Enter an ancient observatory where every Door hides a secret rule.

The Secret Vault is an adventure-filled card game of observation, visual logic and strategic thinking for children aged 10+, teenagers and adults. Players examine mysterious Door carvings, work out how each rule changes a symbol and choose the right route to unlock valuable treasures.

Every symbol combines four visual details: arrow direction, gem position, inside or outside placement, and gem shape. Door cards may rotate, reflect or transform these details. Players must follow the changes carefully and predict the final symbol before committing to a raid.

Search for useful Artefacts, study uncertain Doors, rearrange the passage or scout for a better route. Use your once-per-game Compass wisely, because a well-timed quarter-turn could open the perfect lock.

Collect at least 12 treasure points from three of the four lost galleries—Sun, Moon, Sea and Forest—to trigger the final round. The highest-scoring qualifying explorer wins.

The game also includes:

• First Expedition mode for learning the rules together

• Experienced Explorers mode with routes of up to three Doors

• Cooperative mode where the whole family races against an eight-turn countdown
