Cryptarithmetic vs Hack the Code

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.

Hack the Code is a logic and deduction game where you need to crack your opponent’s secret code before they crack yours. Set a code made of digits, make guesses, and get hints: how many symbols are guessed correctly and in the right place, and how many are guessed but in the wrong place. Every move brings you closer to the solution. PLAY THE WAY YOU LIKE • Single-player — practice against a random code and sharpen your strategy • Two-player over Wi‑Fi — two phones on the same network, no internet or registration required • Two-player on one device — pass the phone to your opponent after entering the code and after each move • Match series — the score carries over between rounds, so you can play all evening CUSTOMIZE THE MATCH TO YOUR LIKING • Code length from 3 to 6 symbols • With or without repeats — you decide how hard the puzzle will be • Two win modes: “Decisive move” (with a chance of a draw) or “First to guess” • Three types of hints: counter, symbol highlighting, or locking in correct positions • Attempt history — show everything, only the last attempt, only hints for it, or hide completely • Personal history in two-player mode — each player sees only their own moves; opponents can’t peek at each other’s attempts WHO THIS GAME IS FOR Hack the Code will appeal to those who love board-style logic games, puzzles, and short battles of wits. One match takes a couple of minutes; a series can last all evening. Play at home around one table, over Wi‑Fi with a friend in the next room, or solo when you want to train your logic.
