Japan-O-Rama Slot Review

The Japan-O-Rama game can be found at casinos using Rival software. Rival as a software provider offer a high quality game product but have gained a substantially negative reputation amongst players due to the high level of player issues many of the casinos using their software have generated. As such real caution is advised if choosing a Rival casino to play with. Rival software does publish the Return to Player (RTP)/House Edge figures for all of their slots games in the game help files. The house edge of Japan-O-Rama is 6.29%.


The Japan-O-Rama game has 5 reels, 20 payline and you can bet up to 10 coins on each of the paylines.

The ‘Godzilla’ symbol is wild, only appears on reels 1, 2 and 3 and expands to cover any reel it lands on.

There are two bonus features when playing Japan-O-Rama. The first bonus feature is activated when you receive 3 or more of the ‘Geisha’ scatter symbol anywhere on the reels. When that happens you’ll be awarded between 5 and 20 complimentary spins depending on the number of Geisha symbol you receive. During the complimentary spins all wins are multiplied by 3.

The second bonus feature is activated when you receive 3 or more of the ‘Sumo’ scatter symbol anywhere on the reels. When you receive this you will be taken to a new screen showing a Pachinko game. The balls will award prizes as they fall.


A house edge that could dwarf Godzilla and a game that’s nothing special.
