J.J. And Jeff

This is the most exciting case yet for that daring detective duo, J J. and Jeff. They must overcome constant danger from natural and hidden hazards to locate a kidnapped VIP being held by the powerful Boss Kara. To realize their objective, you are put in charge of one character while the other continually shows up throughout the game to offer advice, health, and other special powers. Ported over from the hilarious Japanese card called Ken and Kato (which showed the title characters farting their way through the obstacles), this game is filled with a multitude of worlds that are drawn with exceptional detail. Lots of nasties are always around to offer additional challenge, so you can bet that our heros will need plenty of help if they are to save the day!

Game Reviews

There's nothing complicated about J.J. and Jeff - it's a great looking action game that shares the same type of spirit found in Super Mario Bros. There's a lot more to interact with here, however, and the graphics throughout are pure dynamite! The structure is close to Mario, with four rounds comprising a level. Hidden bonuses are everywhere, as well as rooms where your buddy gives advice and powers you up or let's you play slots for more health, coins, or men. Giant Bosses round out the cast.

People say:


J.J. and Jeff is a terrific game! It's got all the charm of Super Mario, but has slicker graphics and infinitely more challenge. Completing the game is a task that only the most persistant will enjoy, but the game never becomes too difficult. J.J. and Jeff looks, sounds, and plays outstanding!


An adventure game in the Wonder Boy vein. Very well done and unvelievably funny. While tamer than before, there are still plenty of hidden rooms, tricks and items to discover. Graphic/text screens and a lot of action make JJ come off as a game that has never been seen in the U.S. before!


Great running/jumping action in the tradition of Super Mario Bros. The graphics in J.J. and Jeff are cool, with bright colors and terrific animations. The game is difficult, but should prove challenging to players who felt that Super Mario was too easy.


J.J. and Jeff is a great game that will probably not get the recognition that it deserves because it doesn't have a well-known name. Everything that made Super Mario Bros, great is here, along with special graphic screens and mini-games. The game is hard, but there's not much more to dislike.

Enter the crazy world of two of the wackiest detectives of all time--J.J. and Jeff. These bungling private eyes are out to solve a kidnapping case and along the way they'll encounter all kinds of bad guys and obstacles. The duo has to work their way through eight different stages, with 32 playing areas. They constantly search for keys, coins, food items, clues to the mystery, and even hidden screens. Both J.J. and Jeff defend themselves with well-aimed kicks, jumps, and spray cans! It takes a combination of crazy techniques to beat the bad guys, especially Boss Kara at the end of the game. This is one game you'll never forget!

Oh No! the Evil Boss Kara Has Kidnapped Someone, But Not to Worry--Those Two Detectives J.J. and Jeff Are On the Case. Choose Either JJ. Or Jeff to Control Through the Game But Watch Out, Because Your Partner Can Get Jealous, and Then It Becomes Every Man For Himself. Collect Clues and Coins While Searching For Hidden Screens and Keys As You Kick Your Way Through the Eight Levels of This Hilarious Detective Adventure.
