Nginx都重写和重定向？

Question

I have arcade gaming web site. I want to convert my urls to sef.

category : domain.com/index.php?category=mario-games > domain.com/category/mario-games
game details : domain.com/index.php?game=mario-game > domain.com/mario-game.html
featured : domain.com/featured.php > domain.com/featured
pages : domain.com/page.php?id=contact > domain.com/page/contact

After searched Internet, I sucsessfully achieve rewrite rules. But my old urls still accessible. How can I both redirect and rewrite old urls to new ones ?

server {
    listen       80;
    server_name  domain.com;
    return       301 http://www.domain.com$request_uri;
}

server {
    listen       80;
    server_name  www.domain.com;
    root   /usr/share/nginx/domain;

    index  index.php index.html index.htm;

    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;


        location / {
        rewrite ^/(.*).html$ /index.php?game=$1 last;
        }
        location /category {
        rewrite ^/(.+)/$ /$1 permanent;
        rewrite ^/category/(.*)$ /index.php?category=$1 last;
        }
        location /page {
        rewrite ^/(.+)/$ /$1 permanent;
        rewrite ^/page/(.*)$ /page.php?id=$1 last;
        }
        location /featured {
            rewrite ^/(.+)/$ /$1 permanent;
            rewrite ^/(.*) /featured.php last;
        }






    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
    }

    location ~ \.php$ {

        include        fastcgi_params;
    }
