** Word Master Stack is the classic crosswords board game you know and love with a twist: You can place letters on top of each other! ** HOW TO PLAY Build words on a gridded gameboard by placing letter tiles next to or on top of the tiles already on the board. All tiles played on a turn must form part of one continuous straight horizontal or vertical line and all new words formed in all directions must be valid. Each letter will score the height of the stack they're on. That means, the higher the stack you form, the more points you get!
