Pachinko is sort of a cross between slot machine and pinball. (see http://www.japan-guide.com/e/e2065.html for more detail)
Recently a pachinko manufacturer Sankyo released LOTR-themed pachinko machine: http://www.sankyo-fever.co.jp/new/new_file/lr/top.html
It has a color LCD display, in which various characters from Gandalf to Gollum appear; If you have "Gollum-Gollum-Gollum", you win and so on.
Beware that Pachinkos can be highly addictive (but not for those who can do math), and you may play it all day log and lose all your money. If you start mumbling "My preciouss" while playing, it's too late.
