Silver Stars is hosting a board and card game day and tournament on August 24. The tournaments will be for Munchkin and Citadels.
Location is the Miphal Hapayis building, 88 Derech Yitzchak Rabin, Givatayim (across from the mall). It's a seven hour tournament from 13:00 to 20:00, and there will also be games from 10:00 am on, including World of Warcraft and Twilight Imperium III.
Johnathan Aloni from Silver Stars also pointed me to an Israeli web site that I didn't know: Men in Black, which represents Steve Jackson games in Israel. Silver Stars translates and imports alternative games into Israel.
