Twelve games as twelve case files
Each game is a numbered case file carrying its venue and its ceiling, so the scale question answers itself: River Wonders and Haw Par Villa and Fort Siloso up to 1,000 pax, the Battlebox at Fort Canning up to 120, the Asian Civilisations Museum up to 150, the Singapore Maritime Gallery up to 200, plus a dining game at selected restaurants for 50.
