do i need a licence to use skins i create myself

@jonathan topf - a commercial license is required if…
• You want to remove the JW watermark
• Your site has ads (Google AdSense, affiliate banners, etc)
• You want to remove the "JW" attribution on the right-click link
• You are a corporation (government & non-profit are free)

You can order a license here:

@abhishek - you cannot play games inside of the player.
