Rewrite rules in nginx config

Hi all,
thank’s to accept me in this forum.

I’m a newbie… I have a problem with a rewrite rules that I imported
from
apache

This is my code

index home.php index.php;
location / {
rewrite ^/(.)?$ /categories.php?cat=$1;
rewrite ^/(.
).html?$ /game.php?game=$1;
rewrite ^/(.)/(.).html?$ /game.php?game=$2 break;
}

location /dists/ {
    # Do nothing. nginx will serve files as usual.
}

location /images/ {
    # Do nothing. nginx will serve files as usual.
}
location /admin/ {
    # Do nothing. nginx will serve files as usual.
}
location /css/ {
    # Do nothing. nginx will serve files as usual.
}
location /config/ {
    # Do nothing. nginx will serve files as usual.
}

I’d like ti take parameters from cat and game and use them to know the
path.

This is oc, but so… all others directories don’t work.
Is this configuration so insensitive?
