joshi tm: That's a good idea. We don't have a hyperspace on BrainKing yet.

BuilderQ: Because only one line can disappear after a move, not two.

SLAYER: What about a variant where one placed piece randomly disappears each fifth move? :-D

No, even in this case the rules are the same as for Spider Line4. All squares between target position and the corresponding wall must be filled.

Then I should add it. Thanks for notifying me.

Isn't it mentioned in rules? When only one column remains, a piece can be placed on top of opponent's last piece.

Just the outside wall would disappear and everything else shifts that way. If you fill two walls at once [corner move], both lines disappear and everything shifts diagonally.

Hey Line4 experts,
what would you say to Spider Linetris? Would it be an interesting variant? :-)

It would be very easy to implement on BK. Does anybody know more about that variant?

Done, see the rules.

Kevin: Thanks for the tip. I will think it over.

I'll be glad to play another game with you :-)
