After the math OA and coding rounds, Akuna Capital's trader funnel includes a recorded video interview built around a single fast game. Candidates report a 13-row letter matrix (A–M paired with N–Z), a winner row drawn at random, and wagers that are signed pairs of letters — each letter worth its row minus the winner's row. Around 23 timed questions probe the same skill from different angles: computing a P/L when the winner is shown, picking the highest-EV wager under a 20–60 second countdown, re-reading boards that are staggered, holed, disguised as symbols, or mostly hidden — plus memory callbacks that quiz you on earlier boards and even on your own earlier picks, and a finale that asks you to estimate the EV of the answers you just gave.

The simulator above replicates that flow one-for-one with re-randomized boards each run, a per-question timer that auto-submits, and a full answer review at the end. The core insight it drills: a letter's expected value is its row minus the board's mean row, so the best wager is long the deepest letter and short the shallowest — and every board variant is just a disguise over that one rule.
