Lacks something.
Once I got bored enough to want to end the game, I discovered that the odds of throwing down numbers at random was good enough to get me from level 9 to level 19.
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.
(this game is available in English, Spanish, Portuguese, French and Catalan)

Good
But I find it a bit boring. But I won't let my lack of math skills get this blammed so I gave you 4/5.
