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.

Tap or click a light to turn it on or off. Each column is worth a number shown above it (8, 4, 2, 1). Lime rows: light up the lights so they add up to the number on the right. Violet rows: add up the lit lights and type the total with the on-screen keypad or your keyboard (digits, Backspace, Enter). A solved row disappears. From level 3 rows fall down the board: solve them before they land. A landed row costs one heart; lose all three and the round ends. Clear 40 rows to finish a level and unlock the next one on the level path. Keyboard: number keys to type, P or Esc to pause.
