Numberama is the good old puzzle and probably the best time killer, that was played on copybooks in universities and colleges at the 90's.
The objective is to cross out neighbouring (vertically or continiously) pairs of digits to completely empty the screen. You can cross out the same numbers or the ones that give a total of 10.
