How strategy works

From the five cards you're dealt, the correct hold is the one with the highest expected value — the average coins it returns over the long run. The biggest payouts here are Royal Flush (800), Straight Flush (50), Four Of A Kind (25), which shape which draws are worth chasing. PerfectPLAY computes the optimal hold and its expected value for every possible hand, so you can learn the exact play rather than a rule of thumb.

You’re reading original analysis. Every hold and expected value here is calculated in-house by PerfectPLAY.vegas for this exact pay table — nothing aggregated, nothing taken from elsewhere. These are never generic charts copied from another site.
