The innovative FlagMath game is the latest to be designed and published by the 7puzzle company; a refreshing, new matching card game with just one simple rule to learn.


Our exciting FlagMath game requires excellent concentration and visual skills to enable players to practice arithmetic in a fun and non-threatening way. The cards can be used at school or home and particularly as a resource during one-to-one or small group maths tuition sessions.

And the one simple rule – players must attempt to find the exact same world flag and mathematical answer from the pair of cards placed on the table.

The first four versions of the main card game, Addition, Subtraction, Multiplication & Division, are available to purchase from this site as well as the four editions of the FlagMath junior game, described in detail further down the page.

Object of the Game

There are 12 cards in each pack. Each card contains the same 12 world flags. Each flag is linked to a mathematical calculation, or answer, as shown below:

Any two cards placed at the centre of the table will always have one (and only one) combination of flag and numerical answer that is exactly the same.

All players play at the same time. Be the first to find the correct pair and state the country and mathematical answer. If correct, the player takes one of the cards as a reward. When all the cards have been used up, the player with the most cards is the winner.

So can you find the matching pair on the two cards taken from the Division pack above? The answer can be found at the very bottom of this page. Don’t peek yet!

Remember, both country AND mathematical answer must be the same on both cards!

Game Play

Shuffle all cards and place in a pile face down on the table.

The referee, or oldest player, takes the top two cards from the pile and places them face up in the centre of the table next to each other. The game begins.

All players immediately look for the same flag and answer. If a player believes they have found the pair, they quickly call out that answer. If correct, they receive one of the two cards and keep that card as a reward for winning that round.

Any player who is incorrect are now out this round and the other players continue to look until someone finds the correct pair.

A new card is then taken from the pile of face-down cards and placed face up next to the other card on the table. Any disqualified players from the previous round are back in the game, and all players immediately start looking for another pair in the same way as before.

Full game rules and instructions, as well as the identity of the twelve countries and their flags, are shown on the inside cover of each pack.FM5

End of the Game

The game continues until the two cards that are face up on the table are the only two cards left. The winner of this last round wins BOTH cards. The player with the most cards at the end of the game is the winner. If two or more players have the same number of cards, the pack is re-shuffled and a sudden-death play-off takes place between those players using two new cards face up on the table. One wrong answer here and you lose!!

It is possible to play FlagMath many times over and never have the same pair of cards on the table, therefore making for a different game each time! Make sure you shuffle them well.

A review of FlagMath

g4edWe recently received this review from an organisation in the United States who specialise in reviewing educational games.

The owner of the aptly-named Games for Educators organisation, Patrick Matthews, played the Addition version of the game with some children, always the most honest reviewers, and we were extremely pleased with the feedback.  We’ve already taken on board his advice about the front cover!

Please click this Games for Educators link to read Patrick’s thoughts.

Bookstores, Toy Shops, Educational Shops

Just a short note as a continuation from the above review.  We are in the process of looking for any stores who may wish to stock the FlagMath series of card games, so please get in touch by e-mailing us if you wish to be involved in selling this unique game.

Alternative ways of playing FlagMath

You could even play with single cards where players have to find the smallest mathematical answer or largest mathematical answer, for example, on each of the 12 cards. This works with whichever version of the game is used.

You could ask players to find the smallest/largest answer on alternate cards or even get groups of children to quickly add up the answers in particular rows or columns in a mathematical race. This helps to quicken players’ mental maths skills in a fun way and keep the game fresh and interesting.

FlagMath competitions

In a fun competition environment, each team would receive a different card to work with and try to be the first to find a particular total (2nd row, or right-hand column, etc.).

As an example, the ‘South Korea’ card (flag in top left corner, see below) has a top row total of 16+6+13 = 35, a 2nd row total of 42 , 3rd row 39 and bottom row 52.

Teachers could make a note of the sums on each card and then set a class competition to find the first team/group to find the total of a particular row on their card.

This concept will work with any of the FlagMath editions.

. . . and Bingo?

flag9Kids love Bingo.  I always get asked if we are going to play Bingo when bringing out any kind of numerical cards in my classroom sessions.

One way we can use the FlagMath Addition cards is to allocate each group of children a card which will act as the equivalent of their Bingo card. It is up to the teacher to design numbered balls (or something similar) from 4 to 24 as all 12 answers on each card are in this range.  The organiser would also need to give 12 counters to each team.

The teacher will call out the numbers randomly and players ‘do the math’ by covering the mathematical equivalents on their card as the numbers are called out. Teams have 30 seconds to place their counter.

Similar to Bingo, the winner is the first team to cover all twelve flags with their counters.

Purchasing Options

The editions currently available are:

1.  Addition
2.  Subtraction
3.  Multiplication
4.  Division

Every edition has 12 different countries, so 48 countries are represented in the first four editions.

Each pack of FlagMath cards retails at £12 and when ordered will be packed in our special flag wrapping paper to your chosen delivery address.

Should you wish to make a purchase, please send us an e-mail.

FlagMath junior-L

The four editions of the brand-new FlagMath junior game now retail at just £10 per copy and involves exactly the concept of playing as the standard FlagMath game, but with the maths being suitable for little ones aged 5 years and above.

The first three arithmetic editions listed below contains only six UK/Ireland flags and arithmetic calculations per card, but the popular FlagSnap edition will have 12 different flags on each card (80 world flags throughout the whole game – and no maths), so younger players get used to the quantity of flags to observe on each card before progressing to the more advanced FlagMath games.

The four Flagmath junior editions are:

J1.  Number Bonds up to 10
J2.  Basic Subtraction
J3.  2, 5 & 10 Times Tables
J4.  FlagSnap

Get in touch to order one or more copies that the younger ones will thoroughly enjoy.
