether you are "helping" your other account or another person.
Every round is logged and such cases are clearly visible. All stats gained by cheating will be removed.
We have already removed 371 rounds from 9 users.
If you try to do it, you'll make your stats only worse.
2. Spawning multiple characters in one round to disrupt the normal game process in any other way.
3. Creating a large number of accounts. Unless you try to cheat or troll, 1-2 accounts are more than enough to play and have fun.
4. Exploiting any other loopholes or bugs in the game that give a player an unfairly high scores, free items, gold or plutonium. In particular, by creating multiple accounts.
3074 unfairly gained plutonium has been already removed from cheaters' accounts.
5. Unauthorized use of bots. We know that writing bots is fun and we respect it. We are not against bots, we are against interfering with the fair game statistics. If you want to create a bot, contact admins. We will give an account a special "bot" status, which means killing it will count as killing our own bots. Then you can officially test it as much as you like.
6. Pursuing a particular player through different rooms or servers to hunt or bother him/her after that player changes a room or a server to not be in one room with you.
7. Purposefully impeding normal operation of the game and this site in any other way.
Breaking these rules may result in loosing stats and getting temporarily banned from the game.
