Numberama – the classic time killer

So you’ve got a few minutes or an hour to kill. Sure you can play Angry Birds, but that’s getting annoying after a while. If you need a simple game (suitable to any age from 7 to 107) Numberama is a perfect game.

Some of you may have played this when there was no iPad or iPhone with a piece of paper and a pencil. If not, this is the time to learn it.

Rules are simple. You need to cross out neighbouring digits to empty the screen. The digits can either be the same, or they can total 10. If you make a mistake or you change your mind you can always go back up to 20 steps. Here’s a short video explaing the gameplay.
