Kegeln

Set the nine pins upright in a diamond formation at the end of the lane.

Roll the ball down the lane, aiming to knock over as many pins as possible in a single roll.

Record the number of pins downed and reset them for the next player's roll.

Take turns in rotation, with each player getting an agreed number of rolls per round.

Add up each player's total pins knocked down across every round played.

The player with the highest total pin count after all rounds wins the game.
