Presale Reservations Start for the Latest Blockchain Game: CONTRACT SERVANT – Now in Development in Japan

AXEL MARK INC. is glad to announce the opening of its official English website for the new blockchain game CONTRACT SERVANT -CARD GAME-, as well as the start of token presale reservation sales.

CONTRACT SERVANT -CARD GAME- is a trading card game for PC and Mobile, made using blockchain technology. Players collect cards with beautiful designs known as Servants, edit decks (teams), and face off with other players.

We plan to hold an advance presales for a limited time and limited number of Servants before the service launches. Presale reservations are available from the website PlayDApp ( Those who make reservation will receive an email notification when presales begin.

In addition to buying and selling Servants on the Market using Ethereum, players can also Mix Servants they own to create new ones. All Servants are designed to have different stats, unlike the multiple duplicates that traditional card games issued. This makes similar decks a rarity among players. In order to triumph in Battles with other players, you will need both the wits to find true value in Servants on the Market and your own unique deck-building strategy.
