Produced by Bandai, the Naruto Collectible Card Game was released in Japan in 2003,[168] and in North America in 2006.[169] The game is played between two players using a customized deck of fifty cards from the set, and a game mat. To win, a player must either earn ten "battle rewards" through their actions in the game or cause the other player to exhaust their deck.[170] The cards were released in named sets called "series," in the form of four 50-card pre-constructed box sets.[168][169] Each set includes a starter deck, the game mat, a turn-counter, and one stainless steel "Ninja Blade Coin." Extra cards are available in 10-cardbooster packs, and deck sets. Four box sets sold in retailers are available for each series. Cards for each set are available in collectible tins, containing several booster packs and exclusive promotional cards in a metal box.[171] By October 2006, seventeen series had been released in Japan with 417 unique cards.[168] As of August 2008, ten of these series had been released in North America.[172]
