'Block It Classic' is an entertaining and addictive classic puzzle/board game for iPhone that you may have played in school on notebooks. It is so much fun playing at school with friends. The iPhone version is even better. This game will keep you entertained for hours. Play it with your friends and family or VS the iPhone. This is a two player game (vs Human or iPhone). Both players (namely red and black) TAP on ONE DOTTED LINE each turn to mark a side of block. A player can own a block by marking the 4th side when other 3 sides have been already marked. As only one side can be marked in one turn, it becomes so much fun trying to get the other player to mark 3rd side of a block for you so you can complete the block by marking 4th side on your turn. When a player completes the block, s/he gets a bonus turn. As the game nears end, it becomes so much more interesting and difficult. The iPhone version of this game is the best way to play this game.
