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, thus a game can show 12 different effects. On their turn, players 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, follow this process: 1: Advance the technology token of that card's field. 2: If the tech token has reached the rightmost space of a track, take another tech token from reserve and place it on the first space of that track. 3: Apply completed card's effect. 4: Put the card back in the center's appropriate position. The game ends if all flask tokens or all tech tokens run out. Then calculate various scoring factors: flask tokens, tech tokens, fields, etc. All cards are always visible to players and this is the game with no luck element. No random cards draw, no hidden components or no rolling dice. In a game, always use 12 types of cards among 48 types. So every time in play, players are needed to set the strategy regarding the combination of visible cards.
