How good are you at solving mathematical problems? Math Lines is a free online Zuma game that allows you to see how good you can be at doing math. The rules of the game are a bit twisted, since you are used to making sets of three or more objects that are similar in order to remove them; in this game, the sets have to add up to 10, and can be made of a little as two balls. This means that shooting a number 7, where there is a number 3, will have them removed, and you win some points. However; you can get more pints by shooting a number 6 where there is a number 3 and number 1, next to each other. The total still comes to 10, but you will have removed three balls. Earning you more points, you also need to know that at times, the shooter shoots two balls, and this could throw a spanner in the works. You just have to adjust accordingly and proceed with the game. The speed at which the balls travel is not so fast, so you have more time to do the math in your head. This is a very basic game in terms of features, perhaps due to the fact that you have to be on your toes doing math in your head and not looking for special features to enhance your chances at winning. For those who love mathematics, this will be an easy game, but it is also a great game for those who would like to sharpen their ability to solve arithmetic problems; this is simply getting balls that have a total of 10, but being able to do so at speed and accuracy will enhance the ability to solve mathematical problems, so go ahead and give the game a shot.
