Guess my number - CS Unplugged

This is similar to the game of 20 questions, but it is about guessing a number with the strict rule that you can only answer whether the secret number is greater than or equal to a guessed number.

What you need

• At least 2 people
• A pen or pencil
• Two or three pieces of paper

Skills needed

• Comparing numbers up to 100

Key question

How quickly can you find an answer just by asking questions that have a yes or no answer?

Activity steps

I’ve written a secret number on this paper, and you need to work out what it is. It’s between 1 and 100. Each time you tell me a number, I’ll tell you if my number is greater than or equal to your one. I won’t tell you if it’s equal - but you’ll still be able to work out my number!

Write a number on some paper, and fold it over so it can’t be seen. It can be any number from 1 to 100; in the example below the parent happens to have chosen 52 as the secret number.

What number do you want to guess first?

Write a "greater than or equals" symbol followed by their guess. (In the example, the child has guessed 50.)

(Depending on the number)
My secret number is not greater than or equal to your guess.
or
My secret number is greater than or equal to your guess.

Write a tick or cross depending on whether it is greater than or equal. Since 52 (the secret number) is greater than or equal to the guess (50), the presenter has written a cross.
Do not tell them if they have guessed your number! They will need to work out when they have enough information to know the number, so this is different to traditional versions of games like "20 guesses". The best guessing strategy is to start by guessing 50 (which the child happened to do in this case), but it’s fine if the child wants to use another approach - let them work it out for themselves!

Which number do you want to guess next? Again, say one of these:
My secret number is not greater than or equal to your guess.
or
My secret number is greater than or equal to your guess.

In this case the child has guessed 75. The secret number isn’t greater than equal to 75, so the presenter has marked it with a cross.

This repeats until the child can guess the number.

In the example, the child happens to have named the secret number (52), but the presenter has only said that their guess is greater than or equal to the secret number.

As it happens, the child can deduce that the number must be 52 from the information available, since they found out earlier that it’s not greater than or equal to 53. It can take a bit of logic to work this out, but it’s always possible to narrow in on the number.

You can play this game a few times so that they can refine their strategy and develop their logical thinking to find the answer. After a while they may discover that it’s strategic to keep dividing the range in half.

Inside the computer

This activity touches on several key ideas in computing. One is that dividing big problems in half, then half again, and so on, makes them very small very quickly. With 100 possible values, only 7 questions are ever needed to narrow down to the secret value if you use the right strategy. In Arnold’s challenges students can experiment with guessing numbers from 1 to 1000 - it looks like it would be 10 times as hard, but it only needs three more questions! Every time the range doubles in size, you only need one more question to guess a number in the range. In fact, you could guess a number from 1 to a million using only 20 questions - it doesn’t take that long, although you might want to use a calculator to half the range each time. This approach to narrowing down towards a solution is behind some very fast computer algorithms.

Another idea in the activity is that you can achieve a lot with only "binary" yes/no decisions. You might think that you need to check if the final value is equal, but you can know for use only by using "greater than or equal". Decisions that have two outcomes (often referred to as true or false) are the basis of "Boolean logic", which is one of the key ideas used in the design of digital devices.

Guess the number

In this tutorial we will learn the basic components of Aimylogic that will be needed to create any bot. As a result, we will get a bot that guesses a random number and invites the user to guess it during the dialogue.

Behavior of the bot

Our conversational bot should guess a number randomly. Next, the user puts forward his guess. If his guess is wrong, then the bot must say whether the number guessed by the bot is greater or less and prompt the user to try again. And so on until the user guesses the number guessed by the bot. After that, you can offer to play again.

Examples of dialogue with this bot:

Creating a script

Go to app.aimylogic.com. Create a new account or log in to your account.

Click "Create a bot or call" to create a new script:

Give the script a name, select the Russian language and click Continue .

Let's develop a scenario

The bot works according to the scenario that you develop. You can control the specific behavior of the bot by making changes to the script.

1. Greeting

At the start, our bot should tell the user the rules of the game and offer to play. To add a greeting message

The start screen is the screen that is on the left and at the top. The bot will always start chatting from this screen.

To add a greeting, press Text .

This will create block Text . Let's write in it:

Hello!

Click Save to add this block.

We have a start screen with block Text , in which the message "Hi!".

2. How do I add a screen title?

For convenience, let's add a label to this screen - the name of the script.

To do this, click on the sign # in the top line of the screen

Enter the name of the screen:

welcome

And select color

Screen name added:

3. Go to next screen

For convenience, in order to further redirect to the screen with an offer to play, add a Transition block here, which will redirect to the next message.

Press + BLOCK and select block Transition

| More about block Transition read here.

4. Offer to play

Let's add an offer to play Guess the Number.

We need the bot to redirect to the offer to play after the greeting, for this we use the block Transition . To create a connection, click on the block itself Transition :

The block selection window will appear. Select Text

Let's write in it:

Let's play Guess the Number?

