# Mix up family game night with Proof!

## What is Proof?

Proof! is an award-winning, fast, fun, and addicting card game that the whole family can enjoy! For 2 - 6 players, ages 9+, and taking only 15 minutes, Proof! will have you showing off both your math skills and creative thinking as you race to find equations hidden among nine number cards.

Got the cards 2, 8, and 10? Concoct an equation like 10 - 2 = 8!

Working with 2, 5, 5, 10, and 20? Conjure up a beauty like 5 + 5 = 20 ÷ 2 = 10!

Allowing you to use almost any math symbols and all sorts of crazy equations, Proof! is unlike most math games: engaging for both students in a classroom and adults at a party.

Proof! is also the inspiration behind our infamous online Math Puzzle Challenges. For the more puzzle-minded players out there, each week we post a new set of nine cards that hides a challenging equation. See if you can find the proof!

Full game instructions for the card game can be found here.

Still can't get enough Proof! in your life? Check out the free, online game where you can compete with friends to rise up on the daily leaderboard. Or get those gears turning with one of our 300+ brain-benders called the Proof! Math Puzzle Challenges. Each carefully constructed puzzle consists of a set of nine cards that hides a challenging equation. Can you solve them all?

Proof! was created by Evermade in New York City. And if you like Proof!, you may also enjoy our other math game, Adsumudi.

## How do you play?

One player volunteers to be the dealer, shuffles the deck, and then places nine cards face up as a 3-by-3 grid in the center of the table. At the same time, all players (including the dealer) study the cards in the grid and try to create an equation using at least three cards and as many math symbols as needed. For example, the cards 2, 4, 7, and 1 above could be arranged to make 2 + 4 = 7 - 1.

When a player finds an equation, she shouts the result, such as “Six!”, which immediately locks out all other players and gives her a chance to prove that the math works. If the proof checks out, she takes the three or more cards that were involved and keeps them in front of her.

Every time an equation is found, the dealer replaces the cards that were taken with new ones so that there are always nine cards face up in the grid. Players continue finding equations until all the cards in the deck are used up and no more equations can be found.

Once all the cards in the deck are gone and no more equations can be made, the game is over and players count up their points. Each card is worth 1 point and the player with the most points wins!

## Has Proof! won any awards?

Yes!

Proof! (along with our other math games) most recently won the 2024 Family Choice Award as an "exceptional product that enriches a family’s lifestyle and creates memorable experiences." The Family Choice Awards further commented, "The creativity and extraordinary imagination utilized to develop new products and enhance existing products for the benefit of consumers, continues to amaze our distinguished judges and staff."

Proof! has also notably won the 2019 Teacher's Choice Awards, with its teacher evaluators raving that Proof! is "an awesome, fun game for students to engage in while learning math" and that they "would definitely recommend this game" for use in the classroom and at home.

Further awards include a Parent's Choice Silver Award, the Academic's Choice Brain Toy Award, and the Creative Child's Game of the Year Award in 2020.

Proof! also participated in the 2018 Mensa Mind Games competition, and many of its brainy members gave it top marks saying, "LOVE this game!", "Fast moving and different!", and "A real thinking person's game!".
