Per my update above this one is less than 1/3 the other and still works if you use use strict; (and warnings)

{ my(@g)=@_; my(@c)=@g; my($t, $s, $m, $p, $f, $h); foreach (@c) { s/[Xx]/10/; s/\//10-$p/e; $p=$_; } while(@g) { $s=shift(@c); $_=shift(@g); /X/ && ($t += $s + $c[0] + $c[1], $f++, $h=0, $f>9?last:next) +; /\// && ( $t += $s + $c[0], $f++, $h=0, $f>9?last:next); $h=$h?($f++,0):1 $t+=$s; $h++; } $t; }

Dropping the my lines will of course stop strict from letting it run and will erase the callers copy of all the arguments to the function. But it is more than 10% smaller...

Update: Failed case 6 of virtualsue's test suite now works correctly.

    Rewriting your code in Golf-ese, just to give you an example, could yield (without really taking into account all the shortcuts) in 166 characters ...
    map{s/X/10/;s#/#10-$p#e;$p=$_}@c=@_;$t=$f=$h=0;while(@_){$s=shift@c;$_ +=shift;/[X\/]/&&($t+=$s+$c[0]+(/X/?$c[1]:0),$h=0,++$f>9?last:next);$f +++,$h=0 if$h;$t+=$s;$h++}$t
    Golf code isn't meant to be pretty or even readable. It's meant to be compact. :)

      Ok last draft, including dragonchild's compressions and optimizations and correcting the case 6 problem which actually saves 3 more bytes.

      map{s/X/10/;s#/#10-$p#e;$p=$_}@c=@_;$t=$f=$h=0;while(@_){$s=shift@c;$_ +=shift;/[X\/]/&&($t+=$s+$c[0]+(/X/?$c[1]:0),$h=0,++$f>9?last:next);$h +=$h?($f++,0):1;$t+=$s}$t

      163 bytes which is basically 1/2 of the previous length.

      Thanks again dragonchild.
