Stereochemistry Race - English on PlayingCards.io

Rules

The game can be played by 2 to 4 players. Each player must select a colored game piece of their choice. Each player must follow their trail, which is made up of 16 houses, four houses with four different colors, with specific tasks:

• Red: the player must classify a statement as true or false.
• Green: the player must determine the absolute configuration (R or S) of an asymmetric center indicated by an asterisk in a molecule.
• Yellow: the player must classify a molecule as chiral or achiral.
• Blue: the player must classify compounds as equal, constitutional isomers, enantiomers, or diastereoisomers. To travel along the trail, the player must correctly execute the above commands until reaching the trail's end. The one who completes the entire trail first becomes the champion.

How to Play

1. Initially, one of the players must click on the "Who starts" die (Figure 1a) to determine who will play first (Figure 1b). Then, the others will follow the order of the pieces on the board, considering the direction from top to bottom from the drawn piece.
2. The trail starts with the color red, so players must click the "Draw" button located on the red atom (Figure 1b) while their pieces are positioned on a red square. During the game, the player must click the "Draw" button on the atom with the same color as the house where their piece is.
3. When clicking any "Draw" button, a card will be moved from the deck to the right side (Figure 1c). Tip: to enlarge the card, the player should hold their finger on the card on smartphones or tablets. On computers, position the cursor on the card. However, in all cases, the player should not click the card to avoid flipping it and revealing the answer.
4. The player must then respond verbally to the command on the card.
5. To check whether the answer given is correct, the player must click on the "Answer" button (Figure 1d), turning the card over and revealing the correct answer.
6. If the player misses, they do not move their piece and pass the turn to the next player.
7. If the player got the answer right, they have two options:
   • A. Advance your piece one position on the track or
   • B. Try your luck by clicking the "Try your luck" die (Figure 1e) with faces. There are three options on the faces of the die: pass the turn (3 faces), turbo (1 face), and box (1 face). If the face drawn is "pass the turn", the player advances their piece one position and passes the turn to the next player. If the face drawn is "turbo", they advance their piece two positions and pass the turn to the next player. If the face drawn is "box", they advance their piece one position and pass the turn to the next player but do not play in the next round.
8. The game continues this dynamic until the first player reaches the area where the trophy is, therefore becoming the champion.
