Classical Math Games is a mathematics practice application for children that combines classical mathematical games with Singapore Math curriculum content. The app provides a structured practice environment for families using Singapore Math programs such as Dimensions Math KA, as well as for those seeking classical games that develop mathematical thinking. The interface intentionally avoids points, streaks, leaderboards, and timers, presenting activities that emphasize mathematical structure over reward-based motivation. The app is organized into distinct content areas. Classical Games includes Euclid for all users, with Wythoff's Game and the Tower of Hanoi available through a paid Arena pass. Singapore Foundations covers Number Bonds, Bar Models, Place Value, Fraction Sense, and Extra Practice. Math Facts offers flashcards and Strategy Mode at no cost, while timed drills are included with a paid Arena pass. Geometry and Pattern includes symmetry, pattern continuation, and repeating motif activities. An Early Kindergarten section provides Match & Sort Together for free, with Count & Show, Shape Hunt, Compare & Measure, and Which Has More? accessible with a paid pass. The primary workflow involves selecting an activity area and completing practice exercises at a self-determined pace. Flashcards are available to all families at no charge. A paid Arena pass unlocks the complete activity collection, including future additions at no extra cost, through annual or Full School Pass subscriptions. The app supports short or extended sessions and aligns with the visual language of Singapore Math, including parts and wholes, place value, and fluency strategies.
