Periodically, several times a year, before the start of the new season, stores hold a sale of goods to fill the shelves with new collections. In addition, there are Black Fridays and various promotions that are held individually by different stores. In the Sale Mahjong game, you will also fall into a total sale and be able to buy everything from a button to a TV at a bargain price. And you don't even have to spend money to do it. It is enough to find pairs of tiles with the same product and remove them from the field. On the right you will see a timeline, try to empty the field before it becomes empty in Sale Mahjong.
