Here is a solution using just an array slice:

use v5.14;
use strict;
use warnings;

my @options = (1 .. 100);

for (1 .. 100)
{
    my $choice = int(rand($#options + 1));
    say 'Choice #', $_, ' is ', $options[$choice];
    @options = @options[ 0 .. ($choice - 1), ($choice + 1) .. $#option
+s ];
}
