Boxy

Boxy is that really fun game you played with a friend when you were a kid, but in this version you play against the Boxy computer. The game starts with a grid of dots. You and the Boxy computer take turns in selecting and edge of a box to draw. Whoever completes the last edge of a box scores a point and gets another go. The winner is the one with the most completed boxes when all boxes are completed. The game offers different options such as the skill level that the Boxy computer plays with and the size of the grid. There is also a timer that keeps you from stalling. If the timer expires, the Boxy computer will choose a line for you.
