About this game

"While looking at the current problem, answer the question that appeared a little while ago."

StackyQ is a short, enjoyable learning and competitive game that combines calculation skills, memory, concentration, and decision-making speed.

Unlike typical math drills, you answer by recalling a question that appeared a little while ago, rather than the current problem displayed on the screen. It requires not only problem-solving skills, but also the ability to remember, switch between information, and make quick decisions.

■ Backward Answering

You can set the shift distance from 0 to 15.

・Shift distance 0: Answer the currently displayed problem

・Shift distance 1 or more: Answer the question that appeared a specified number of times earlier

There is a preparation time at the beginning for the problems to be displayed in order. Formal answering and measurement begin only after all the necessary problems are displayed.

■ Selectable Play Modes

【Normal Challenge】
Practice alone at your own pace. You can set the difficulty level, time limit, question tempo, and shift distance.

【Online PK】
Compete against other players in real time. Supports 2-player and 4-player games, allowing you to monitor your opponent's progress, score, consecutive correct answers, mistakes, and ranking changes during a match.

【AI Training】
Practice against an AI player in a competitive format. The AI ​​is clearly displayed, and practice results against the AI ​​do not affect ranking points.

■ Quick Answers with Handwriting

Integer and decimal answers can be entered directly on the screen by handwriting.

Using a recognition method specialized for numbers and decimals, the system automatically determines the answer after input and proceeds to the next question. Deletion, clear all, and manual confirmation are also supported.

Handwritten line data is processed within the device and not sent to the server.

Problems unsuitable for handwriting input, such as complex fractions, are presented as multiple-choice questions.

■ Included Problem Areas

• Integer and Decimal Calculations
• Distance and Unit Conversions
• Time Calculations
• Percentages
• Fractions Expressed as Finite Decimals
• Fraction Multiple Choice Problems

Difficulty levels can be selected from elementary school, middle school, high school, university, and adult levels.

■ Serious Competition in Short Timeframes

You can choose from playtimes of 30, 45, 60, 90, or 120 seconds per round.

Correct answers earn you base points, plus bonuses based on consecutive correct answers, question difficulty, and answering speed. Incorrect answers result in point deductions, so accuracy is just as important as speed.

Match results, scores, match time, and correct answer judgments are processed fairly on the server.

■ Rankings and Seasons

Supports rankings for the last 24 hours, regional rankings, and world rankings.

Regular ranking points and season points are calculated separately, allowing you to enjoy new competitions each period.

■ Playable Without Login

After setting your nickname, age, and region upon initial setup, you can use basic functions without logging in.

Linking with your OmniAsst account allows you to save and restore account information when changing devices or using multiple devices.

■ Supported Languages

・Japanese
