Knockabout is a chess-like strategy game, played on a 7 per side hex
board, with dice as playing pieces. The dice normally
determine movement strength, but if movement causes a chain reaction,
the last die in line is re-rolled after the move. The element
of luck is limited; just enough to keep the game interesting, not
enough to dominate the outcome.
The object of the game is to knock your opponent's pieces into the
"gutter" on the outer edge of the board. Dice move
a distance equal to their current value, and induce a chain reaction
(similar to billiard balls) if their path is blocked. In case
of such a chain reaction, the last piece in the chain is
re-rolled. You can read the official rules here.
Dumbot is a credible but not stellar player.
