How it works
Objective
REDUCE OPPONENT to inability to move (or capture majority of seeds).
Rules
Basic rules
SETUP: 4 SEEDS in each pit at start (32 pits × 2 seeds/pit standard, some variants 4)
Signature 2-seeds-per-pit setup (standard).
MOVE: player LIFTS ALL SEEDS from ONE OF OWN 16 PITS + SOWS them COUNTER-CLOCKWISE, 1 seed per pit around own 16 pits (never opponent's)
Signature counter-clockwise own-side sowing.
RELAY-SOWING ('LAPPING'): if last seed lands in an OCCUPIED pit (not empty), LIFT ALL SEEDS from that pit + CONTINUE SOWING; process repeats until last seed lands in EMPTY pit
Signature relay-sowing rule.
CAPTURE: when last seed lands in an EMPTY PIT on OWN side that has 2 OPPOSING ENEMY PITS with SEEDS DIRECTLY OPPOSITE + BEHIND (specific geometry), CAPTURE all seeds from those 2 enemy pits into own store
Signature complex 2-opposite-and-behind capture.
CONTINUES SOWING: even after capture, player MUST CONTINUE lifting if last seed of sowing lands in occupied pit — enables long chains
Signature continue-after-capture.
WIN: opponent cannot make any legal MOVE (no seeds to lift) OR captures most seeds
Signature immobilize-or-most-seeds win.
STRATEGY: very deep + counterintuitive — famous for LONG LAP-SOWINGS that can last 20+ full board circuits before terminating
Signature deep strategic complexity.
Scoring
No point system per se; win by immobilizing opponent (or by capturing majority in some variants).
Win condition · Opponent has no legal move.
