NumberTris

NumberTris is a puzzle type of game where you have to create lines of numbers that add to a given value. The numbers fall from the top of the screen and pile down at the bottom. You can control the falling number with the keyboard to put it in a place where when combined with its new neighbours they sum a given result. If the screen gets filled with numbers you loose. If you manage to place and clear most of them you will be able to go to the next level.
