Play Free Weekly Math Puzzles to Practice Your Mental Math Magic

Most of us aren't born with mental math magic. We develop it overtime through regular practice. Playing fun math games with friends and family helps of course, but if you'd like a little extra practice, check out our free weekly math puzzles. 

Practice Your Mental Math Powers with Free Puzzles Online

Proof! is the inspiration behind our infamous, free, online game, the Weekly Challenge Math Puzzles. 

Every week on Monday, we release a new math puzzle to help you stretch your brain and flex your math muscles. Each puzzle contains a new set of nine cards that hide a challenging equation. You might be tasked with finding a specific answer or using only one operation.

Some puzzles are more advanced and may be better for adults than children, or may require a team effort to solve.

Here are some examples of the types of challenges you'll find:

In this challenge, you're looking to create a "pair", which means any two of the same number on the board at the same time. However, you're also only allowed to use division to create that pair.

For example, if you had the cards 6, 2, 9, and 3 you could create a pair of 3's with 6 ÷ 2 and 9 ÷ 3. To do so, you would click the 6, then the ÷, then the 2. Then you would click the 9, then the ÷, then the 3. Once the two 3's were on the board, the game would detect the match and you'd win!

In this challenge, you're looking to create a "pair" of 6's, which means two 6's on the board at the same time.

For example, if you had the cards 2, 4, 7, and 1 you could create a pair of 6's with 2 + 4 and 7 - 1. To do so, you would click the 2, then the +, then the 4. Then you would click the 7, then the -, then the 1. Once the two 6's were on the board, the game would detect the match and you'd win!

How to Play Proof! Math Puzzles 

The Proof! Weekly Challenge Math Puzzles play exactly like the classic Proof! card game, except each week you're challenged to find a specific type of equation, rather than just any equation at all.

To play, first read the title of the challenge to understand what you're looking for. (Click the  if you need more of an explanation.)

Then, start solving it by clicking a card, then a math symbol, and then another card to combine those cards using that operation. Once you create two or more cards with matching values (called a pair, triplet, etc.) that fit the bill for the challenge, you'll win!