Let's call this screen:

play

5. Accept user response

Add block Intents to the "play" screen. This block accepts user input. Block Intents should be on all screens where you expect the user to write something.

Learn more about the Intents block.

Aimylogic already has ready-made intents created for your convenience. They contain popular phrases sorted by user intent.

| Read more about Ready Intents here.

Click Choose ready -made intent

Highlight ready -made intenses - Consent , Refusal and Farewell :

Press Select 9000

000

Let's add the "play" screen to the "Come on!" button.

Read more about buttons here.

Press + BUTTON , enter text:

Come on!

And press Enter, or click on an empty space on the screen.

6. Guess the number

To generate a random number, we need a third-party service that can generate a random number on request. Such a service can be the site random.org, which can generate truly random numbers and events. This site has an API with which our bot can get a random number. We can use this API with block HTTP request .

• Click on the intent Consent .

In this way, we will create a link from intent Consent and define what the bot will do when the user says "yes", "okay", "come on", "okay", etc.

• Select block HTTP request .

Let's format the question as follows:

https://www.random.org/integers/?num=1&min=1&max=100&col=1&base=10&format=plain&rnd=new

In this URL, we have indicated that we will return a random number from 1 to 100.

If you open this address in a browser, you will see that it simply returns some integer from one to one hundred. If we reload the page, a new random number will appear, just what we need.

Our bot should request this number and store it in some variable, with which it will then compare the user's response.

Variables are like boxes in which we put something, some information. For order, it is convenient to sign the boxes, so each variable has its own name.

In Aimylogic we write variables using $ followed by the variable name. Case matters - variables $number and $NUMBER are different variables.

| Read more about variables here.

• On the RESPONSE tab, click + . Copy and paste in the fields:

Variable name :

num

In field Value copy and paste:

parseInt($httpResponse)

What's going on here?

After the HTTP request , Aimylogic saves the response of the random.org service to the system variable $httpResponse . But the random.org service returns text, and we need an integer so that we can compare the user's number with it (string and number are different data types in Javascript). Therefore, we need to first convert the text response of the service to an integer. To do this, Javascript has a parseInt function, which we will use.

Let's pass the entire response from the service to the function parseInt - this is how we convert the string into a number. We then write that value to the variable we specified in the ?? and store it in the variable $num .

• Let's call this screen:

request

7. Now guess!

The bot received a random number. The bot should now display a message to the user that a number has been guessed and invite the user to guess the number.

• Click on option Completed successfully block HTTP request and create block Text . In it write:

I guessed a number from 1 to 100. Guess what!

• Let's call this screen:

guessed

• And add "guessed" block Transition :
to the screen

This is what we get:

8. Let's take user input

* $NUMBER *

$NUMBER is a system variable that accepts numbers. At the same time, numbers can be called both numbers - 1, 3, 99, and words - one, three, ninety-nine.

Asterisks mean that any words can be before and after $NUMBER . This way the bot will be able to understand if the user says something like "Probably five". The bot will get "five" out of there.

| For more information about asterisks and other ways to accept input in intents, see the article on template syntax.

• Then press SELECT READY INTENT and select ready intents - Agree , Reject , Greeting , Farewell .

Thus, we provide for different user reactions, and then tell the bot what to do in response to such replicas.

receiving input

Here's what we got:

We've moved block Intents to a separate screen to make it easier to redirect here in the future.

9. Checking the range of the number

We need to make sure the user entered a number that is not greater than 100 and not less than 1.

• Click on the intent * $NUMBER * and create block Conditions .

Block Conditions is used when you want to add non-linearities to the dialog. You can write a Javascript expression string to a condition string. Depending on the fulfillment of one or another condition, the bot goes to different screens. If the condition in block Condition is met (if it is "true"), then the bot translates according to the link from this expression. If none of the expressions are executed (they are all "false"), then the bot checks the expressions below. If none of the expressions is true, then the bot goes to else . Conditions are executed from top to bottom. This means that if the upper condition is met, the bot leaves the link from it and ignores the conditions below.

In block Conditions , you can specify several js expressions - several dialog branches. In our case, we will have three branches: when the number specified by the user is greater than 100, when it is less than 1. Well, and the third - when the number is not less than 1 and not more than 100, that is, else, which is added automatically.

Read more about block Conditions here.

Copy and insert the conditions :

$ Number> 100

Click + Condition and add another line:

$ Number <1 9000 9000

• Press Save .

• Let's name this screen:

range

Here's what we got:

• Move the screens for a compact display. To move the screen, point to the upper left corner of the screen and drag:

10. If the number is not in the range of

If the user has entered a number greater than 100 or less than 1, we need to issue a message to enter a number that falls within the range.

• Therefore, from the condition $NUMBER > 100 create block Text in which we write:

Name a number from 1 to 100!

