Binary Drop

Binary Drop turns learning binary into a falling-blocks puzzle. Every row is a line of lights worth 1, 2, 4, 8 and up. Lime rows show a number: tap the lights so they add up to it. Violet rows are already lit: add them up and type the number. From level 3 the rows fall like Tetris, and each level adds more lights and more speed. A gentle first level teaches everything by watching, then streaks, rising melodies and confetti keep you going. Learn decimal-to-binary conversion without noticing you are studying.
