Kaguya Table: The Expansion

Kaguya Table: The Expansion is a 2010 Touhou fan idle whose entire premise is a joke executed with mechanical sincerity: Kaguya Houraisan, the sealed princess of the moon from Imperishable Night, flips a table. Repeatedly. Endlessly. The table takes damage, the table grants XP, and somewhere around the billionth point you realise the gag has a real progression system underneath it, with stat allocation, doubling costs and a rebirth finish line.

What the loop feels like

You flip the table, the table grants XP, and levels arrive in a steady drip. Each level hands you three stat points to allocate across six stats with names that are already the joke: Tactics, Rage, Neetery, Bossiness, Impatience and Hardcoreness, each bending the flip loop in its own way. Neetery, famously, makes the next flip free. That's Kaguya Table: The Expansion.

Then the long game surfaces: the first Mastery level costs one billion XP, and every level after doubles the price, so the run becomes a slow argument between your stat build and an exponentially receding goal, one hundred Mastery levels standing between you and the promised Rebirth. Progress auto-saves, the table keeps flipping, and you keep allocating. That's Kaguya Table: The Expansion.

The systems doing the work

The documented systems are simple and honest: an idle XP engine that accrues from the flip loop, a six-stat allocation layer spending three points per level, and the Mastery ladder whose doubling cost curve converts a comedy premise into a genuine endgame commitment. It is fan work in the truest sense: the author is unrecorded, the game circulated as a Flash file in Touhou community spaces around 2010, and its satire of its own subject, a princess who has been idle for centuries, being a natural fit for the idle genre, doubles as the design document.

Where it stumbles

Honest gaps first: no AI Mode passes ran, no independent criticism exists, and the original Flash host is gone, so this entry is built from community documentation and preservation records. The design stumbles are structural: a single-loop game with no visual feedback beyond the flip, stat choices whose effects are largely invisible without community notes, and an endgame that is doubling costs all the way down. It is a joke with a spreadsheet inside, and the spreadsheet eventually wins.

Playing it today

The original web version is defunct, but the game survives in Flashpoint Archive, added in the 10.1 release, which is the only verified way to play it. In the wider catalog it sits with other single-gag web originals like Progress Quest, which proved a decade earlier that a character doing one thing forever could carry an entire game.

The verdict

A fan-made genre joke with real mechanics underneath: proof that idle design and Touhou shitposting were always compatible, and a table that has now been flipped for longer than most studios keep a live service running.
