Place nine, then slide
Take turns placing nine counters each on the board’s 24 points. After all placements, move a counter along a connecting line into a neighbouring empty point. With exactly three counters left, you may fly one to any empty point instead of sliding.
Make a line of three
Completing a marked three-point line makes a mill and lets you remove one opposing counter. Remove a counter outside a mill if any exist; if all opposing counters are in mills, choose one of those. Completing two mills at once still gives one removal.
Win or draw
After placement, win when the opponent has fewer than three counters or cannot move. Three repetitions of the full position and turn draw. The game also draws after 50 completed movement turns without capture. Placements do not use that count; a capture resets it.
