Terminal "tenpin" bowling game built with TTY toolkit components.

Bowling known as "ten pins" is a game played by rolling a heavy ball down a narrow lane and attempting to knock down ten pins arranged in a triangle. A player can bowl up to two times per "frame", and a game consists of ten frames. A special rule applies to the last frame in which you can roll up to three times if you have a strike or a spare.

If a player knocks down all ten pins in the first throw, then they have what is called a "strike", and no second ball is rolled in the frame. When some or none pins are knocked down in the first throw, then a second ball is awarded. If all pins are knocked down in the second roll, then the player gets a "spare".

The maximum number of points possible is 300 which a player can get by rolling 12 strikes in a row.
