1.When I get 4th action tile, Should I discard these tiles and get bonus action?
Can I discard these tiles at next round?
2.When I get bonus action because I discard 4 tiles of same color,if there are no earth tokens available, Can I get one earth token from bottom of extra pile?
or Should I do another action ?
Thx for your answer in advance.
1. as Malte said: the bonus action has to follow immediately after your normal action is finished.
2. I'm not sure what you mean by "earth token".
This is how the bonus action works:
- you say "I want to make a land/sun/building action".
- You DO NOT take a action tile!!! You just say what you want to do.
- It doesn't matter if there is no such action tile left!
- you execute you action like any normal action
If you want to make the "land action" and there is no land or bonus token (= hex tile) available anymore, then you cannot choose the "land action". It is not an option to pull a land hex tile from the bottom of any stack of land tokens.
