Eight Bam’s 2026 Card by the Numbers series now includes Sim vs Play: a side-by-side look at how often each hand can reach mahjong in a 10 million game simulation, versus how often it actually wins in the Daily Challenge.
The simulation evaluates every hand on the card concurrently, so the rankings reflect tile and rule probabilities — not player favorites or bot strategy. The Challenge column uses more than 100,000 winning hands from the 2026 season.
One early takeaway
Players may be overlooking some strong multi-suit Runs hands. The simulation ranks them highly because they can pivot across numbers and suits — but tracking those options takes more thought at the table.
What you’ll see
- Hands — all 72 lines on the card, with Probability and Challenge bars
- Sections — the same comparison rolled up by card section
- Sort by Hand/Section, Probability, or Challenge to explore the gaps
