When it is your turn to throw, press a key to start the round.
You will hear a tone that raises and lowers in pitch.
This tone is the strength bar, the higher the tone the harder you throw the horseshoe.
You don't want to throw it at max strength, because the you will throw the horseshoe too far.
After you have pressed a key to select your strength, you will get another bar, this one a tone that moves from left to right.
This tone is the direction indicator. You will want to throw the shoe when the tone is equal in both speakers, dead center.
Press a key to throw the horse shoe and if you did everything right, you will get a ringer. A ringer is worth 3 points.
If you did everything almost perfect, you will get 1 point. If you completely miss, you get no points.
To play with 2 players, launch the program with the number 2 as the only argument. Without the 2, you will play verses the CPU.
2014-05-04 19:18:28 -04:00
Launch the program with the letter c as the only argument to watch a computer verses computer match.
To play expert mode, launch the program with the letter e as the only argument.
the first person to 15 points wins the game.
