最短3タップでアガリ点数を計算できるシンプルな麻雀用電卓です。 符計算が苦手な方もアガリ形から点数を計算することができます。 2翻70符とか出たときのためにダウンロードしとくといいと思うよ!!!!! ※役一覧がわかって翻数が数えられる人向けです +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- ◆◇特徴 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- ・電卓を模したシンプルなUIで直感的に翻数や基本符を入力 ・最短3タップでスピーディーにアガリ点数を計算 ・基本符の入力は、符計算ができる方向けの直接入力モードと、符計算が苦手な方向けの選択入力モードを切り替え可能 ・もちろん喰いピンやツモ平和、七対子のアガリにも対応(喰い平和30符、ツモ平和20符ルールを採用しています) +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- ◆◇使い方(外部リンク) +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- https://note.mu/barbaroiware/n/n6778b77ee7ea +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- ◆◇よくありそうな質問 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- <基本符選択入力モードで符計算の結果がおかしい!> アガリ形のパターンをすべて正確に入力できているか確認してください。 たとえば暗順子(自力で揃えた順子)と明順子(チーした順子)はどちらも0符ですが、門前形かどうかの判定にも使用していますので、すべて正確に入力して頂く必要があります。 <明順子(or明刻子)を入力したのにロンで門前加符がつく!おかしい!> ロンアガリで完成したメンツ(順子or刻子)は点数計算のルール上、明順子or明刻子と見なされます。 すなわち単騎待ち以外のロンアガリの場合は明順子や明刻子が1つ含まれていても門前となります。 (むしろ明順子や明刻子が含まれていないとおかしい) 非常に勘違いしやすい部分なのでご注意ください。 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- ◆◇免責事項 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- ・本アプリで提供する計算結果等は、正確なデータを提供できるように努めておりますが、正確性、有用性などについて保証をするものではありません。 ・また、本アプリの利用によって利用者等に何らかの損害が発生したとしても、かかる損害について開発者は一切の責任を負いません。 ・本アプリにつきましては予告なしに仕様の変更、改定、更新、または公開の停止をする場合がありますので、予めご了承下さい。

Local matches, private online games with friends via Game Center requested matches, and the world's strongest Go AI, KataGo, all in one app. Whether you've never placed a stone before, want a private match with a friend or club-mate, or are ready to test your skills against the strongest Go engine on the planet — Goban3D is for you.

Start on 9×9 at 20 Kyu — after 2 or 3 games, winning comes easier than you might think. Each time you win, raise the skill by 1 or 2.

ACCESSIBILITY — GO FOR EVERYONE Goban3D makes Go genuinely accessible — across ability, skill level, device, region, and language. No other Go app on the App Store declares any accessibility features. Goban3D has 100% coverage across all seven Apple categories: VoiceOver with full board-position labels, Voice Control, Dynamic Type, Reduce Motion, Reduce Transparency, Sufficient Contrast, and Differentiate Without Color. The app starts in 2D by default, and the 2D SwiftUI board is where the full accessibility stack lives — including complete VoiceOver board navigation. When VoiceOver is on, the 3D toggle is disabled to keep the accessible experience front and centre. A dedicated high-contrast mode and adjustable grid-line thickness help players with low vision. DEVICES • Also runs on Mac and visionOS via "Designed for iPad" • Minimap on smaller iPhones ensures every intersection meets Apple's 44pt minimum tap target, even on 19×19 Free to play, with gameplay that is always ad-free. A brief ad appears on launch and just before scoring mode, so your time on the board is never interrupted. Remove all ads with an optional yearly subscription.
