Slide the striker on your line. Then pull back anywhere on the board and let go to shoot. Pull more = more power.
Pocket your own coin = play again.
Striker in a pocket = Foul: you lose your turn and one of your coins comes back to the centre.
Queen π΄: take it after your first coin. Then pocket one of your coins in the same or next shot to cover it. If not, the queen goes back to the centre.
Pocketing the other player's coin helps them.
Pocket all 9 of your coins to win. The queen must be covered first: if your last coin goes in before that, it comes back.
