Although the player is supposed to have three balls in each inning, and is allowed to count all he makes on three balls if he gets a strike or a spare, he is not allowed to roll three balls on a break. It was formerly the custom to let him roll the third ball on the chance of getting a break of 10. This was afterward changed to giving him 10 pins, without rolling for them, if he got 9 on two balls; but the present rule is to call it a break if he does not get a strike or a spare in two balls, and not to waste time in rolling the third ball.
Scoring. Instead of putting down the amount made in each inning, the total of the frame is added to the total of the previous score, so that the last figure put down shows the total score up to and including that frame. The following illustration shows the total score of a player for ten innings. The top line of figures gives the number of the frame. The second shows the number of pins knocked down by each ball rolled, and the third line shows how the scores would be actually put down on the blackboard, the strike, spare, and break marks being placed above the figures. With the exception of the second line of figures, which is put in for purposes of illustration only, this might be a copy of an actual score.
| Frames | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| Pins | 8-2 | 5-5 | 10 | 9-0 | 7-2 | 8-2 | 10 | 8-2 | 8-1 | 7-3-9 |
| \ | \ | X | - | - | \ | X | \ | - | \ | |
| Score | 15 | 35 | 54 | 63 | 72 | 92 | 112 | 140 | 149 | 168 |
As the player made a spare on the last frame, he had another ball to roll, on what was practically a new frame, with which he made 9 pins.
Averages. If a team is playing a match, and one of the players is unavoidably absent, it is the custom to give him credit for his average, according to the records of his previous games during the tournament or the season. This is considered better than appointing a substitute to play for him.
There are a great many varieties of Ten Pins, the most interesting of which will be found described in the following Laws of the game, which are reprinted here by the kind permission of the Brunswick-Balke-Collender Co., from their 1908 edition of the “Bowler’s Guide.”
