Secret Code – The 25 Most Original secret codes and ciphers to decipher

Secret codes and ciphers, we love them. That won't surprise you. Because let's face it, if you make an Escape Room, there must always be a puzzle with a good secret code. The trick is always to come up with a secret code that is not too easy and that also fits within the theme. Are you going to make a secret code for your children or for an escape room assignment? Then take a look at our list with the 25 best secrets.

Creating a mirroring secret code

This mirror secret code is always fun and not too difficult to create. Everyone has a mirror at home to decipher the text.
How do you create a mirroring text?

  • Open 'Word' on your computer
  • Create a text box on your worksheet with 'insert' – 'text box'.
  • Write the text you want in the text box.
  • Then click (with your right mouse button) on the text box and choose 'format text'.
  • Click on the pen icon and then you will adjust the data for 3D rotation.
  • Set X-rotation to 180 degrees.

Looking for a ready-made Escape Room for children?

Interactive Escape Room for groups of children up to 13 years old. Nice for in the classroom. With a lot of secret codes and ciphers.

Pigpen cipher secret code

You have probably seen this secret code. The funny thing is that it has a lot of different names. But, whatever it's called, this is how it works. Each letter is equivalent to a shape it is in. Sometimes as a box, sometimes with a dot. Are you going to get started with a secret code for children? Then you should not miss this one.

Creating a secret code with sentences without vowels

This secret code sounds very simple. But trust us, kids really enjoy trying to read sentences like this. You have to pay attention when you create it, because sometimes it is quite difficult to write a sentence without a vowel.

Tr t rslf n r cmptr, s wht t ss? 

Sign language as a secret code

For each letter there is a gesture with your hands. It does take some practice to learn this. But it also makes it very special to be able to communicate like this.

If you are going to use it as a game, for example, hang the explanation of the different gestures with the letters somewhere. In addition, make a video with one word or have it portrayed another.

Sign language as a secret code

Polybius square

The Polybius square is a coding in which letters and numbers are placed in a 5 by 5 table. This secret code is named after the Greek scholar Polybius, who invented this secret code as early as 200 BC.

The cipher works with coordinates. Which gives you the number first horizontally, then vertically. For example 23 is the letter M. Can you decipher what it says with the diagram below?

53, 43, 13, 45, 21, 42, 54, 34

Matoran alphabet

There are many secret codes with icons that represent letters. Don't ask us why, but we are always very charmed by this Matoran alphabet. Probably because you can use it so beautifully in all kinds of graphic applications. As a cipher, this alphabet is extremely suitable to be used as icons in a graphical application. For example , you can nicely process the circles in a motif and have a secret code deciphered.

Deciphering Emoji Secret Code for Kids

If we then go straight to the secret codes with symbols, then it’s great to do this with emojis. This is especially fun with children. You can send sentences to each other via WhatsApp in order to decipher this secret code.

Braille as a secret code

A great invention to be able to read: Braille! But also very nice to use as a secret code. You can display the dots in different ways to create your secret code. For example, lay down materials in Braille. Or put different colours of pushpin in Braille on a plate. Get creative!

Create code wheel

How to make your own code wheel to decipher a cipher? It really doesn't have to be that difficult. How does it work? Put an encryption somewhere, so you know how to decipher this cipher. Then you can drop a hidden message, which you can decipher by turning the code wheel.

The Pharaoh's treasure

Ready-made Escape Room for children.

Search for the Pharaoh's treasure, or you'll be locked up forever...

Create Morse code cipher

Morse code was invented as early as 1835, by how could it be otherwise, mister Samuel Morse .. Morse is a code that consists of long and short tones. We then put them down as (short) dots or as dashes. There are several morse generators on the internet to convert the code into sounds. But it is also nice to display the code, for example with lights. This can easily be done, for example, with a flashlight, with which you pass on codes. This way you can make your own creative secret code.

Create SMS code

For the slightly older ones among us, deciphering this cipher will be a breeze. Remember on your old Nokia when you had to type a simple text message. It gave you an RSI thumb! An SMS code works as follows: If you want an A, you click the 1 button once. If you want a B, you click the 1 button twice, etc. Do you know what it says here?

Secret code without spaces

How easily can you read a text without spaces?


If you occasionally hide a different capital letter in between, you can make a super fun secret code for children. Simple and funny.

Secret code that points to a book

You can create a code language that refers to a passage from a book. Refer to a book you have on your shelf or online. For example, put down the title followed by p18, r5, w3. Then you refer to the 18th page, line number 5 and you take the 3rd word. This way you can decipher a secret sentence with several words from the book.

