About Riddler

Riddler is three math riddles a day, the same for everyone. Each riddle has a trap: an answer that feels right but isn't.

You play from a pixel hot-air balloon. Every answer fires the burner: the closer you are, the bigger the flame and the higher you climb, from Goldfish to Oracle.

Once you land, you see how everyone else did and where your score for the day sits among today's players, as a percentage: top 10% means you beat 90% of them.

Every probability riddle is checked with a million-trial simulation before it goes live.
