I was playing Happy World and when i entered the machine it took me to: 

• happyworld.zone/HappyZone/?p=true (port 80)
• http://happyworld.zone/HappyZone/?p=true%20(port%2080)

the two are to the same place, i think

And the link to when you jump from that place after you win Happy Zone took me to:
