Hi there,

An extra layer of security was added to ensure that no bots are used to simulate battles.

Once in a while, you will encounter an anti-bot protection page asking you to enter a 4-digit code from the image.

This is simply to make sure that there is a human playing and, hopefully, it won't be too annoying.

Everything is being done to make this game as secure & fair as possible.

Regards,
dreamer
