This app is a Question and Answer game (QUIZ) aimed at testing and strengthening your knowledge. You are nominated for the Apapane mission. The mission is to represent the planet Kleper next to the planet Earth. You will be aboard the Castore ship. The computer that controls the generation of energy has been programmed to act according to the results that you will demonstrate during the trip. The goal is to show that you have knowledge about planet Earth. The journey is made up of 7 levels. In level 1 and 2 the questions will be randomly chosen. At level 3, questions are linked to figures that will be displayed. At level 4 and 5 you can choose which subject will be questioned. In level 6 and 7, the letters that form the answer will be mixed with other letters, you will have to select the correct letters. There will be a set time to answer each question, and this time may vary from question to question and from level to level. Question not answered in time will be considered wrong and processed as such. Each level has a minimum number of hits to be obtained. From level 1 to 6 you can get a maximum of 2 points per level, and they are cumulative. For example: Level 1 hit 100%, earned 2 points. You will start level 2, being able to miss 5 questions out of the 15 that will be asked to advance to level 3. If you also get 100% correct in level 2, you will have 2 more points and will start level 3 with 4 accumulated points. And so on. Points will be indicated by the figure of diamonds. At level 7, you will have to get 10 questions right. If you reach level 7 without accumulated points, any error means that the mission failed. If you reach level 7 with 3 points, it means that you can miss 3 questions, but you still have to get a total of 10 questions right. The questions cover: General Knowledge, Geography, Sports, History, Literature, Exact Sciences, Biology, Chemistry, Film and TV, Music, Arts and Paintings, and Tourism. The application allows you to restart the game in general and by level. You have the option to reactivate the wrong questions per level. Questions you get right will no longer be displayed. The app allows all questions to be reactivated. Periodically new questions are made available. Come test and increase your knowledge. Good luck !

Goban3D brings the ancient game of Go — also known as 囲碁 (igo), 바둑 (baduk), or 圍棋 (wéiqí) — to iPhone and iPad. Play on a beautifully rendered 3D goban or switch instantly to a clean 2D board. 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.

The AI is fully on-device • Board sizes 9×9, 13×13, and 19×19 • 26 skill levels: 20 Kyu (complete beginner) through 5 Dan, plus full-strength AI for serious study • Weaker levels use KataGo's Human-style network (trained on human games) so the AI plays like a real person at your rank — not a crippled superhuman • Full-strength mode runs the latest strongest KataGo network published on katagotraining.org as of 15 April 2026 • There's an old Go proverb: "Lose your first 50 games as quickly as possible." 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.
