Data Leak

Data Leak is a game of making words and breaking passwords. Acting as a skilled computer hacker, you will attempt to break your opponents’ passwords before they can break yours, knowing that these passwords must be formed from a pool of only 45 letters.
Unfortunately, data leaks happen every turn and you’ll have to be canny about which letters of your password you reveal to your opponents.
By browsing the darknet and using threats such as viruses, worms and trojan horses, more letters will be revealed until you eventually break your opponents’ passwords.
The last player with an unguessed password will win the game.
