Curio is a free browser game for two people. One of you creates a room and texts the link — the other joins instantly. No download, no sign-up. You answer prompts, guess each other's picks, and chat in the same private room. Rounds start light and get deeper as you go. Perfect for couples, friends, or long-distance pairs on a video call. Works on phone and desktop. Pick Stranger (9 rounds) or Duo (12 rounds) and play in under a minute.
