On the inner display
Apps built with older SDKs are placed in a phone-sized safe area on a black background. Everything works; you just don't get the bigger screen.
In Split View
iPhone Duo is the first iPhone that can show two apps side by side, and every app takes part — including 三国. Open it on the inner display, then add a second app next to it. You can save the pair and come back to it later.
Duo-specific features
None confirmed yet. Duo-specific features include side toolbars, layouts that react to the fold, and content on the outer display while the app is open inside.

【全新问鼎赛季“乾坤弈境”】 中平之后，黄巾虽平，太平余脉未绝，孙氏亦与之结下旧怨。兴平年间，孙策承父遗志，渡江定吴会，江东霸业初成。当是时，于吉行道江东，以符水济民，远近百姓多归信之。一方执军令以定邦，一方奉太平以聚众，旧怨新争由此并起。南华老仙观太平残法与江东兵势各成气象，知此地旧战未息、劫祸将起，遂将孙策平江东之役与于吉之难皆收入《太平兵卷》，在画卷中演化兵史，寻求破“江东兵劫”之法。 以下为具体更新内容： - 新沙盘 本赛季分为「讨逆军」和「太平军」两个阵营。战斗分为三个阶段，主公可以体验到水战、陆战、以及水陆并进的战斗模式。 「第一阶段：水寨争夺」双方阵营由军港进入水面区域，通过水战争夺鄱阳区域的水寨。 「第二阶段：郡府交锋」双方阵营进入鄱阳区域外围路堤，通过陆战争夺枢要之地鄡阳与葛阳。 「第三阶段：鄱阳决胜」双方阵营进入鄱阳核心区域，以外围建筑为据点，水路并进，争夺核心城池鄱阳。 -新玩法“画中弈境” 在该玩法中，主公将以牌为兵，通过出牌、弃牌和组合牌型积累分数，在出牌次数耗尽前使敌人血量归零。 -新玩法“太平兵卷” 太平兵卷中，提供了多个需部队拥有特定兵种搭配才能生效的特殊战法，特殊战法拥有强力效果，合理搭配战法与阵容，可助主公提升战力。 -新玩法“破局奇策” 提供了内政、军争、战斗三类奇策。合理使用奇策，可助主公在赛季不同阶段，提升发育速度，提高战场能力。 -新武将 群：南华老仙 吴：蒋钦 -新战法 筹策夺锋 久砺成锋
Questions
Does 三国：谋定天下 work on iPhone Duo?
It works, but with black bars. 三国：谋定天下 1.38.0 is built with the iOS 26.5 SDK, so iPhone Duo runs it in a phone-sized window on the inner display.
Does 三国：谋定天下 work on the outer display?
Yes. iPhone Duo's 5.4-inch outer display behaves like a regular iPhone screen, so every iPhone app works there as usual.
Can I use 三国：谋定天下 in Split View on iPhone Duo?
Yes. On iPhone Duo every app can be placed side by side with another app on the inner display — developers don't need to opt in. How comfortable it feels at half width depends on the app's layout.
Why does 三国：谋定天下 have black bars on iPhone Duo?
Apps built with the iOS 26 SDK or earlier run in a phone-sized window on the inner display, and iOS 27 builds can still leave some space empty. The bars disappear once the developer rebuilds the app with the iOS 27.1 SDK — you only need to update the app.
When will 三国：谋定天下 fill iPhone Duo's inner display?
When its developer releases an update built with the iOS 27.1 SDK or later. We read the SDK of every new version of 三国：谋定天下 within about a day of its release and update this page.
What can I do about the black bars until then?
Use 三国：谋定天下 on the outer display, where it works like on any iPhone, or put it in Split View next to another app on the inner display so less of the screen goes unused.
