The Tartarus Key

Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.

Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.

Too few observations to say whether a discount moves this store's chart at all: across the last 30 days Nintendo · best_sellers · United States has just 8 day-to-day chart moves that followed a price cut, against 2,629 that did not. We are publishing the count instead of a direction — 20 is the fewest we will draw a conclusion from, and price collection outside the United States began on 6 August 2026.

Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
