Speed Math King: Mental Math

Solve as many arithmetic problems as you can in 60 seconds! Speed Math King is a fast-paced time-attack mental math game where every correct answer builds your combo and sends your score soaring.

⏱️ 60-Second Time Attack
Problems keep coming for a full 60 seconds. Pick the right answer from 4 choices and move straight to the next one.

🎮 4 Game Modes
Choose Mixed (all four operations), Addition & Subtraction, Multiplication & Division, or Times Table (2–9) to practice exactly what you need.

🎯 3 Difficulty Levels
Start with Easy, Normal, or Hard. Division problems always divide evenly, so you'll never get stuck on messy remainders.

🔥 Combo Scoring
Chain correct answers to build combos worth up to 5x your score — but one wrong answer resets the streak!

🏆 High Scores for Every Mode & Difficulty
Each of the 16 mode/difficulty combinations keeps its own high score, so there's always a new personal best to chase.

📊 Results Screen
See your score, correct/wrong count, accuracy, and max combo at a glance, with a special celebration whenever you set a new record.

🌐 Korean & English Support
Switch between Korean and English anytime from the in-app settings.

🔒 No Account, Fully Offline
No sign-up or login required — problems are generated on your device in real time, so you can play without an internet connection. High scores are stored only on your device.
