StackyQ

StackyQ is a fast-paced brain game that combines calculation, memory, focus, and competitive timing. Its core mechanic is simple but challenging: while viewing the current question, you answer a question that appeared earlier. By adjusting the offset distance, you can answer the current question or recall one shown several steps before. The larger the offset, the more memory, concentration, and quick judgment are required. Each match can last 30, 45, 60, 90, or 120 seconds, making StackyQ suitable for both quick daily practice and intense competitive sessions. 【Main Modes】 ■ Solo Challenge Customize the difficulty, match duration, question pace, and offset distance, then train at your own speed. ■ Online Battles Compete in 2-player or 4-player matches. During a battle, you can follow your opponents’ progress, scores, combos, mistakes, lead changes, and comeback status in real time. ■ AI Training Practice the battle flow against clearly identified AI players. AI training matches do not affect ranking points. 【Handwriting Input】 Answers containing integers, decimals, and supported mathematical symbols can be written directly on the screen. Handwriting is recognized on the device. After a brief pause, the answer is automatically submitted, while delete, clear, and manual confirmation controls are also available. Original handwriting stroke data is not uploaded to the server. Questions that are not suitable for handwriting, such as complex fractions, are presented in multiple-choice format. 【Question Types】 • Integer and decimal mental arithmetic • Distance and unit conversion • Time calculations • Percentages • Fractions with finite decimal forms • Multiple-choice questions involving complex fractions Difficulty levels range from elementary school to middle school, high school, university, and adult levels. 【Real-Time Competition】 Correct answers earn base points, combo bonuses, difficulty multipliers, and reasonable speed rewards. Incorrect answers reduce your score. Players in the same match receive questions in the same order, while each player can progress at their own pace. Final answers, match time, scores, and results are determined by the server. 【Rankings and Seasons】 StackyQ includes rankings for the last 24 hours, regional rankings, and global rankings. Regular ranking points and seasonal points are calculated separately. Seasonal rankings reset at the end of each season, while past results remain available as part of your history. 【Accounts and Data】 To begin, simply set a nickname, age, and region. The main features can be used without signing in. By linking an OmniAsst account, you can save and restore your account data when changing devices or using multiple devices. 【Languages】 StackyQ supports English, Japanese, and Chinese. View the current question, remember the previous one, and challenge your calculation speed, memory, and focus. 【Terms of Use & Privacy】 Terms of Use (EULA): https://stackyq.com/terms/ Privacy Policy: https://stackyq.com/privacy/
