What happened when the price fell
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.

Reviews, worldwide (the counter carries no country): 1.29/day in the week to Aug 29 → 1.29/day in the week after.
Too few observations to say whether a discount moves this store's chart at all: across the last 30 days Google Play · Top Paid · United States has just 7 day-to-day chart moves that followed a price cut, against 1,963 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.
