sort by alphabet and split into 4 even columns

I have a games list that is constantly growing.

I want to make a list like: http://miniclip.com with all the names of the games in even columns.

Here is the best I got so far: http://www.freeonlinegamefinder.com/footer.php

Any ideas?

 

put the list into an array, sort the array alphabetically (arsort i believe), then output 1/4 of the array elements using something like

$numcolumns=4;
$column=(int) (count($array)/$numcolumns);
for($i=0;$i<$numcolumns;$i++) {
for($x=0;$x<$column;$x++) {
echo $array[$x];
}}

 

how do I output the actual letters though?
Like I want to output "A" before the A games start.

 

$currentletter=substr($array[$x],0,1);
if ($currentletter!==$previousletter) { echo $currentletter; $currentletter=$previousletter; }
