# Learn maths by playing. A card game where every move is a calculation. SummaGrande turns arithmetic practice into a competitive card game. Play cards, build equations, and outscore your opponents — no worksheets, no drilling. WHAT'S INSIDE - Fast card matches for 2 players, online or on the same network - Difficulty that adapts to what you actually need to practise - Classroom mode with a supervisor view, letting a teacher run a whole group at once - School league play — track results across matches and seasons - Cross-platform: play against friends on Windows, macOS, Linux, iOS, or Android EARLY ACCESS SummaGrande is playable and complete enough to enjoy today, but it is still growing. We are adding game modes, classroom tools, and content throughout Early Access, and player feedback directly shapes what we build next.
