Number Series is a logical game with numbers, just perfect for you if you like to challenge your brain. You have to go through 25 levels with varying degree of difficulty and you have only 3 lives to complete the game. What do you have to do? It's simple. In each level a sequence of numbers appears and you must figure out which is the number that follows or what is the wrong number in the sequence. If you do not know the answer you can click on the Show Explanation button and you can see the answer but you will lose one life. To play this game it is necessary to have some Math knowledge as the numbers sequence involves some mathematical operations besides a logical mind. Have fun while training your mind :) ***Permissions Usage*** 1.
