Guide Design https://duo.xiaoxinnote.com/en/updates/game-compatibility-report-2026-10/ https://duo.xiaoxinnote.com/en/updates/game-compatibility-report-2026-10/ Fri, 23 Oct 2026 18:05:00 GMT As of October 24, 2026, the directory lists 214 games — 7 adapted, 2 partially adapted, 205 not checked. But 93.9% ship as universal iPhone/iPad apps with an iPad layout already, so running is one question and verification is another.

Five cuts — region, chart presence, rank, category and dual-storefront apps — then what the data can and cannot support.

Shipping and being genuinely adapted on the Duo is the prerequisite; the rest is a composite judgement — interaction, design, polish, and an idea worth showing.
