The DIGIMON D-TECTOR CARD GAME is an offshoot from the Digimon Collectible Card Game. The cards are compatible with the D-TECTOR digital device, but also allow a typical CCG game.
The D-TECTOR device is apparently quite rare in the USA.
The game allows players to collect and battle with Digimon. There are 4 Card types, Digimon, Digivolve, Digi-modify, and Digi-Destined. There are also 4 sub-types of Digimon, Rookie, Ultimate, Champion, & Mega. The Goal of the game is to defeat the opponent's Digimon, and gain Data Points.