Semaphore alphabet

If you are scouting or work in the shipping industry, then you are probably familiar with this semaphore alphabet. Normally you will see signals with two flags, which can be held in eight positions. In total there are many different possibilities, which are linked to a letter of the alphabet.

Secret code with wingdings font

We used to make a lot of secrets with this in class. Wingdings. It is a word font, where each letter and number represent a separate symbol. For example, you can even place entire texts and letters as a secret code. But be careful. It's just as easy to crack the computer again. Watch out for little brothers who want to read your secret diary. Do you know what it says here?

Secret code windings

From numbers to secret code letters

Another secret code that we all know from primary school. Each letter of the alphabet represents a number. Where a=1, b=2, c=3 etc. If you are going to set up a quest and are looking for a simple secret code to decipher, apply it. Known and successful with every child!

Convert coordinates to ciphers

Do you want to map out a route, with a text linked in cipher code below? Then it is fun to work with the coordinates of a map. Coordinates are often written in latitude and longitude. The latitude goes with N(orth) and S(outh) with a number of degrees between 0 and 90. The longitude is the position E(ast) and W(est). Here the degrees are between 0 and 180 degrees.

Google maps uses decimal degrees without N or S. If you click on a location, you can see what these decimals are. For example, put five of those numbers in a row as a secret code and you can take the first letters of the city as a secret code.

convert coordinates to ciphers

Create code language through a barcode

Barcodes are a super fun way to create a secret code. A barcode is of course also a code language in real life, but in a game or treasure hunt, for example, it is a fun way to decipher a secret code. You can display the barcodes as letters, or convert barcodes to Morse code. Where a thick stripe is a long tone and a thin stripe is a short tone.

Hieroglyphics as a secret code

Unbelievable! Hieroglyphs have been around since 3100 BC. They probably wouldn't have thought it would ever be used as a fun Escape room secret code. Are you going to make this secret code? Note that hieroglyphs use the same character for some letters in our alphabet. For example, the K and the C.

Vigenère figures

The Vigenère cipher is one of the most difficult codes to decipher. Crypto analysts love this type of ciphers. It works like an encryption, where a secret key word is converted using another (clear) text. This conversion is done in a large table with the alphabet both horizontally and vertically. We will show here a Vigenère example cipher.

You have the 'clear text'. This is actually the outcome of your Vigenère code. We have chosen 'Look in the drawer' here. You shade these letters in the left vertical part. You also have a keyword. In our case 'games'. These letters are in red in the horizontal part. And the secret text, is what comes out. Making the code works like this: First find the L on the left and combine it with the G of games. You get that the R. Continue in this way until you have converted all the letters. Where you use the keyword as often as necessary. Pretty complicated secret huh...

Music notes secret code

Are you going to make a secret code with a group of music lovers? Then you should not miss this one. Musical notes basically go from A to G, but you can of course vary this. Or have missing letters entered in a sentence that does occur with A to G. It takes some creativity, but it's a super fun way to come up with a secret code.

Crack code tap

With the tap code, the letters of the alphabet are in a table, just like with the Polybius square. You can find out the letters by listening or watching how many taps, or 'ticks' there are. In addition, the number of ticks of the vertical row is added first and then the ticks of the horizontal row.

How to make a Caesar code?

The cipher named after Julius Caesar is still widely used. You can also see it under the term ROT. You give a pre-encryption for how much the alphabet changes place. For example ROT3, then the alphabet moves three places. Then A->D, B->E etc. A super old secret code, but still fun and simple to make.

Runic alphabet

This alphabet has also been used as a cipher for a long time. Because they are such angular shapes, it is ideal for scratching into something. If you are going on a quest in the forest, scratch a hidden code in a trunk (which is on the ground!) to decipher.

Secret code runic alphabet

HTML colour codes as secret code

Did you know that every colour has its own codes? For example, a colour consists of an RGB code, for example, the blue of these letters has the code #0f72d6 . Want to create a secret code language? Or use a safe code for an Escape Room? Then you can create a colour secret code. For example, use every first letter from a colour code and make a word with it. Do you want to create a secret code with the colour codes? Then make the colour codes here .

Which secret code are you going to make?

Have you become really excited about all those secrets? We are of course very curious how you have used them. Will you let us know? Do you want more tips on how to use these secrets, for example, when making your own escape room?

The best games and activities for the last day of school

The last day of school: For many children and teachers one of the most special days of the year. 

Last day of school

All the work has been done, you are going to have one more great day and then you won't see each other for six weeks. So this last day of school has to be extra special, right? A day full of entertainment, being together, fun activities at school and of course games. We have put together some inspiration for you. Whether you have a last day of school with pre-schoolers or a last day of school for the upper classes. There is something for everyone. 

