Numbered

Numbered is a curious game, similar to crossword puzzles, but instead of using letters to form words you have to form mathematical calculations.

In this manner you'll have to test your mathematical abilities, as well as your strategic thinking when it comes to forming the winning combinations.

The board is practically identical to the one in Scrabble, and the longer the combination you make, the more points you'll get. You can even multiply your total by two or three, depending on which cells of the board you use.

You can also put additions and subtractions to your service, and try to put the longest combination on the board to put as much distance as possible between you and your opponents.

You can challenge your Facebook friends or invite them to participate in this addictive game, where you can compete with other random users to reach number one on the world leaderboard.
