What is radx.io?

  • radx.io the codable math game® is a number coding game system designed to build fluency with patterns, operations, and number base conversions using tangible game pieces.
  • We've developed our featured game, called Ada!, to generate a fast-paced decimal to binary conversion challenge. Speed solving against opponents has you thinking fast and efficiently to be the first to solve the code sequence.
  • To keep it simple, we opted to present one game to get you started, but you can imagine that with just on-off bits, you can develop an almost infinite number of game variants.
  • We've tested the game at family game nights, high school computer science classrooms, and many one-on-one sessions, which all helped tighten and hone gameplay mechanics.
