■ Clear Conditions and Game Over

Aside from special situations, each map has a time (turn) limit. If you are unable to reach the goal on the map within the set number of turns, or if a detective dies due to a trap or the like, then you will get a “Game Over.” Instruct the detectives and solve every mysterious within the time limit.

■ Understanding the Map

The map is dotted with areas such as “Mystery Points,” which are mysteries the detectives must solve; “Evidence Squares,” suspicious spots where there is likely evidence; and “Dead Herrings,” which are dangerous traps left by the culprit.

Depending on the detective, they may head for a distant mystery without investigating a nearby one, or they may head towards a trap and die, so intervene in the detectives’ actions to proceed the investigation according to the player’s instructions.

Tantei Bokumetsu

—The Suffering Detective is dying in a trap… Intervene to save her!

Tantei Bokumetsu

■ How the Player Investigates is Up to Them

During “Investigation Simulation Parts,” various conversations between detectives occur as a result of each action. Even the same actions can lead to a different reaction for each detective.

Even when investigating the same case, there are different strategies and information that can be obtained depending on the player, including some conversations only will only occur by meeting special conditions.

■ Map Areas

Mystery Point

Mysteries that detectives must solve. By cutting down each Mystery Point’s set value with the detectives’ “deduction,” they will disappear from the map and you can acquire evidence.

Tantei Bokumetsu

Evidence Square

An area where evidence is hidden. Evidence can be obtained through the detectives’ “investigation.” However, “verification” is required before the obtained evidence can be put to use.

Tantei Bokumetsu

Word Point

Obtain a new “saying” by conducting an “investigation.” The obtained saying can be checked in your “sayings dictionary,” which you can check to learn more about the world of the game.

Tantei Bokumetsu

Dead Herring

Dangerous spots with traps and the like. After every turn ends, any detective on that area will die. Like Mystery Points, Dead Herrings can be removed from the map through “deduction.”

Tantei Bokumetsu

■ Actions


Detectives can move on the map according to their “movement” stat. And rather than being unable to take action after moving, you can also use “Total Movement,” which allows you to move anywhere on the map, regardless of “movement.”

Tantei Bokumetsu

Tantei Bokumetsu


Detectives can cut down the value of Mystery Points and Dead Herrings depending on their “deduction” stat. This can lead to progress in the investigation, as well as save other detectives. However, there are some points that are locked and cannot be “deduced.”

Tantei Bokumetsu

Tantei Bokumetsu


Detectives can “investigate” suspicious spots nearby. The investigation range depends on the “investigation” stat of each detective. Investigating allows you to acquire evidence and sayings within that range.

Tantei Bokumetsu

Detectives can “verify” evidence that has been obtained. The verifiable evidence depends on the detectives “verification” stat. When a “verification” is complete, a new investigation target will appear and the investigation will move forward.

Tantei Bokumetsu

Tantei Bokumetsu


By placing another detective adjacent to a deductive performing a “deduction,” then selecting “cooperate,” a cooperative deduction will occur, allowing you to “deduce” with the cooperative detective’s “cooperation” stat added to the target detective’s “deduction” stat. In this way, even a detective bad at “deduction” can contribute to the investigation.

Start Investigation and Advance Investigation

By selecting “Start Investigation,” every detective on the map will take action simultaneously. However, with “Advance Investigation,” detectives that have that have already been intervened can take action first, allowing you to control the order of the detectives’ actions.
