Card Vault – Twelve Cards

Starting your session.

After checkout, access to the game is assigned to your personal account. Open it in your browser, start the session yourself, or invite others using the game code provided. Every participant must have their own verified account. The maximum player count is a limit rather than a minimum, so you can complete the game by yourself. A purchase gives access to one complete play-through; another run requires a new purchase.

How the experience works.

The story unfolds across eight connected stages. Read clues, compare information and select the answer that best fits the evidence available. Answers are validated on the server so solutions are not revealed in the browser before play. If a stage proves difficult, the built-in hints can help. The indicated playtime is a guide, not a guaranteed duration; different players and groups may work at different speeds.

Playing alone or with a group.

Solo players can make their own decisions and follow the story at their own pace within the rules. Groups can discuss details, compare interpretations and solve challenges together. A current browser, a reliable connection and a shared display for groups can make the experience easier. No application download is required. The site provides both German and English navigation, which can be changed at any time.

Price, account and result.

The published price is the final amount in Swiss francs and includes 8.1 percent Swiss VAT. Checkout and the invoice show the net charge, tax and total separately. There is no automatically renewing subscription and no fee per puzzle. Results are associated with your account. Publishing or sharing an achievement is optional and will not reveal a private email address to the public.

Practical questions.

Both private customers and Swiss businesses can purchase a session, provided the billing address is in Switzerland. Only the host needs to purchase a shared game; every participant signs in individually. No wagers, gift vouchers, cash payouts or prizes of monetary value are offered. You can contact support about payment, invoices and technical issues through the website. Personal results and achievements can be reviewed later from your account.
