## What is InfiniteBrainDrill?

It’s like playing a game, even though it’s a study tool! Take on an endless drill that starts at just 30 seconds per round.

A brain teaser and dementia prevention tool that feels like a quiz

Right or left? Solve problems quickly with just two choices in “Infinite Mental Math Drill”! This app is a super-simple 2D math game where you just keep tapping (selecting) the correct answer from the two numbers displayed on the left and right.
“Studying and math drills are boring, and I can't stick with them...” Don't worry if that sounds like you! Just play as if you're solving quizzes in a game-like setting, and your mental math skills and “mental agility” will naturally improve.
　Clear the literally [endless] stream of problems and challenge the limits of your brain!

[Game Features]
・Intuitive two-choice system: Right or left on the screen? Just tap the one you think is correct! There are no complicated controls—you can play quickly with just one hand.
・Endless drills: The problems keep coming until you make a mistake! Challenge yourself to see how high you can push your high score by getting every question right in a row.
・4 Modes for Everyone from Kids to Adults: Covers “Addition,” “Subtraction,” “Multiplication,” and “Division.” Choose a level that suits you, from prep and review for elementary school math to serious brain training for adults.
・Quantify Your Brain’s Growth: Analyze your “mental agility” based on your speed and accuracy. By playing every day, you’ll feel your mental math speed getting faster and faster.
・Completely free and perfect for spare moments: Whether you’re on the train to school or work, or just have a few minutes to spare, you can exercise your brain anytime, anywhere with each round taking just a few seconds.

[Recommended for these people!]
・Those who want to study “math” or “mental arithmetic” in a fun, game-like way
・Elementary and middle school students who struggle with traditional desk-bound studying, or anyone looking for a quick “brain training” or mental workout during spare moments
・Adults who feel they’ve been forgetting things more often or that their minds have become less flexible, seeking “dementia prevention”
・Those looking for a popular, completely free 2-choice quiz game to pass the time
