You have to find sequences of numbers or groups of identical numbers on a 4x4 grid, using digits from 1 to 9. In only two minutes of time.
When you form a sequence, new numbers take the place of the used ones and you gain points.
You can complete series in ascending, descending or casual order (e.g.: 1-2-3-4-5; 5-4-3-2-1; 3-1-4-5-2); or else you can select groups of the same digit: take your pick!
Challenge your friends, even from Facebook: speed and intuition will make a difference!
Numbers is a free app. If you register your profile, you'll get 300 "Nigmi", our virtual currency spendable in both Numbers and Layers - e.g. to bet on the challenges - or within the other apps of La Settimana Enigmistica.
