+### Porting notes for Lua
+
+- This is a straightfoward port with only minor modifications for input
+validation and text formatting.
+
+- The "Try again?" question accepts 'y', 'yes', 'n', 'no' (case insensitive),
+whereas the original BASIC version defaults to no unless 'YES' is typed.
+
+- The "How many rolls?" question presents a more user friendly message
+in case of invalid input.
