## What is Cryptarithmetic?

Cryptarithms — crack the code of numbers

What if the digits in mathematical equations were replaced with letters? Your task is to figure out which digit is hidden behind each letter. Sounds simple? Give it a try.

How it works

You are given an equation like “COT + COT = DOMA”. Each letter represents a unique digit from 0 to 9. Find all the matches so that the math works out. One letter — one digit. No randomness, just logic.

Five game modes

Classic — solve at your own pace with no time limits
Timed — race against the clock for adrenaline lovers
Zen — no scores or rankings, just pure enjoyment of the process
Daily puzzle — one unique challenge every 24 hours
Tournament — five puzzles in a row, total score, a true test

Four difficulty levels

From simple two-digit equations for beginners to multi-layered challenges with 10 unique variables for true mathematical detectives.

Progression system

Earn points and experience for every solution. Rise from Beginner to Immortal through 10 mastery levels. Unlock 25 achievements — from your first solution to marathon win streaks.

Hints without pressure

Stuck? Spend points on a hint — one letter will be revealed. In Zen mode, hints are always free. Don’t want to spend points — watch a short ad.

Thoughtful details

— Dark and light themes that follow system settings
— Daily reminders (customizable)
— Detailed statistics: best streaks, average time, breakdown by difficulty
— Supports addition, subtraction, and multiplication
— Endless generation of unique puzzles

Cryptarithms have existed since the early 20th century and remain one of the most elegant forms of mathematical puzzles. Now in your pocket.
Train your mind. Every day.
