Rattlebones is a game about building dice. You start with standard six-sided dice, and throughout the course of the game you can remove sides and replace them with other sides that let you do all sorts of wonderful things. Every time you score points, you get closer to finding Rattlebones and, er, winning the game. Yes, winning! It's an experience to six-sided-die for!
In this game, each player fields one of the superhero teams, with each hero — Captain America, Wolverine, Spider-Man, and more — being represented by custom-tooled dice; each team must be composed of 15 dice, and a player can "purchase" dice only from his team. Each hero also has one or more character reference cards, which show the special abilities for the characters based on the die rolls. Different versions of these cards will be available in booster packs, allowing for more customization of your team. Players use these dice to collect energy, recruit new heroes, and battle head-to-head. In addition, each player brings two basic action cards to the game, which are placed in the center of the table; both players can purchase these cards. A player wins once the opposing player has been reduced to zero life.
The Marvel Dice Masters: Avengers vs. X-Men Starter Set comes with 44 custom dice, 38 cards, two dice bags, and a core rulebook. Booster packs include two dice with two matching character cards.
This "Dice Masters" system already has one other title announced — Yu-Gi-Oh! Dice Masters, due out Q1 2014 — and each of these games works the same way and a team from one set can be played against any other Dice Master team. The Marvel Dice Masters: Avengers vs. X-Men Starter Set retails for $15, while each Booster Pack costs $1.
