I have played this game for years. With computer, with online players, with my friends and most of all with my family. Its been really an amazing game. It's best part is that even after being too simple, that any person from any age group can understand the rules very well, it is very challenging at the same time.
Despite of the good points of this game, it also has some points which need some improvment. Most of the times it is seen that the game is not fair. It appears that it always has some soft corner for the losing player as it tends to make him win and make the other player to wait and wait because he does not get the number he needs to enter the center.
However, I would suggest all of you to download it and give it a try as it can be proved as great family time.
