A richer take on the classic higher-or-lower hunt: four modes, live range logic, optional binary-search coaching, daily streaks, shareable challenge codes and private local stats.
Pick any number inside the live range. You’ll immediately learn whether the hidden number is higher or lower.
Use the highlighted range and guess trail. The optional coach demonstrates midpoint / binary-search strategy.
Try the Daily for streaks, Reverse to test consistency, or Blitz to solve repeated 1–100 hunts in 60 seconds.
