Sugoku is a drill app for high school mathematics, shown the way it looks in a printed textbook: fractions stacked with a horizontal bar, √ with a vinculum, raised exponents, and ∫, Σ, lim rendered properly. Problems are generated on the fly, so you never run out of practice. WHAT YOU CAN PRACTICE - 235 topics covering the full Japanese high school curriculum (Math I, A, II, B, C, III): algebra and proof, quadratic functions, sets and logic, trigonometry, exponentials and logarithms, analytic geometry, differentiation and integration, sequences, statistical inference, vectors, complex plane, conic sections, limits and calculus. - Three difficulty levels, from fundamentals to university entrance exam level. - Answers are not forced to be integers: type fractions and radicals directly. The answer boxes show the shape of the answer, so you learn how results are written. - Figures label vertices, angles and side ratios; graphs plot key points (intercepts, vertex, center). - Missed problems come back immediately. Bookmarks and mistake analysis let you drill only your weak spots. KYOKUISEN (RANKING) - A daily rating match with a leaderboard grouped by school year. - One attempt per day; watch a video ad to add attempts, up to three per day. - Your nickname and rating are visible to other players. Do not enter your real name or anything you would not want public. - Offline, your own records are shown instead. SUGOKU PREMIUM (IN-APP PURCHASE) - Removes ads. - Three Kyokuisen attempts every day, no video ads needed. - 20 coins at the start of each Kyokuisen season. - Bookmarks up to 500 items (20 on the free tier). - Answer timer with time analysis, plus the Sakura skin. - One-time purchase.
