Best "Rook" App Available!
Great take on a classic game. What sets this App apart is the "make your own rules" option called "New Rule Set." It allows you to customize the game to include some of the traditional house rules, such as including the 1s, including the Rook card, setting the Rooks value, etc.
I hope that future updates to "Blackbird" will have more options in the New Rule Set menu (such as the ability to Shoot-The-Moon or calling "low-card" instead of calling trump after taking the nest) to customize the game even further.
