Fun to play as a family! Was very adaptable for playing with my elementary school kids who needed practice with mental math. As they learn more, we will add the more difficult versions of the game. Easy to use and learn, and helps everyone learn as you play. Our game arrived in good condition. Cards are nice quality, good size. Would recommend for fun or for educational purposes.

I am a teacher and my students love this fast paced game. It’s allows them to be competitive and practice math skills.

I have played a dozen different math related games - Proof is the best

1. The pace is perfect: Everyone is involved and engaged, the board constantly changes, so even when you get stuck with certain numbers, someone else has a solution and new numbers appear on the table and everyone can start calculating again.

2. Duration: It never gets boring. A typical game last 10 min, so you can play best of three or five and have a new chance to loose or win

3. Easy to learn: Everyone understands the game within 2 min, set up is super simple and you can just enjoy the game. You can play it at the table, on the beach, in the train - everywhere.

I do like games like 24 or Target. They are also great math games, but Proof is just more fun because it is faster and easier to learn. My friends enjoyed it so much that I already gifted over 8 Proof games to friends, friends of friends and family members in all age groups.

This was a great brain workout for all of us even me as an adult!!! Definitely targeted for older children, will really get your brain thinking and your human calculator whirling away! We got really competitive as we all sat trying to find an equation!!

Fun game!

It is a great game. Sharpens math ability of all levels. Play with basic facts/moderately hard facts for 8 years old (8X9= 72.... 24+25=49....)

As your kids get better in math, they will make harder equations... 7X9+3X10=93.....

You can play with kids of all ages, and you can modify the rules according to the ability of the players. (we play with my high school children)

This is also a good game to play in a math class, if you have stations set up.

Our homeschool friends highly suggested this game. We played once on our homeschool community day. The kids struggled at first because they couldn't come up with an equation as fast as when they solved it on paper. The more you play, your math skills level up. I need to start playing with my kids more often. My oldest always says that his brain is fresher and younger. That is why he can memorize things faster and remember things faster. I need to show him my brain is not old. Learning does not have to be boring. This can be a fun family math game to play!

This is a decent game for math practice, not something my kids request to play though. I will say, I feel it is priced high for essentially getting two decks of cards. If it was priced a bit lower, it'd be more worth what you get.

A versatile, fun and unconventional card game for anyone wanting to practice mental math skills, ranging from basic addition equations to fractions, parentheses and square roots… I admit, I was rusty on some equations! Find an equation, shout out the result and show your proof to gain points. I have played this game with students ranging from 8 to 16 yrs so far and they have all loved the competitiveness and challenges of the game by adding in more complexe math equations. A fun favorite during indoor recesses and solicited as a top choice class incentive! Adaptability is easy by determining the goal and card numbers at the beginning of each game.

A home AND class favorite!

El juego para lo que es, es bastante caro. Son solo cartas

La règle du jeu est uniquement en anglais donc il faut que je chercher sur internet comment jouer .. dommage qd mm!

Well-thought out game. Would have liked more smaller numbers in set. Pricey for what was supplied. Paying for the idea I suppose.

Very expensive for what it is - but students love the game!
