## What is Math and Monsters?

Math and Monsters (formerly Castle of Knowledge) is a voice-controlled math adventure. Choose a language and a mode on the animated start screen, listen to a question and answer aloud.

THREE MODES
• Single-digit numbers: practice arithmetic with numbers from 1 to 9. In division, the dividend can be up to 81; the divisor and answer remain 1–9.
• Two-digit numbers: solve more challenging arithmetic problems.
• Terms and definitions: answer questions about addition, subtraction, multiplication and division.

RUSSIAN AND ENGLISH
Choose the language before starting. Questions, hints and speech recognition follow your selection.

PLAY AT YOUR OWN PACE
Pause and resume, restart the selected mode or return to the menu. In the terms mode, tap Repeat question to hear the current question again. Correct answers unlock the next challenge, with animated monsters, sound effects and coins.

PRIVACY
No registration, advertising or analytics. Game content is bundled in the app. Spoken answers use Apple Speech; internet access may be required when on-device recognition is unavailable. Microphone and speech-recognition permission is requested when needed during gameplay.

Addition in single-digit mode (level 1) is free. One non-consumable in-app purchase unlocks the other level 1 operations, all of level 2, and terms and definitions. No subscription. Restore purchases from the start menu. Customers who purchased an earlier paid version retain full access.
