How it works
• A hex value (up to 64-bit) is shown. Pick the memory size it equals.
• Sizes are binary: 1 KB = 1024 B, 1 MB = 1024 KB, and so on.
• Handy anchors:
• Correct answers score points — longer streaks earn bonuses.
• Every 5 correct, the level rises: bigger units (MB → GB → TB).
• A wrong pick costs a life. 3 lives, then game over.
• After each answer the breakdown is shown to reinforce the conversion.
Controls
• Click / tap an option, or press 1–4.
• Space starts the game.
Goal — build fluency reading hex values as real memory sizes.
