Voracious

This is a math addition and subtraction puzzle game. The interface displays addition/subtraction equations with question marks, and number options lie at the bottom. Players mentally calculate the unknowns (sum, addend, minuend, etc.) and tap the correct answer - right choices earn points and advance progress, training basic arithmetic skills. The core experience: By randomly placing the question mark (as addend, minuend, subtrahend, or sum), the game forces flexible use of addition/subtraction formulas, avoiding rote memorization. It’s a math enlightenment game blending fun and educational value.
