This game has a ball, a putter, slopes, water, bridges, bunkers, tunnels, walls and a lucky wheel, not to mention a hole for each of the 18 levels.

If you can complete the whole course in 10 under par or better (the lucky wheel score is added to your stroke count), you will be shown the secret "Unlock Level Select" code. Please don't tell it to anybody.
