Number Jump is one of the Number Games that you can play on UGameZone.com for free. Our main character wants to reach the sun and there is only one way to do this! Jump on numbers in the proper order and reach the sun! If you jump on a wrong cloud (number), you fall but won't lose, you can jump again on the clouds and you will win the game when you reach the sun. In this game, you will become familiar with numbers' shapes, names and order by seeing and listening to them in their proper order. Enjoy!
