Five-pin Bowling is a Canadian variant of duckpin bowling itself a variant of classic ten-pin Bowling. In general, the rules for playing, equipments and shoes are almost identical. The difference is in the scoring. Why five pins? Canadian laziness. Back then, it was easier for the pin monkeys to set frames of five pins than of ten.

The pins have different values for a total of fifteen points, and a bowler has three attempts per frame on a total of 10 frames.

```2       2
3   3
5```
Therefore the frame box will be drawn as follows:
``` _________________
|  |  |  |  |  |  |
|__|__|__|__|__|__|
|        |        | . . .
|        |        |
|________|________|```
As in ten pin, clearing the frame in one bowl is a strike, in two bowls a spare and the next frame's bowl(s) are added to the strike/spare's frame. Clearing a frame in three bowls scores fifteen points but no bonus.

The first bowl of a frame has a special scoring convention (for casual play, just write down the point value):

```O       O
O   O                   HP:  Head Pin, 5 points
.

O       O      O       O
O   .    or    .   O    HS:  Head Split, 8 points
.              .

O       .      .       O
O   .    or    .   O    C/O: Chop-Off, 10 points
.              .

O       O
.   .                   A:   Ace, 11 points
.

O       .      .       O
.   .    or    .   .    L,R: Left or Right, 13 points
.              .```
From then just write the score of the remaining pins knocked down, or strikes/spare. The perfect game is 450 points.
``` 1--+--+--2--+--+--+
|CO|\ |13|R |- |2 |    Frame 1: Chop-Off then a spare (add 13 for frame 2's R score)
+--+--+--+--+--+--+    Frame 2: Right pin standing, miss, then last pin down
