A writer and mom of three is showing couples a new way to build a stronger relationship through sharing the workload at home. 

Eve Rodsky, author of the book "Fair Play," created a simple game that divides household tasks. All you do is shuffle the cards and play the hand that's been dealt to you.

Rodsky's method has been cheered on by celebs like Busy Phillips and Reese Witherspoon.

"My finding was the number one thing men hated about home life was nagging, and the No. 1 thing women said they hated was the mental load," she said. "'Fair Play' eliminates all that conception planning and execution."

Rodsky said she noticed there was an unfair divide in her and her husband's household responsibilities after her second child arrived.

"I got a text from my husband that had me sobbing on the side of the road and that text said, 'I'm surprised you didn't get blueberries,'" Rodsky recalled. "I had a breast pump in my passenger seat, returns for my new baby in the backseat, I have a client contract on my lap with a pen between my legs trying to mark it up as I'm going between traffic stops to pick up my first son from his preschool program."

"I was thinking, 'How did I become the default or the "shefault" for every household task?'" she said.

Rodsky went on a quest to figure out a solution for domestic re-balance. She interviewed 500 people in her research and found out about "invisible work."

"How do you value what you don't see? So if you could make the invisible visible ... things start to change," she said.

Rodsky developed "Fair Play" -- a time-saving system which offers couples a fun,new way to divvy up domestic tasks -- so it won't all fall on one partner.

In fact, a new Harvard University study says women hold the cognitive labor for household tasks.

With her research in mind, Rodsky came up with four rules, 100 household tasks and a figurative card game to play with your significant other.

"Fair Play" helps you prioritize what’s important to your family and who should own each responsibility. The cards have four suits, Home (handling dishes, groceries), Out (transporting kids), Caregiving (medical, dental appointments) and Magic (because it takes time to play Santa or the Tooth Fairy).

The cards are available for free download once you purchase the book and internalize the four rules to "Fair Play."

Here are Rodsky's four key rules.

1.) All time is created equal.

2.) Reclaim your right to be interesting.

3.) Start where you are now.

4.) Establish your values and standards.

"For me it started with extra curricular sports," Rodsky said, adding her husband chose to own this responsibility in their own game of "Fair Play."

Rodsky said if one person owns a card like extra curricular sports, then that person is responsible for it all: registering the children for their activity, xeroxing paperwork, providing snacks and arranging car pools for practice.

"Once husband understood that it required full ownership, I got 8 hours of my week back," she added.

Bonus tip: "Understand that you are already communicating."

"A woman who told me she was afraid to talk about invisible work and fair play was the same person who told me she dumps wet clothes on her husbands pillow when he forgets to put them in the dryer," Rodsky said. "It's a conversation shift, not a conversation start."

"Shift the conversation to something productive," she said.

"Fair Play" is out now.
