Three levels, every hand graded against the exact optimal hold. Score 90 percent or better at any level to earn its certificate, downloadable and shareable. Free, no signup.
Beginner is 20 hands, Intermediate is 50, and Advanced is 100. The pass mark is 90 percent at every level (18/20, 45/50, 90/100). Longer exams leave less room for error and prove more consistency, which is what separates the levels.
What does the certificate prove?
That you can play 9/6 Jacks or Better at or very near optimal. Every hand is graded on whether your hold matches the mathematically best play, computed by an engine validated against all 2,598,960 five-card hands.
Is it graded on luck or on strategy?
Strategy only. You are graded on your hold decision, not on whether the draw hit. A perfect hold that loses still counts as correct.
Is it free and private?
Completely free, no signup. Everything runs in your browser and nothing is uploaded. The certificate is a shareable achievement you generate yourself.
