Number-Spark

Make mental math part of your day.

Math Puzzles turns addition, subtraction, multiplication, and division into quick, repeatable challenges. Pick your pace, choose a theme, and see what you can do.

MAKE IT YOURS
Play with bold Vibrant colors, calm Pleasant greens, or a clean Minimal look that follows your device's Light and Dark Mode. Vibrant is included with free play; Pleasant and Minimal are included with the optional one-time Pro unlock.

A CHALLENGE EVERY DAY
Get a personalized Daily Challenge based on your recent play. Track completed days in your calendar, build your daily streak, and catch up on challenges you missed. Daily progress is personal and stays on your device.

TWO WAYS TO PLAY
Sprint: take on a 10-question run against the clock.
Survival: keep going as the time allowed for each question gets shorter.

FIND YOUR CHALLENGE
Practice all four operations at Warm-up, Focused, or Challenge difficulty. Choose a comfortable starting point or push yourself with tougher numbers.

CHASE YOUR BEST
Earn bonuses for quick answers and consecutive correct answers. Track your best scores for each operation, mode, and difficulty, then review your answers after each run. Three hearts give you room to recover, and mistakes reveal the correct answer.

MADE FOR iPHONE AND iPAD
Play with layouts that adapt to your screen and available window. Use the on-screen keypad or a hardware keyboard, and adjust haptic feedback in Settings.

OPTIONAL GAME CENTER
