## Description

Binary Fun™: Number System Game is a focused, grid-based puzzle that teaches and tests fast binary conversion skills. Place ones into the zero-filled grid to match decimal, octal, or hexadecimal targets shown at the end of each row and column. With six modes (grids from 3x3 to 10x10) and infinite combinations, the game scales from approachable practice to intense, addictive challenges that reward logic, speed, and mental math.

Ideal for students and anyone wanting to sharpen binary, octal, decimal, and hexadecimal conversion skills, the game emphasizes reasoning over luck. Track best times, compete with friends, and improve conversion speed—useful for computer science learners and puzzle fans alike. Special thanks to Franz Sarmiento for the original development.
