About that name

Four Jacks.
One very big problem.

Stack four untapped Jacks into an 8/8 Superjack with Trample. Excess damage beyond what’s needed to kill its blockers hits the defending player. It’s the play the game is named for.

years around the table

A game made by people who love games

Seven years to find the balance.
The rest spent playing.

Superjack started with a question: could the kind of strategy we loved in our favorite games fit inside an ordinary deck of cards?

It took more than seven years of building, breaking, and balancing to find the answer. We took out the 8s, 9s, and 10s. The game found its rhythm. And then we kept playing.

For over fifteen years, it’s been shared across tables, introduced to friends, and kept alive by a small, devoted following. Over the past year, more people have started finding their way to it. That’s still our favorite way for it to grow: someone plays, loves it, and brings someone else.

A little discovery in Croatia

On a trip to Croatia, one of us picked up a local deck as a gift for Superjack’s co-creator. Only later did we discover it had forty cards.

We’d arrived at forty through years of play. Traditional Italian and Spanish decks had been there all along. With a mapping for the local suits, colors, and court cards, many of those decks can have a second life as Superjack decks, too.

Made at the table. Kept alive by the people around it.

Before we deal

A few good
questions.

Do I need an official Superjack deck?

No. You need one standard deck per player. Remove the 8s, 9s, 10s, and any jokers to make each 40-card deck. Official decks give the game its own artwork and card reminders; everyone plays by the same rules.

Is this a deck-building or collectible game?

Everyone begins with an identical set of cards. There are no boosters or rare cards to chase. Your decisions and the shuffle make each game different.

Will I like it if I play chess, poker, or Magic?

If you enjoy planning ahead, making the most of your hand, and finding a clever response, there’s a lot here to explore. Superjack combines creature combat with familiar pairs, straights, and suits. Try it free in your browser or bring two decks to your table.

Can I use a Briscola or Spanish deck?

Many traditional 40-card Italian and Spanish decks have a compatible rank structure. You’ll need to agree on a mapping for their suits, the two game colors, and their court cards. Not every regional pack is the same; a standard French-suited deck is the simplest way to follow the official rules directly.

How can I get one of the new decks?

Explore Festival, Painted Court, and Gilded Oracle in the card galleries. You can play all three art editions online today. For a physical deck, tell us which edition you love and how many you have in mind; we’ll help with availability and ordering.