Since we are a game site, we think that a great game on the last day of school should not be missing. So which game is suitable for which group? And what is the best way to play such a game on the last day of school? And finally, we have some other activities that should not be missed on your last day of school. 

Games for last day of school for year 4 to 6 

For the age group 9 to 12 years, there are many fun games to do during the last day of school. Here we show you two of our games: 

Escape room last day of school 

Many classes have already played them. The children's escape rooms from Playgroupgame. Of course you are not really going to escape from the classroom. These are games that you print out and prepare and then you can play them in different groups. Actually you can play it as often as you like. As long as it is with different groups of children each time, otherwise they know the solution. Make it a competition, for example, to see which group of your class or school is the first to 'escape'. On average it takes an hour per group. 

The materials can be set out in the classroom or a gym, for example; the rest of the game is interactive. It will be handy if one of the groups can bring a mobile phone that day. If you don't want to, you can also play the game without a phone. Many schools indicate that they laminate the materials, so that it can be played more often by several groups.

Games for last day of school for preschool and year 1 and 2

For the really young children at school, the tension curve is not very big. For the last day of school they are happy with a nice course of games.  

For the children under six (preschool) these are fun activities for the last day of school: 

  • Bingo
    No matter what form you play, bingo is always a fun game for children. For preschool children you can make a bingo game with cards in the theme of holidays, for example. A great last-day-of-school game for pre-schoolers.
  • Cleaning together
    At the end of the year, the classroom needs a good clean. But how nice it is to clean it with the children themselves. For example, all the Lego can be washed in a bowl of water. Another group can clean the tables with wipes, etc. Be careful because a cleaning action can also make the classroom an even bigger mess...
  • Toy Day
    It is almost a tradition on every last day of school. But toddlers just love playing with their friends with their own toys. Want to make it extra fun? Buy something small for everyone at, for example, Action, so that they have a present to play with at the same time.
  • Create a scavenger hunt
    Go outside with your group and set out a fun treasure hunt. For toddlers, you don't have to go far at all, because you also want everyone to stick together a bit. A small tour is enough on such a last day of school. Need inspiration? Read our blog with "The 22 best ideas for an outdoor treasure hunt for kids"

Farewell song for the summer holidays 

The tradition is that you end the year singing loudly with the whole school. In our schoolyard, it is always a celebration to hear all the children singing at the same time. You have six weeks off, but the first few weeks you will surely still have the songs the children sing in your head. Looking for fun songs to sing on the last day of school? These are always a favourite: 

  • End of school song (covid -19 year)
  • Song: Celebrate a great school year

Last day of school poem

As a teacher you get a lot of presents from children on the last day of school. Enough chocolate to get you through the summer! But how nice it is to give the children from your class something themselves. We have put together some last-day-of-school poems for you for inspiration: 

The best last day of school games and activities

Scavenger hunt around school

We have already written a blog about it once; "20 ideas to organise a Scavenger Hunt". In fact, we have a free E-Book on that page, which you can download.

How fun is it to have all the children from the school in groups, accompanied by parents, taking a small tour of the neighbourhood with a scavenger hunt. Of course, one of the teachers (or someone from the parents' committee) will have to set out a route. Keep  especially the safety of the children in mind. So no routes where there is a lot of traffic. And also keep the age of the children and the difficulty in mind. It should be suitable for all ages at primary school.

We have therefore created 2 ready-made Scavenger hunts. One is suitable for 4-7 year olds and one is suitable for 7-10 year olds. The upper grades often find a scavenger hunt less interesting. So if you don't feel like spending a huge amount of preparation time to come up with a game on the last day of school, we have already made these 2 scavenger hunts for you.

Quest - Where's my dog
Quest - School Burglary

All you have to do is set out a route at your own location and put up our material there. The last school will be a big party.

Swinging out, jumping out, slipping... 

When the children actually leave, make it a spectacle by waving them off. For example, let all the children jump out of the school via a trampoline. Or put a bench from the gym against the window where everyone can slide out. 

Don't have that option in your school building? Then this will always work on your last day of school: Turn the music up loudly. Put each child in pairs with their hands against each other. And let them run through each class as a pendulum. Start with the toddlers and end with the year six. 

Convenient for schools 

Complete package for schools: For older children in the final years of primary school. Buy 2 escape room games and you get the second game with a 25% discount. And super handy for schools, you only have to print these games once. If you then laminate them, you already have a fun activity ready for next year's summer party/teacher's day or whatever. You may reuse these games within your own school. 

Ending the last day of school with colleagues 

And then... it's time for a rest. And... a cosy ending with your school colleagues. Would you like to play another fun game with your colleagues on the last day of school? Then check out our games for adults. 

We hope we have given you enough ideas. We are looking forward to your response. Will you let us know below? 

Have a nice holiday!
