Restore the lost records by pure logic.
A deductive logic puzzle. The guild has reached its 1000th day, but the records of who belonged where are gone, so you rebuild them: 78 adventurers, 20 parties, and the ending each met, worked out from the fragments of guild records alone. No math, no note-taking, just your reasoning and a cute assistant. Like an armchair detective, you fill the grid one cell at a time and lock it, until every assignment is forced with no contradictions. A solo work by the Japanese free-game creator Palsonic, in the lineage of the modern deduction puzzle Return of the Obra Dinn. Japanese only, so the West has barely found it.

01First, the one feeling
- The records hand you fragments, never the answer, so who belonged to which party stays a fog at first, and the only way through is to read the clues against each other.
- But you never guess. One fixed fact forces the next cell true, and that one into the next, so the grid is not a thing you fill in by hunch, it is a chain that logic drives one lock at a time.
- Then the last party falls into position with no contradiction left anywhere, and a chill runs down your spine, the clean click of an answer that could only ever have been this, reasoned out entirely by you.
02Who this is for (and who it is not)
For you
- You love the Return of the Obra Dinn act of filling a table of people and fates from fragments by pure logic, an armchair detective with no hand-holding
- You want a deduction puzzle where every answer is forced, never a lucky guess, with no math or note-taking, just reasoning and a cute assistant
- You want a gem the West has not reached, Overwhelmingly Positive in Japan at 98 percent with only 9 English reviews out of 975, because there is no English version
Not for you
- You do not read Japanese: there is no English version and the store supports Japanese only, so the language itself is the wall
- You want action or fast reflexes, not slow armchair deduction filling a grid at your own pace

Welcome to the Guild Exploration Party! Buried gem
A deductive logic puzzle that asks you to restore a guild's lost records. The guild has reached its 1000th day, and the data on who belonged where is gone, so you reconstruct it: 78 adventurers, 20 parties, and the ending each of them met, worked out from the fragments of guild records alone. No math, no note-taking required, just your reasoning and a cute assistant. Like an armchair detective, you fill in one cell of a grid at a time and lock it down, until every assignment is forced to be true with no contradictions. Made by the Japanese solo creator Palsonic (circle name Parusoni Koubou), who came up through Japan's free-game scene and made the popular freeware Kagami no Majoritia. Overwhelmingly Positive in Japan at 975 reviews and 98 percent, yet the West has barely found it: only 9 English reviews out of 975, under 1 percent. There is no English version, the store supports Japanese only, so the language itself is the wall.
Give it your first passReturn of the Obra Dinn The origin
The origin of the modern deduction puzzle, where you fill a table of people, places, and fates from fragments by pure logic: in 2018, Lucas Pope shipped a first-person mystery where you reconstruct the identity and fate of every crew member of a ghost ship from frozen-moment scenes, with no math and no guessing, each answer locked only when it is forced to be true. This gem is a direct heir to that DNA, the armchair-detective act of cross-referencing clues to fill a grid until every cell is forced, only it pours that pure logic into restoring a guild's lost roster of 78 adventurers across 20 parties.
