Guesstimathon is the fast-paced multiplayer trivia game where strategy meets estimation.
Inspired by real consulting, PM, and quant interview questions, Guesstimathon challenges you to guess real-world numbers — and bet on your confidence.
“How many Subway sandwiches are sold each year?”
“How many iPhones were sold last quarter?”
“How many golf balls can fit in a school bus?”
Make your guess. Bet your coins.
Then watch in real time as you and your opponent find out who got closer — and who takes home the pot.
Whether you're:
Practicing for a case or quant interview
Competing with friends in strategic battles
Sharpening your market intuition
