What listeners say

A curated, balanced selection of Apple Podcasts reviews.

Just a wonderfully produced pod about finding edges, AP play, +EV decisions. Even more entertaining are the stories that come from finding out how people create those edges and the situations they lead to.

Cannot recommend this podcast highly enough. If you’re into gambling, math theory, and the intersection between being a nerd and beating the house for millions of dollars, this podcast is for you. The guests are varied and extremely interesting with different angles and stories to keep it fresh. The host, John Reeder, is an incredible producer and interviewer - he keeps the discussion flowing freely and edits the shows with surgical precision. Subscribe and check out all the episodes, but I recommend starting with David and Goliath, parts 1-2.

But master mc sickeningly · Jul 2023

No matter how long an episode is I always want more. Clearly a labor of love and his passion for the subject shines through. Highly recommend.

DavidHill · Feb 2023

Every show is a terrific listen of great stories and offers up a different way of thinking about gambling and risk taking. Always anticipating the next episode. Keep ‘em coming.
