These items can be downloaded from "in game" buy/build mode for "0 Simpoints" :) Please always check the Simpoints!!!
The Casino Column can be found in "Build Mode (F3)" under Columns
The Lucky Sim. Casino Sign and Simoleons in Love Fountain can be found under "Buy Mode (F2)" - Outdoors - Lawn Ornaments.
Try "sort by room" and "sort by "function" and each tab in the category - not only the last tab.
Hope you find them all - I am still looking for the Bar and Barstool.
