You are right on the theme with surfing graphics in the centre but then skateboarding is referred to as side walk surfing so to a surfer who skateboards it makes sense.

I have 3 playfields and I want to customize one where the wave is turned ino a pool wall as well as modifying most of the plastics to be ramp and pool themed designs because in th US in he 80's they had droughts in California so people drained their pools and they thn become skateboarding heaven.

Worth a game, it is a good player.
