Puzzle & Action: Tant-R

A puzzle video game developed and published by Sega in 1993 for the Sega System C in Japan. The first installment in the Puzzle & Action trilogy, it is a spin-off of Bonanza Bros.. The characters from Bonanza Bros., Robo and Mobo, are featured as protagonists, functioning as detectives. A prison escapee is chased, and his henchmen interfere. A series of timed mini-games must be completed to defeat the henchmen. The game features references to western culture.

In arcade mode, a dangerous criminal known as 'Boss' has escaped from prison. The Boss has enlisted the help of his henchmen. The detectives (dressed as Sherlock Holmes and Dr. Watson) must chase the Boss and tackle the henchmen. When caught, the Boss and henchmen are arrested. The detectives are then interviewed and are seen on stage in a theatre. In arcade mode, the Boss is chased over locations including a city (featuring landmarks of London and Paris), a desert, a casino, and a construction site. In multiplayer, he is chased along a motorway, and the detectives are congratulated outside the Palace of Westminster afterwards.
