Check out QuadraDots on the AppStore:
QuadraDots is a simple and addictive adaptation of the classic pencil and paper game. The objective is simple: connect dots and close boxes!
Players take turns connecting dots to form the edges of boxes, and earn points by completing the final edge of a box. Play alone against the computer on one of three difficulty settings, or compete against a friend on the same device. If you?re looking to learn new strategies, you can even watch your device play against itself!
QuadraDots also features three exciting game modes:
Classic Mode ? This is the mode you?re used to. Score a point for each box you close, and attempt to score more points than your opponent
Normal Mode ? This mode has a twist! Certain boxes are worth more points than others, so strategize to get higher scores.
Epic Mode ? The boxes in this mode can have special effects, as well as penalties. Every move in this game can swing the balance of a game!
Each of these modes and difficulties is available on different sizes of game board, ensuring that no two games are ever the same.
Have fun!
