Welcome to Star Nim, a variant of the classic combinatorial game 'Nim'. A player's action each turn is simply removing a token from the board
by selecting it and then clicking it.
The objective of this game is to be the last person to remove a token.
It is often the case that tokens are 'connected' to each other by a line.
When such a connection exists, you have the option of removing both tokens instead of just one.
If there are two such connections, you will have to choose between the two.
Then, click either of the selected tokens once more to remove both:
If there is only one token connected to the selected one (i.e. one connected token has already been removed), the choice is now just between removing itself or removing both.
Again – once selected – either token can be clicked to remove both.
If there are none connected to the selected token,
you can remove it as per usual, but only that token.
Play continues in this way until there are no tokens left on the board.
As previously mentioned, the first person to remove all of the tokens wins. It is not necessary that only one token can be removed to win.
Enjoy!
