Please enclose your code insdie CODE tags.
This:
$secret_word+="$letter"
should be:
secret_word+="$letter"
Unless you are trying to add "$letter" to secret_word each time. In that case you'd need something like:
secret_word="$secret_word$letter"

Be sure to post your game when you finish.

The reason I asked you to post it is that I am nuts about all things 'bash' -so it will be nice to add another bash toy to my collection.
