I think I know how to play the game now. But I don't know how to win the game. If my opponent keeps blocking my way, it would always end up a draw. Is that right?
Well, if you go into your opponent's treasury, the part with the chests, you will have a gem. Then, if you return to your treasury, you can score a point, but watch out! If you have a gem, and your opponent steps on you, you will lose the gem and be sent back to your base!
Also, if you are in your base, the part with your colour on it, your opponent will not be able to step on you. If 30 moves are made without a point being scored, it's a draw.
