Castle of Knowledge
Math adventure
$0.99 · Designed for iPad. Not verified for macOS.
A voice-driven adventure in Russian and English: solve problems out loud, defeat monsters, and clear the castle. Tour two quizzes you on math terms!
"Castle of Knowledge" is a voice-controlled math game for kids, built around the 3rd grade math curriculum. No keyboard: listen to the question and answer out loud — the game checks your answer and opens the way forward.
TOUR ONE — MENTAL MATH
15 riddles covering addition, subtraction, multiplication and division. Difficulty rises as you go, from simple problems to three-digit numbers. Every correct answer triggers a burst of energy, and the monster in the room disappears.
TOUR TWO — MATH VOCABULARY
An advanced mode with no numbers at all: "What is the result of addition called?", "What is a dividend?" — questions about addends, sum, minuend, subtrahend, difference, multiplier, product, dividend, divisor and quotient.
TWO LANGUAGES
The game starts automatically in Russian when your device language is Russian, or in English otherwise. Questions, hints and speech recognition use that language. There is no language-selection screen.
HOW IT WORKS
• The game reads the question out loud
• The child answers by voice — a digit or a word
• Speech recognition (Apple Speech) forgives small mispronunciations
• A correct answer triggers a dramatic monster defeat and moves you to the next room
WHO IT'S FOR
Built for 3rd grade students practicing mental math and times tables, and anyone reinforcing math vocabulary from the school curriculum — answers are spoken, with no keyboard required. Pause/Resume and Start over buttons let you control the session.
PRIVACY
The game shows no ads, requires no registration, and collects no analytics data. The microphone is used only to recognize spoken answers during play.
