Puzzle & Action: Ichidant-R

Puzzle & Action: Ichidant-R (also known as just Ichidant-R (イチダントアール) is a puzzle video game developed and released by Sega in 1994 for the Sega System C. It is the sequel to Puzzle & Action: Tant-R and is the second of the three games in the series. Gameplay is similar to Tant-R: the player must complete a series of mini-games, although its crime theme is replaced with a mediaeval theme. The detectives from the first game return and play the role of knights in a theatre play. The game was ported to the Sega Game Gear in 1994, Mega Drive in 1995, and released on the Sega Ages Rouka ni Ichidant-R compilation for the Sega Saturn. The game was released for the Wii Virtual Console in 2007. All console versions are Japanese exclusives. The third and final game in the series, Puzzle & Action: Treasure Hunt, was released in 1995.

Gameplay
Gameplay remains the same as in Tant-R, consisting of four rounds of a certain number of mini-games, and the game selection rotates so the player must time the selection right for desired game. There are twenty games, many of which follow similar concepts to games in Tant-R: some require the user to press the button at the correct moment, others require the player to memorise and follow a sequence, and some require the player to select the correct option from many incorrect options. Certain games are based on Tant-R games. One such game is where the player, using the hints provided, must select the correct door from a range consisting of various shapes, sizes, and colours. Occasionally, like in Tant-R, a game will become "Lucky!", which plays a random game and grants an extra life, unlike in Tant-R where this option only grants the player a piece, and all must be collected to gain an extra life. At the end of each round there is a bonus stage, but instead of flying an aeroplane like in Tant-R, the player must jump in order to pop balloons. Like in Tant-R, an extra life is granted if a sufficient number are popped. Making mistakes or running out of time costs the player lives.

Like in Tant-R the Mega Drive version includes a "free" mode where players can practise the games. Ichidant-R features a new RPG-style "quest" mode. In this mode, the princess has been kidnapped, and Philosopher's Stones must be collected.
