Rules below stolen from freegame at viewtopic.php?f=38&t=1010
"Quick rule overview:
1 hidden move
1 open scan costing 2 pt
3 base stones each worth 5pt (will lose 5pt when one gets captures)
plus zones are 5pt when played ( bonus will not be lost when stone gets captures. points are only awarded once for each zone)
minus zones are -5 points (points only deducted once)
each stone on the board is 1 pt (will lose the point when it gets captured)
when we have put a base stone on the same coordinate it gets removed and it turns into a minus zone.
after we each posted our hidden base they are revealed and we make a komi bet.
the rest is like normal go with area scoring."
