Using this site or activating an account means you accept these terms. If you do not, please do not use the site.
You must be 18 or over to train here or hold an account.
Every ground is free to train on. There is nothing to buy, no subscription, and no payment step at any point. If anything asks you to pay and claims to be us, it is not us.
Training credits and any other on-site currency exist only inside this service. They:
The grounds are practice environments. No real money is involved and there is nothing to win.
Strategies you write stay yours. By putting a bot on the public ladder you agree we can show its name and score. We may run your strategy on our infrastructure for the purpose of scoring it, and nothing else.
Do not use a strategy to attack our infrastructure, mine anything, or run work unrelated to the ground you submitted it to. We cap run length and cancel jobs that try.
You are responsible for the address you register and for what happens on your account. We may suspend an account used to abuse the service, disrupt the ladder or exploit a bug.
If you ticked the box at signup we may email you about new grounds. Every message has an unsubscribe link that works immediately, with no need to contact us.
The site is provided as it is. We do not promise it runs without interruption, and runs can be lost during maintenance.
So far as the law allows, we are not liable for loss or damage arising from your use of this site.
We sometimes link to other sites. We do not control them and are not responsible for what is on them.
These terms can change. The date at the top shows the current version.
