Scientia is a tactical game for 2~4 players who compete to develop in four scientific fields: physics, chemistry, biology and astronomy. The game includes three different cards from each field, and each card has two different sides, so there are 24 effects for a game. On a turn, a player can choose one of two options:
- Take a card and place it in front of their personal board as long as it does not exceed its slot limit. There are two slots at the beginning of the game, and more can be added during the game.
- Rotate one card twice (180º) or two cards once (90º each).
If a card is fully rotated (360º), that card is moved to the completion area. As soon as a card moved to the completion area, do this process:
1: Advance the research marker of that card's field.
2: If the research marker has reached the rightmost space of a track, take the score tile.
3: Apply the card's effect.
4: Put the card back in the center's appropriate position. If that position is empty, flip it before placing it, making a new effect available.
The game ends if all flasks (cubes) run out or all scoring tiles run out. Then calculate various scoring factors: cubes, research markers, fields, scoring markers, etc. All cards are always visible to all players.
