Thanks to some help from
JK, we are pleased to introduce our newest Four In a Row variant:
Double Trouble.
If you enjoy it, send a hurrah to JK. If there are bugs, send me a note.
Update: There was a slight bug in the game when calculating the initial position of the hotspot and the blackhole. Fixing it has affected some of the games in progress. If you feel this has adversely affected your game, let me know and I'll reset the game.
