Amazon’s Free App of the Day today is for a classic Mahjong app, Frozen Mahjong. This app usually costs Android users $.99. But, today it is FREE! The Frozen Mahjong app features frozen tiles that you must remove to proceed to the next level. In the app, a tile remains free as long it has at least 1 free side (left or right) and if it has no tiles on top. Removing tiles can unfreeze new free tiles. It’s pretty fun and I’m already hopelessly addictive. If you have some downtime this Holiday, why not play a game that sharpens your mind instead of binge viewing “Game of Thrones”? Give Frozen Mahjong a try. Keep in mind, this game will only be free to download today.
