+    Game played on an orthogonal depiction of a standard 9x9 Emergo board.
+
+p
+  | Nothing disappears in this game: captured pieces become part of the
+  | capturing unit. Therefore, a piece or unit will always be understood
+  | as a combination of W white (elementary) pieces and B (elementary) black
+  | ones, with
+  br
+  | W >= 0, B >= 0 and W + B >= 1.
+
+p
+  | The 9x9 board is initially empty.
+  | Each player receives 12 stackable pieces, "in hand".
+  | At each turn, a player must pick an action among the followings:
+  ul
+    li Enter a new piece (W + B = 1) on the board.
+    li Move a unit along diagonals, by one square.
+    li Capture something.
+
+h3 Entering moves
+
+p.
+  Introducing a piece such that the opponent can take it on next turn is
+  forbidden, unless another capture is already available.
+
+p At first move, white cannot place a piece at the central point.
+
+p.
+  If the opponent already placed all his pieces in hand, then a
+  "shadow piece" enters, formed by all the remaining units available
+  (thus in this case W + B > 1).
+
+p.
+  While you have pieces in hand, none of your pieces can move on the board
+  unless they capture something.
+
+h3 Captures
+
+p.
+  Captures work exactly as in Checkers: by jumping over a diagonally adjacent
+  piece to land on a free square just behind.
+  If a capture is possible, then it must be played; in this case no piece can
+  be introduced on the board.
+  If after a capture another is possible with the same piece, it must also be
+  played — except if that implies turning at 180 degrees.

+    Before and after black captures, jumping at the marked location.
+    The next white piece must be captured too.
+
+p.
+  Captures can be described formally as follows.
+  If, as white, W1/B1 jumps over W2/B2 at square S2 to land on S1', then
+  W1/(B1+1) arrives on S1' while W2/(B2-1) stays on S2.
+  If W2 = B2 - 1 = 0, nothing remains at the captured unit location.
+  As black: exchange W and B.
+
+p.
+  In other words, each unit is a stack of friendly and enemy pieces, with
+  friendly pieces on top. After each capture, the prisoners part of the
+  stack is incremented, while the jailers quantity at the captured
+  location decreases by one.
+
+p.
+  When several capturing chains are available,
+  the player must select one of the longest (as in Checkers):

+    From https://www.mindsports.nl/:
+    White's only option is to capture clockwise.
+
+p.
+  A piece can be jumped over several times, as long as it contains
+  at least one enemy unit (controling it).
