A daily prediction puzzle: pick a number, the lowest one nobody else also picks wins.
Lowball is a game of skill, not chance. There is no random draw, no shuffle, no dealer. The outcome depends entirely on what every player decides to pick. The strategy is to anticipate what other people will pick — and find the gap.
The puzzle is sometimes called the Lowest Unique Positive Integer game. Academic game theorists have studied it for decades. It has no closed-form optimal strategy: the right pick depends on how many players you think will play and how they'll reason about each other's reasoning. Picking 1 sounds clever until you realize everyone else also thought of that. So does picking 2. So does picking 7. The fun is in finding the gap that the crowd missed.
Lowball is an independent project, built and maintained by Sam Weber, an independent developer based in New York. The site is hosted on AWS (Amazon Web Services) and was built from scratch in 2026. There is no parent company, no investor, no advertiser tie-in — just a small daily game.

No. Lowball never charges you anything and never pays out cash, gift cards, cryptocurrency, or any monetary equivalent.
Because no money changes hands at any point — nothing to buy in, nothing to cash out — Lowball is not gambling. It's a prediction puzzle with a leaderboard.
