The ability to sum numbers and perform logical reasoning are the only skills required for solving cryptarithms. Nevertheless, these puzzles are often witty and challenging to solve. A cryptarithm is a mathematical puzzle where digits in an arithmetic equality are replaced by letters. It is defined so that distinct letters correspond to distinct digits. Moreover, when the letters are converted back by the original digits, the resulting equality must be valid. The problem is to find the original digits. 90 сryptarithms with their translations to 6 languages are presented. Enjoy!

Can you follow the pattern? Memory Master is a Simon Says-style brain training game that trains your working memory, attention, reaction time, and cognitive speed — one sequence at a time. Watch the squares light up. Repeat the exact order. The patterns get longer, the colors get trickier, and your brain gets sharper. TWO GAME MODES — TWO WAYS TO TRAIN • Sequence Memory — The classic Simon Says challenge. Watch a sequence of squares light up in order, then tap them back in the same order. Every round adds one more step to push your working memory further. • Value Memory — Remember the color, number, or shape of each square, then recall it when prompted. This mode stretches your short-term memory and visual recall beyond simple pattern matching. FOUR DIFFICULTY LEVELS — FROM BEGINNER TO BRAIN GYMNAST • Easy — Colors only. Perfect warm-up for daily brain training. • Medium — Colors + numbers. Start stacking cognitive load. • Hard — Colors + shapes. Visual memory kicks in. • Expert — Color + number + shape combined. A true mental workout. DESIGNED FOR DAILY BRAIN TRAINING Memory Master isn't just a puzzle game — it's a short, focused cognitive workout you can do in two minutes. Backed by the same principle behind classic brain training apps: regular, progressive challenges improve memory, focus, and mental agility over time. • Personal Best Tracking — See how your pattern recall and reaction time improve session by session. • Daily Reminders & Streaks — Build the habit. Consistency is what actually trains your brain. • Progress Over Time — Watch your cognitive speed, visual memory, and sequence length grow. • Offline Play — No Wi-Fi needed. Train on the subway, in line, anywhere. • No Onboarding Wall — Launch the app and play. No sign-up, no forced tutorial. WHO IT'S FOR • Adults who want to stay mentally sharp — a three-minute brain break that beats scrolling. • Students warming up before exams or study sessions — boost focus, working memory, and recall. • Parents playing with kids — a screen-time game that actually builds cognitive skills. • Seniors keeping the mind active — simple controls, scalable difficulty, no pressure. • Anyone dealing with brain fog, distraction, or just wanting to think faster. WHY MEMORY MASTER Most brain training apps bundle twenty mini-games behind a subscription wall. Memory Master takes the opposite approach: one proven mechanic — Simon Says-style pattern and sequence memory — four levels of depth, and instant access. It's focused, free to start, and designed to actually help you improve. Your brain is like a muscle. Train it. Download Memory Master now and start building a sharper, faster, more focused mind — one pattern at a time.
