What are the basic rules of board game Tock?

It seems you're asking about a board game called "Tock." However, there's no widely known board game with that name. Could you please clarify?

Perhaps you're thinking of a different name, or you're referring to a game that's less popular or homemade.

If you can provide more details like:

* Any other names the game might be called

* A description of the game's theme or gameplay

* Where you encountered the game (e.g., a website, store, friend's house)

I can help you find the rules!
