Master the fundamentals of computer science through pure, distraction-free logic. Binary Sum strips away the noise of modern apps to focus on one thing: teaching you how to think in Base-2.
The goal is simple: reach the target number by flipping switches. Each switch represents a "bit" (0 or 1). Flip a switch to add its value to your total. Match the target sum to solve the puzzle and move to the next level.
How it works
Three Modes of Mastery
🟢 Easy Mode
4 bits (Numbers 0–15) – Perfect for beginners to grasp the fundamental concepts.
🟡 Medium Mode
8 bits (Numbers 0–255) – Master the standard byte, an essential standard in computing.
🔴 Hard Mode
16 bits (Numbers 0–65,535) – For the true logic masters. Complete complex calculations.
