Christmas Avalanche is a match-3 game with a holiday theme in which you must click on groups of three or more items of the same type to make them disappear from the board. The more items you destroy in the available time, the more score you will get. You will also find bombs of different colors on the board. Click on them to eliminate items more easily. There are also bonuses scattered around, which can be used by making matches with them. If you combine multiple bonuses, you can score lots of points. The items will move rapidly from left to right, so you must act quickly because if the items reach the other edge of the board, the game is over.
Unfortunately, the game only includes one mode and only one difficulty level. Moreover, graphics and sounds are really simple and there is no music. You can start the game from level 1, 4 or 7, but you cannot save games.
In short, I really wouldn't recommend Christmas Avalanche because there are much better games with similar gameplay and absolutely better graphics.
