A video poker trainer that tells you what mistakes cost
Most trainers say “wrong.” This one says “−0.1484 per bet, you played chart line #9 instead of #8” — exact numbers from a full enumeration of every draw, computed in your browser.
How a session works
Deal, pick your holds (keyboard 1–5/Space or tap on mobile), draw. The trainer grades your hold against the exact best play: your EV, the best EV, the difference in coins and dollars, and the strategy-chart line each play corresponds to — so every mistake teaches a rule, not just a feeling. Mistakes are saved (locally, or to your account if you sign in) and can be replayed and drilled until the pattern sticks.
What makes the feedback trustworthy
