## Components

• 118 Elements Cards
• 10 Game indicator cards
• Instructions

## Setup

Place the Game Indicator Card to one side. Shuffle the remaining cards.

• Deal 5 cards face down to each player.
• Place the remaining cards in a face down pile in the center of the table to make the "draw pile".

Turn the top card from the "draw pile" over, and place it face up in the center of the table. This card will be known as the Mendeleev Card.

• Each player looks at the cards that have been dealt to them, but you must be sure not to let the other players see your cards.

• Decide who is going to go first; this is usually the youngest player.

## Game Play

The first player takes the Periodyx Game Indicator Card and plays the first game on the list, acting as the lead player for this game.

After each round, the Periodyx Game Indicator Card is passed to the player on the left who becomes the lead player of the next game on the list.

The Periodyx Game Indicator Card (shown above) is passed around all the players, each one leading the next game on the list.

When a player gets to the end of the list, the next player begins at the top of the list again, this continues until the game is over.

The player who has the Periodyx Game Indicator Card is called the lead player in the rules below.

The rounds listed on the Periodyx Game Indicator Card are:

### Game 1, Atomic Power

The lead player asks ONE OTHER player to choose a card in their hand and to read out loud that element's name (do not show the card). The lead player then chooses a card from their hand and reads out loud the element's name. Both cards are now compared.

The player whose card has the HIGHER Atomic Number wins takes both cards and adds them to the cards in their hand.

This ends this lead player's turn and play moves on to the next player.

### Game 2, A-2-Z

The new lead player picks any letter of the alphabet and then asks ONE player of their choice if they have an element beginning with the letter they have named.

If the asked player DOES have an element that begins with the letter the lead player asked for, they must give the lead player the card (or cards if they have more than one that begins with the asked for letter). This ends the lead player's turn, and play moves on to the next player.

If the asked player DOES NOT have an element that begins with the letter, the lead player asked for, the ASKED player takes the top card from the "draw pile" and adds it to the cards in their hand.

This ends this lead player's turn, and play moves on to the next player.

### Game 3, Hot Stuff

The new lead player asks ONE OTHER player to choose a card in their hand and to read out loud that element's name (do not show the card). The lead player then chooses a card from their hand and reads out loud the element's name.

Both cards are now compared. The player whose card has the HIGHER boiling point wins takes both cards and adds them to the cards in their hand. This ends this lead player's turn, and play moves on to the next player.

### Game 4, Hi-Lo

The new lead player takes any one card from their hand, and places it face up in front of them.

From this card the lead player chooses ANY ONE of the stats from in the Stat Section (except the date stat) and predicts whether the next card turned over from the "draw pile" will have a higher or a lower number in the same stat.

Once the prediction is made, the top card from the "draw pile" is turned over, and the two cards are compared.

If the lead player has predicted correctly, they take both cards and adds them to the cards in their hand. If the lead player has predicted incorrectly, both cards are given to the player on their left.

This ends this lead player's turn, and play moves on to the next player.

### Game 5, Neutron Countdown

The lead player asks ONE OTHER player to choose a card in their hand and to read out loud the name of the element (do not show the card). The lead player then chooses a card from their hand and reads out loud that element's name

Both cards are now compared. The player whose card has the HIGHER number of neutrons wins takes both cards and adds them to the cards in their hand.

This ends this player's turn, and play moves on to the next player.

### Game 6, Add-it

The lead player takes the top card from the "draw pile", and adds it to the cards in their hand. This ends this lead player's turn, and play moves on to the next player.

### Game 7, Big-freeze

The new lead player asks ONE OTHER player to choose a card in their hand and to read out loud that element's name (do not show the card). The lead player then chooses a card from their hand and reads out loud the element's name.

Both cards are now compared. The player whose card has the LOWER melting point wins takes both cards and adds them to the cards in their hand.

This ends this lead player's turn, and play moves on to the next player.

### Game 8, Element of Surprise

The lead player asks ONE OTHER player to hold out their cards fanned-out, facedown. The lead player then takes ANY ONE card from the asked player and adds it to the cards in their hand. This ends this lead player's turn, and play moves on to the next player.

### Game 9, Early Bird

The lead player takes ANY card from their hand, and places it face up in front of them. They then predict whether the next card turned over from the "draw pile" will have an earlier or later date of discovery than their card.

Once the prediction is made, the top card from the "draw pile" is turned over and compared. If the lead player has predicted correctly, they take both cards and add them to the cards in their hand.

If the lead player has predicted incorrectly, both cards are given to the player on their left. This ends this lead player's turn, and play moves on to the next player.

### Game 10, Match

The lead player takes ANY card from their hand, and places it face up in front of them. They then ask ONE OTHER player to do the same.

Now, ALL of the players play at the same time and try to be the first player to spot how the two cards match or are the same in any way. Are they both metals?

Both solids? Do both element names begin with the letter 'P'; any similarity can be a correct match. The first player to spot the match keeps both the matched cards this can be ANY player. This ends this lead player's turn, and play moves on to the next player.

### Game 11, Natural/Synthetic/Radioactive

The lead player takes ANY card from their hand and places it facedown in front of them. They then ask ONE OTHER player to do the same. Both cards are turned over, face up at the same time. Check the Natural/Synthetic/Atomic symbols at the bottom of the cards:

The winner takes both cards and adds them to the cards in their hand. If it is a tie, both players keep their cards. This ends this lead player's turn, and play moves on to the next player.

## The Mendeleev Card

If on a player's turn (before taking their turn), they can place a card next to the Mendeleev Card so that the colored bars match (see example) they may play that card on the table and draw two cards from the "draw pile".

If there are 2 or more cards in play on the table (this begins to form the periodic table). Any cards that match any of the cards can be played in this manner, drawing two fresh cards for each card played.

## End of the Game

Two ways to end the game:

1. The first player to collect TEN cards in their hand immediately stops and wins the game!

2. The first player to lose ALL the cards in their hand stops the game.

The player who, when the game is stopped, has the highest number of cards in their hand is declared the winner. In the case of a tie, the player who has the card with the highest Atomic Number wins.

##### Ties or N/k

If during any round of play the stats are tied, the round is void, this ends the lead player's turn, and play moves on to the next player, and the next game on the Periodyx Game Indicator Card.

If there is an N/K (not known) on a card, this round is void. Players have the option to keep a card with an N/K or to exchange it by returning it to the bottom of the draw pile and taking the top card from the draw pile.
