Rhumb Line … 2-player abstract strategy game of observation, placement (nuggets) and accumulation (points).
Players take it in turns placing their nuggets, on the empty board, to form point-winning rhumb lines.
4 in a radius = 10 points … 4 in an arc = 20 points … 4 in a spiral = 30 points.
The twist in the tail is – when players are down to their last nugget, they remove one of their own (once only) but may not place it from whence it came on their next turn … so, look out!
This ‘end-play’ avoids a foregone conclusion, is food for thought and opens up all sorts of scoring possibilities.
