Why why why didn't I set up a RRGSP! (Registered Retired Gamer Saving Plan)
So many games.... so little time...
I think the game comes with too few magnets. What usually happens is that as soon as someone has to take back some magnets, they other person usually wins. So it makes for a very short game.
What we have done to make the game more "interesting" is we have purchased another 9 polished magnetite stones (odd/weird shapes are best) usually found in natural jewelry/stone/gem/crystal shops.
The extra 3 stones allow for 4 more stones each when one on one and 9 stones each when playing with 3 people. This way the person who is forced to pick up stones doesn't lose right away, there is a very good chance that someone else will pick up stones the next time.
