Tap the buttons to place numbers on them so that they sum up to 5. The numbers can sum up to 5 along the  row, column or diagonally.
Numbers get cleared up when they add to 5 so that more numbers can be placed. When none of the rows/columns/diagonals add  to 5 and the 9x9 cells fill up, the game is over. The game supports two modes - infinite and timed mode. Friends can challenge each other for high scores in timed mode.
The buttons need to be just tapped and the numbers need not be dragged to save time!
