## Description

Reach the target number. That's it — that's the game. Getting there is where your brain comes in.

Count Doku hands you a set of numbers and four operations (+, −, ×, ÷). Combine them cleverly to hit the target. It takes seconds to learn, yet every puzzle makes you think — and just five minutes a day keeps your mental math sharp.

THE DAILY CHALLENGE
One puzzle. One day. Everyone plays the same board.
- Solve it to build your streak
- Share your result and challenge friends to beat it
- Come back tomorrow for a fresh puzzle

WHY COUNT DOKU WORKS
Flashcard drills are boring — so nobody sticks with them. Count Doku turns practice into play: instead of memorizing answers, you use numbers creatively to reach a goal. That builds real problem-solving skill and number sense, not just memorization.

TRAIN ALL FOUR OPERATIONS
Addition, subtraction, multiplication, and division. Every puzzle mixes them, so your arithmetic stays balanced and quick.

STUCK? GET A NUDGE
A gentle glow highlights the next two tiles to combine — a hint that points the way without spoiling the solve.

RISING CHALLENGE
Progress through level after level as the difficulty adapts to you. There is always a next puzzle waiting.

DESIGNED TO BE CALM
Clean, minimalist design. Vibrant colors, zero clutter, no pressure — just you and the numbers.
