Goal. Move all 15 of your checkers around the board and bear them off before your opponent.
Roll. Each turn, roll two dice. Move one checker per die. Doubles give you four moves of that value.
Blocking. A point with 2+ of your checkers is yours — opponents can't land there.
Hit. Landing on a point with exactly 1 opponent checker sends it to the BAR. It must re-enter on your home board before moving anywhere else.
Bear off. Once all 15 of your checkers are in your home board (the last 6 points), roll dice to bear them off. Exact rolls land on points; larger rolls can bear off from the farthest occupied point.
