🔎 The dig · Ludus Coriovalli — the worn Roman stone of Heerlen

You are the archaeologist

Nobody wrote down the rules. Build a rule set below, then run the wear simulation to see how well the board it wears down matches the real worn stone. Try to beat your best plausibility!

  • The most-worn lines include a board DIAGONAL.
  • The CENTRE line is comparatively lightly used.
  • MOST of the board surface shows use — pieces travelled widely.

● dark side  ● light side  ╱ a diagonal line  ◯ the centre
