When chess meets card collecting

In SPIRAVIUM, the cards have unique effects and don't stand still: they're played onto a field of twelve squares and move like chess pieces. Every step changes the match.

  1. One step at a time

    Each creature moves one square per turn, in any direction, or attacks a nearby opponent: if its LVL is higher, it defeats it and takes its place.

  2. Effects and combos

    Combine your creatures' effects as well as you can to gain advantages and territory, or to complicate your opponent's plans.

  3. No life points

    Reach the opponent's home row and, from your next turn, strike them directly. If nobody stops you, the match is yours.

There's nothing to buy in the game

  • Gems aren't for sale

    One arrives every day, and you win more in the campaign and the tournament.

  • We don't sell Limited Editions

    They're only born when a final is won. Then they're yours: pass them on to anyone you like, even on loan.

  • Tips buy nothing

    They keep the servers running until the game's mature P2P phase.

From guest to the final

  1. Open it and play

    You're born a guest, with three creatures: ATTHIS, INDICA and TROGLO. Your account is 12 words. You write them on paper, and nobody will ever ask you for them.

  2. A gem a day

    A creature sleeps in every gem. Collect today's gem and awaken a new card for your collection. Tomorrow another one arrives.

  3. Ten leagues against the master

    Your first win in each league is worth two gems. With the campaign you reach 27 different cards on your first day: it's the deck that opens up online play.

  4. The World Tournament

    Like the tennis tour: you face someone on the same winning streak as you, best of three. If nobody's there within a minute, the master steps in, and we tell you so.

  5. The final

    Whoever wins it takes home a numbered Limited Edition. Limited Editions are born only this way, and the prize arrives right away.

  6. Take it out of the game

    Print it in the rarity you like, with the Factory kit, and photograph the front and back: the photo goes on the card's page, and its fingerprint into the registry. You can hand it to a friend with a link or an NFC chip, even on loan, for 1 to 60 days.

Don't trust. Verify.

The registry fingerprint

The first fingerprint comes with the first Limited Edition: the registry closes its first day at midnight UTC after it's born.

Every day something happens to the Limited Editions, the registry is sealed into a 32-byte fingerprint, and the fingerprint goes onto Bitcoin.

Every Limited has its own certificate, a few KB in size. You check it on the card's page, or on your own with a Bitcoin node, without asking us anything.

The registry holds only keys, cards and numbers. Never names.

Matches can be checked too: each one replays, move by move, with the engine it was born with.

The Limited Editions born so far

A hundred years in the dark. Whatever it loses, it grows back, and it's in no hurry.
