Teenage Mutant Ninja Turtles Dice Masters: Heroes in a Half Shell is a dice-building game patterned after Quarriors! that features custom dice representing various characters from the cartoon version of the Teenage Mutant Ninja Turtles (TMNT) universe. Unlike other Dice Masters sets, TMNT Dice Masters: Heroes in a Half Shell is sold in as a contained set that gives you all the dice and cards that you need to play.
In the game, each player brings a set of dice to the table; these form the player's team, from which only they can purchase dice. In addition, each player brings two basic action cards, which are placed in the center of the table; both players can purchase them.
During a turn, a player draws and rolls a number of their dice, purchases additional dice, and fields character dice to attack the other player. A player wins once the opposing player has been reduced to zero life.
TMNT Dice Masters: Heroes in a Half Shell is one of several planned Dice Masters games, all of which can be intermixed (or played alone).
