It's been about a year since I've played it, but from what I recall the more you rev the throttle, the higher Fonz rides up the screen..the road twists and there are other motorcyclists to avoid, which is harder when Fonz is close to the top but that's how you score higher points. The points can reach a maximum even with time remaining, which was a bummer, but another friend thinks he can mod the score counter so it conitinue until the timer truly runs out which would make the game a great party competition game. The graphics are BW. The handle bars shake violently if you hit an obstacle. As for sound, it has an 8 track player with the orig tape. I think it's music rather than game effects but not certain. The same modder bud thinks we can install an mp3 player in it for random rock n roll music to enhance the coolness factor as if the Fonz really needed any extra...Aaaaaaaayyyy!
