1. Fight, Friend, Eat

1. 1. Fight, Friend, Eat

For the The Big Bang Theory gang, their genius brains aren't stimulated by the average board or card games. That's why, over the years Raj, Howard, Leonard, and, of course, Sheldon have stepped up to create a unique archive of activities that test their own knowledge and provide endless hours of fun. 

The latest game was revealed on the episode entitled "The Platonic Permutation" when Sheldon introduced "Food, Friend, Fight," which is where one player names three aquatic creatures and the other must identify which he or she would eat, befriend, or battle.  

In honor of this newly-minted romp, we decided to round up 10 other concocted amusements courtesy of The Big Bang Theory and explain how to play them at home!

2. Three Person Chess

2. 2. Three Person Chess

Although three-person chess exists, Sheldon upped the ante by adding new place pieces as we saw in "The Wildebeest Implementation" (Season 4, Episode 22). 

How To Play:
The complex game uses a three-sided board that includes a central combat area with similar checkmate rules for capture, move order, and game objective. The game has been played a few times on the show, each instance revealing new pawns and rules that Sheldon has added like:
The Serpent: It slithers to—and poisons—an opposing player's piece, meaning it will die after two moves. But, if it can make it to the old woman, who can suck out the poison in those moves, then the piece becomes the Grand Empress, which combines the power of the knight, queen, and serpent.

Prince Joey: As the king's simple-minded cousin, there's a 1-in-5 chance he'll kill himself—though, it's unknown if this piece was implemented or if he killed himself.

Flinging pieces: Sheldon introduced the flying bishop by using a catapult.

Queen's Gorilla Two: It's not exactly clear how to use this piece, but Sheldon plays it during one turn.

Spinning Wheel: The new location of the piece is decided by spinning a wheel with place locations on it. 

Golf Cart: Even Leonard is confused by the game and asked when he could use this piece, to which Sheldon responds, "When it's done charging." But, when a piece lands on the time machine, the golf cart can be used without waiting for it to charge. 

Pope: When this piece is captured, you can release a swarm, which can cause checkmate. The Pope is also able to have a jet pack. 

Beekeeper: This pawn was moved by Leonard to King 12, allowing him to capture the Pope, release the swamp, and checkmate Sheldon. 
​3. Counter-factuals

3. ​3. Counter-factuals

The rules of this game are fairly simple, according to Sheldon and Amy, who explained them on "The Zazzy Substitution" (Season 4, Episode 3). 

How To Play:
You "postulate an alternate world that differs from ours in one key aspect, and then pose questions to each other." Then, you answer that question as if you were in that alternate scenario.

Some examples include:
Question: In a world where rhinoceroses are domesticated pets, who wins the Second World War?
Answer: Uganda
Reason: Kenya rises to power on the export of rhinoceroses. A central African power block is formed, colonizing North Africa and Europe. When war breaks out, no one can afford the luxury of a rhino. Kenya withers and Uganda triumphs.

Question: In a world where a piano is a weapon, not a musical instrument, on what does Scott Joplin play the "Maple Leaf Rag?"
Answer: Tuned bayonets
Reason: Isn't it obvious?

Question: In a world where mankind is ruled by a giant intelligent beaver, what food is no longer consumed?
Answer: Cheese danish
Reason: In a world ruled by a giant beaver, mankind builds many dams to please the beaver overlord. The low-lying city of Copenhagen is flooded. Thousands die. Devastated, the Danes never invent their namesake pastry.
4. Secret Agent Obstacle Chess

4. 4. Secret Agent Obstacle Chess

Leonard, Howard, and Raj first play this game in "The Work Song Nanocluster" (Season 2, Episode 18).

How To Play:
While the basics of chess seem to remain the same, prior to a player making a move, they must navigate through a series of laser beams that are only visible when sprayed with a mist.
5. Research Lab

5. 5. Research Lab

"Research Lab" is a board game created by Sheldon where the tagline reads, "The physics is theoretical, but the fun is real," and was revealed on "The Guitarist Amplification" (Season 3, Episode 7).

How To Play:
The board features spaces that are configured into the shape of the Bohr model of the atom.

To make a move, you roll the dice to move onto a space, where you can you draw a card that benefits you, hurts you, or hurts other players.

These hurtful outcomes include disasters such as a nuclear meltdown, industrial accident, and/or a loss of a retina by staring into a helium-argon laser. Benefits include a renewal of a Department of Defense research grant.
6. Chutes And Lawyers

6. 6. Chutes And Lawyers

Sheldon revealed this game on "The Mommy Observation" (Season 7, Episode 18).

How To Play:
The rules were described very simply as, "You slide down a chute and then work your way back up through the appellate system."
7. Mystic Warlords Of Ka'a

7. 7. Mystic Warlords Of Ka'a

Sheldon and Raj compete in this fantasy card game tournament against Wil Wheaton in the episode "The Creepy Candy Coating Corollary" (Season 3, Episode 5). 

How To Play:
Similar to the rules of "Magic: The Gathering," this card game pits player against player in an attempt to reduce the opponent's health and, ultimately, win duels and battles.

Each card has a rune (color) and rank (number), where higher ranks and runes overrule lower ones. 

When one of the players has their health reduced to zero, they lose. 
8. Rock Paper Scissors Lizard Spock

8. 8. Rock Paper Scissors Lizard Spock

When Sheldon and Raj can’t decide on what to watch on TV, they implement this game as a decision maker on "The Lizard-Spock Expansion" (Season 2, Episode 8).

How To Play:
Like "Rock, Paper, Scissors," this game adds the elements of a lizard and Mr. Spock. Each player has to choose a variable and display it at the same time as the others are playing. This is done until a winner is determined. The trump order goes:

- Scissors cuts Paper
- Paper covers Rock
- Rock crushes Lizard
- Lizard poisons Spock
- Spock smashes Scissors
- Scissors decapitates Lizard
- Lizard eats Paper
- Paper disproves Spock
- Spock vaporizes Rock
- Rock crushes Scissors
9. Elements Letters

9. 9. Elements Letters

Sheldon attempts to play this car game with Penny, but ends up playing by himself, in "The Euclid Alternative" (Season 2, Episode 5).

How To Play:
One player begins by saying an element, then the other player says an element where the first letter starts with the last one that the first player said.

For example, player one says "helium," which ends in "m" and means the next player could say "mercury." That would mean player one would have to come up with an element beginning in "y," and so on. 
10. Trestling

10. 10. Trestling

The guys first play this physical-yet-mental game for the first time on "The Peanut Reaction" (Season 1, Episode 16). 

How To Play:
Players must play a game of Tetris with one hand while wresting their opponent with the other.

The winner is the first to beat the other in either.
11. Emily Or Cinnamon

11. 11. Emily Or Cinnamon

Howard introduces this game to Leonard and Raj on "The Anxiety Optimization" (Season 8, Episode 13).

How To Play:
A leader gives a quote and the other players must decide if it was something Raj said to his girlfriend Emily or his dog Cinnamon.

For example:

Quote: "I want you to know the bed feels so lonely without you in it."
Answer: Cinnamon
