FIND:
PHP Code:
$leaderboard_q = $DB_site->query("SELECT * FROM arcade WHERE game='tetris' ORDER BY score DESC LIMIT 10");
REPLACE WITH:
PHP Code:
$leaderboard_q = $DB_site->query("SELECT * FROM arcade WHERE game='tetris' ORDER BY score DESC LIMIT <number>");
This will need to be done twice, and <number> needs to be replaced with whatever number you want on the highscore.
This however produces produces more queries based on the number you are showing in the leader board (one extra for each person). There was another suggestion in this thread about how to reduce this, but I don't know if it works with the latest verson or not.
Hope this helps?
