Natural numbers are better for your health, so try Number Series :)

Number Series is a logical game with numbers, just perfect for you if you like to challenge your brain.

You have to go through 20 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.

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. When you end the game or lose all your lives you can introduce your name and save the level you reached in the high score list.

To play this game it is necessary to have some Math knowledge as the numbers sequence involves some mathematical operations besides a logical mind.

The Pro version doesn't have ads and the Show Explanation is fully active. Also there is a new feature. Now you can see the discovered clues right from the app.

Have fun while training your mind :)
