Adsumudi is a math monster on a mission to make math fun with its namesake game.

To play,
**find the secret math path to Adsumudi’s answer**
on each card by
**adding, subtracting, multiplying, and dividing**
the five other numbers. Keep the cards you figure out first and
**collect 5 to win!**

*
Psst! Can you figure out how Adsumudi got its name? Hint: it has to do with
ADdition,
SUbtraction,
MUltiplication, and
DIvision!

With its compact design and durable cards, Adsumudi is also the perfect math game for kids to take on the road, whether you’re traveling by car, plane, train, or boat!

From the makers of the award-winning math game, Proof!, Adsumudi has quickly become another favorite among parents and math teachers alike.

Adsumudi can be played by kids and adults of all ages.

For practicing math facts, the classic Adsumudi math game is recommended for
**grade 3 and up (ages 9+).**
It's best suited for kids who are familiar with addition, subtraction, multiplication, and division. That said, we've seen math whizzes as young as 5 outplay their older siblings!

In each game, all cards have a
**star ranking at top**
indicating general difficulty level, where 1 star is the easiest and 3 stars is the hardest. So you can split up the deck for players of different abilities. In addition, each card has multiple math challenges ranging from easy to monstrously hard, so there’s something for everyone.

Adsumudi is the perfect complement to math worksheets and flashcards. We’ve been told it’s a monstrously fun way to master the “Operations and Algebraic Thinking” objectives from the Common Core State Standards.

A brief description of how to play the classic game can be found below. You can also find the full
**Adsumudi classic instructions**,
**Adsumudi Fun Ones instructions**,

To play classic Adsumudi, each player first chooses their own difficulty level for the game. Adsumudi recommends that
**anyone who hasn’t played yet should start off on easy,**
then gradually move up to
**medium,**
then
**hard,**
then
**monstrously hard.**
Players in the same game don’t necessarily have to play at the same difficulty.

Get started by placing the entire stack of cards in the center of the table.

At the same time, all players focus on the top card and try to
**create Adsumudi’s answer**
(the number in the center) using the five other numbers on that card.
**Numbers can only be used once each**
in a given equation, but players can use
**any combination of addition, subtraction, multiplication, and division**
they need.

If a player is playing on
**easy,**
they can use any
**two or more**
of the five numbers to make Adsumudi’s answer. If on
**medium,**
they have to use
**three or more.**
If on
**hard,**
they have to use any
**four or more.**
And if they’re playing on
**monstrously hard,**
they have to use
**all five numbers.**

*
For example:
Pretend that the five numbers on a card are 1, 2, 3, 4, and 5, and Adsumudi’s answer is 6. If you’re playing on
easy,
you could come up with
1 + 5.
Or on
medium,
you could use
4 x 3 ÷ 2.
Or on
hard,
you could use
4 + 3 - 2 + 1.
Or on
monstrously hard,
you could use
(2 x 5 x 3) ÷ (1 + 4).
Actually, all of these would be acceptable ways to make 6 for someone playing on easy since you have to use
at least two numbers
on easy, but you can always use more if you want. However, you couldn’t simply use 2 + 4 on medium because it doesn’t use at least three numbers, and you also couldn’t ever use 1 + 1 + 2 + 2 because it uses numbers more than once.
*

Once any player finds an equation that works for their difficulty level, they should
**shout “Adsumudi!”.**
Doing so pauses the game and gives that player a chance to prove that the math works. If it checks out, the player
**takes the card and keeps it.**
Everyone then continues playing with the next card on the top of the deck.

If a player’s math doesn’t check out, there’s no penalty. Play continues until someone gets it right. Or if all players agree that a given card is too hard, simply put it at the bottom of the deck and move on to the next card on top.

The first player to
**collect 5 cards wins!**
Or for a shorter game, play to 3!

Yes! Depending on what kind of mood your group is in, a few different ways to play are below. You can also find the variants specifically recommended for each game online in the
**Adsumudi classic instructions**,
**Adsumudi Fun Ones instructions**,

**
Collaborative
**

Instead of competing for each card, players can work together to find solutions. Simply choose easy, medium, hard, or monstrously hard, then see how many cards you can get through as a team!

**
Around the World
**

Similar to the Collaborative version, Around the World has players working together to find solutions to all difficulty levels on a given card before moving on. Start by finding the easy solution, then medium, then hard, then monstrously hard. Don’t give up and feel free to grab a hint if you need. It’ll be satisfying to get them all!

**
Minute to Win It
**

Give all players pencil and paper, flip over a card, and start a 1-minute timer (or longer if preferred). Before time runs out, all players write down as many easy, medium, hard, or monstrously hard equations as they can find. When time runs out, players share their answers and get 1 point per number used in a valid equation. For example, if the target is 10 and a player finds 2 × 5 and 20 − 8 − 2, she gets 2 points for the first equation and 3 points for the second. Whoever has the most points in a given round wins the card. After 3 or 5 rounds, whoever has the most cards wins!

**
Tip #1: Work backwards!
**

New players often try to make Adsumudi’s answer by randomly combining the other numbers until they find something that works. But that takes a long time! Instead, try to work backwards from Adsumudi’s answer. For example, let’s say you were looking for the monstrously hard solution to a card where Adsumudi’s answer is 15 and the other numbers are 13, 10, 2, 9, and 3. Here’s a smart way to do it:

First, pick any one of the five numbers, say 13, and realize that to get from 13 to 15, you’ll need a 2 (by doing 13 + 2). So now all you have to do is make a 2 from the remaining four numbers 10, 2, 9, and 3.

To do this, again pick one of those four numbers, say 10, and realize that to get to 2 from 10, you’ll need either a 5 (by doing 10 ÷ 5), a 12 (by doing 12 − 10), or an 8 (by doing 10 − 8). Let’s go with 5. So now all you have to do is make a 5 from the remaining three numbers 2, 9, and 3.

Keep going with this strategy and you’ll realize that 9 ÷ 3 + 2 is 5. So by working backwards we just found that our monstrous solution is 13 + (10 ÷ (9 ÷ 3 + 2))! Brilliant!

**
Tip #2: Make 1’s!
**

Ones are useful mathematical tools! Multiply anything by 1 and you’re left with the same thing. Add or subtract 1 from a number to get something else that’s close. So try making 1’s where you can by dividing a number by itself or subtracting two numbers that are one apart. For example, imagine a card where Adsumudi’s answer is 3 and the other numbers are 9, 6, 18, 4, and 14. You can easily make 3 on easy mode with 9 − 6. But monstrously hard seems, well, monstrously hard! That is, until you realize you can make a 1 with 18 ÷ (14 + 4). Then all you have to do is (9 − 6) × (18 ÷ (14 + 4)) and suddenly you’ve wow’ed all your friends!

**
Tip #3: Split the deck!
**

Each card displays 1, 2, or 3 white stars at top. These indicate the card’s general difficulty level, where 1 star is the easiest and 3 stars is the hardest. If desired, you can use these to split the deck up for players of different mathematical abilities.