• Let's call this screen:

name the number

• Link the condition $NUMBER < 1 (if the number is less than one) to the "say the number" screen. To link an existing screen to another screen, click on the circle and drag the arrow to the target screen:

• Add block Transition to the "say a number" screen and link it to the "receive input" screen:

This is what we got:

Thus, when the user calls the number "two hundred" or "zero", the bot will say "Name a number from 1 to 100!". Then, since the bot took the user to the intent screen, the bot will be able to accept the user's response again.

11. Testing

We can check that everything works as we intended. Of course, the script is not yet completely ready, but we can check that what we have developed works.

• Press Test . The test widget will open.

Right now we only have a branch that says the number is out of range. Therefore, we will call numbers greater than 100 and less than 1.

• Let's talk to the bot as follows:

If the test does not work as shown in the screenshot, please check the previous steps.

What if I made changes to the script, but everything is the same in testing?

| If you want to make changes to the script (add, delete or fix something, change links, etc.) and check how the new version of the script works, you must restart testing, that is, press STOP TEST and then press **Test again.

How to start the same dialogue from the start?

To start the session from the beginning, click on this icon:

Then the bot will start the dialogue from the start. ---12. If the number is in the range

If the number is less than 100 and greater than 1, then the expressions in our block Conditions will not be executed and the bot will go to else .

• From else create a new block Conditions , in which we write:

$num < $NUMBER

$num > $NUMBER

• Let's call this screen:

comparison with the guessed number

0056 $num using block HTTP request ) with the number that the user has guessed (this number is written in $NUMBER ).

This is what we got:

13. If the number is less than

• Click on line $num < $NUMBER and create block Text :

My number is less! Try again.

• Let's call this screen:

less than

• Let's add the block Transition to the "less" screen and link it to the "receive input" screen.

14. If the number is greater than

• From condition $num > $NUMBER create block Text :

My number is bigger! Try again.

• Let's call this screen:

more

• Add block 9 to the "more" screen0004 Transition and associate it with the "receiving input" screen.

15. If the number entered by the user is equal to the number guessed by the bot

If the user guessed correctly, then the number will be no more and no less, which means that the bot will go to else.

• Click on the else screen "comparison with the hidden number" and create a block Text :

Correct! I guessed $num!

• Let's call this block:

guessed right

16. Will we play again?

• Add "guessed" block Transition to the screen. From this block Transition create a new block Text :

Shall we play again?

• Let's call this screen:

will we play again?

17. Add ready-made intents to the "let's play again" screen Agree , Reject , Farewell .

Associate intent Consent with the request screen.

18. If the user no longer wants to play

• From intent Rejection screen "play again? * create block Text :

Well, bye!

• Let's call this screen:

farewell

• Linking the intent Farewell from the "play again?" with farewell screen:

• Associate the intent Failure of the "receiving input" screen with the "farewell" screen:

• Associate the intent Farewell of the "receiving input" screen with the "farewell" screen:

• Associate the "Refuse" intent of the "play" screen with the "farewell" screen:

• Associate the "Farewell" intent of the "play" screen with the "farewell" screen:

19. Unclear

We cannot predict all variations of what a user might write. To do this, on block Intents there is an option Any other phrase . Any other phrase is executed when the user wrote something that does not fall into any intent and does not correspond to any button.

• From option Any other phrase of the "let's play again" screen create a new block Text :

Something I didn't understand...

• Let's call this screen:

let's play? incomprehensible

• Let's add block Transition to the "let's play? incomprehensible" screen and link it to the "let's play again" screen.

• From option Any other phrase of the "play" screen create another new block Text *:

Now it was not clear ...

• Let's call this screen:

start? unclear

• Add block Transition to the "start? unclear" screen and link it to the "play" screen.

Now let's refine the variant Any other phrase on the "receiving input" screen. Here we are asking for a number, and Any other phrase can work if the user did not name a number, said something that does not contain a number.

• From Any other phrase of the "receiving input" screen create block Text :

I don't see a number in your answer...

• Let's call this screen:

no number

• Let's add block Transition to the "no number" screen and link it to the "name the number" screen.

20. Associate intent Agreement of the "accept input" screen with the "say a number" screen.

21. Add block Intents 9 to the farewell screen0005 , create an intent, copy and paste into it:

 Player1 - 1 attempt Player2 - 2 attempts, etc. 

 rand_num = random.choice(rand_num_list) attempts = 0 import random import pickle rand_num_list = [1, 2, 3, 4, 5] rand_num = random.choice(rand_num_list) attempts = 0 # uncomment these lines to create a file # file = open("highScores.txt", "wb") # file.close() answer = int(input("Guess the number: ")) if answer == rand_num: attempts += 1 print("Guessed") print(f'You took {attempts} tries') elif answer < rand_num: print("The number is too small") attempts += 1 elif answer > rand_num: print("The number is too big") attempts += 1 

 file = open("highScores.
