Santorini is an abstract whose miniimalist components give
it a striking and unique appearance. Starting with a
5x5 grid of squares, players manouver two men each and stack
more squares, in an effort to ascend to a height of 3 above
the base. The base game becomes a little less abstract
with the addition of gods and heroes, who alter the rules in
the rules of the base game.
The official rules are here,
but briefly, you first place your men, then each turn
you move a man, and build a new square adjacent to the man
you moved. You can descend freely, but can only ascend
one level at a time. Adding to a third level above the
base becomes a dome. A man ascending to the third
level wins. If neither of your men can move, you lose.
pretty fierce to me, but lets see what the experts think.
