About Christmas Triple Mahjong GameChristmas Triple Mahjong is a timed 10-stage Mahjong Solitaire game where you must match 3 identical open stones at a time to remove them from the stack. A stone is considered open if at least one side (left or right) is open and if no stone is on top of it. Open stones have a cream background color while stones that are not open have a darker background color. For a stone to be considered identical it must have the exact same item type and quantity displayed on it. The exceptions to the prior rule are that flower stones can be matched with any other flower stones & season stones can be matched with any other season stone. Selected stones show a green outline until they are matched off or until you select another stone type. Earn 100 points for each set of stones matched off and 30 points for each second you have when you complete a stage. If you get stuck there are buttons for taking hints and shuffling the stack in the lower right corner, though using them costs you points.
