Scoring marks — the shorthand of a scoresheet
Single characters that record what happened to one delivery or one frame. They are grouped because each pair inside them means something similar and scores differently: a dot and a W both mean no runs, but only one is a wicket; a cross and a slash both mean the frame was cleared, but the cross carries two deliveries of bonus and the slash one.

Wicket mark (W)
A capital W in the scorebook, recording a dismissal.
Strike mark (X)
A cross on the scoresheet, recording all ten pins down with the first ball.
Spare mark (/)
A forward slash on the scoresheet, recording ten pins down in two balls.
