What it is
Stroum JCC American Mahjong is a Mercer Island, Washington (Seattle metro) civic drop-in for American Mahjong at the Stroum Jewish Community Center. It is not Japanese Riichi. The J’s series page frames Monday evening drop-in play, beginner classes at other times, plus occasional daytime drop-in, Mahjong Masters free play, and an annual tournament. Evening open play is not an instructional class.
Who it’s for
Players in the Seattle / Mercer Island area who want an NMJL-card table. The dated event pages say all skill levels are welcome, member or guest, but that this is casual play — not a lesson. Bring your own current (2026) National Mah Jongg League card; the J provides sets.
Why it’s listed
This is a first-party JCC series with dated 2026 event pages, not a scraped directory card. As of 2026-08-23 it is the clearest American Mah Jongg civic calendar in the Seattle metro.

- Dated Mahjong Mondays pages: 6:00–8:30 pm drop-in. Sets provided; bring a standard 2026 card. Everyone welcome, member or guest. Not an instructional class.
- A separate Daytime Drop-In Mahjong page for 2026-08-24 (1:30–3:30 pm) says Monday afternoons June through August, registration free, advanced registration requested. Do not advertise daytime play past August unless a new dated page appears.
