Unsolved Case Files Game Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Unsolved Case Files is the best-performing unsolved case files game brand in July 2026, moving 2,500 units across 3 ASINs for 33.3% of Top 10 volume. Cryptic Killers follows with 1,800 units (24.0%), ahead of Thames & Kosmos on 800 units (10.7%).

With 7 brands splitting the Top 10 and 68.0% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $15.00 to $21.32, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B08P16S3ZM booked 600 units at $17.99, with ▲ 20.0% MoM change. On the growth side, B0DTLLTSBS leads positive momentum with ▲ 200.0% MoM growth on 300 units, with B0FXSWT6RJ close behind at ▲ 200.0% MoM on 300 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
