What makes Roolz different than bridge (or spades or Rook)?
Roolz is different because it has six suits instead of four and makes use of two trumps instead of one. With sixteen cards per suit and four additional special cards, the 100-card deck is also larger than decks for less-developed bidding games. Perhaps most importantly, Roolz can be played by groups of two, three, four, five, or six people.
