Welcome

Interesting app. To get specific advice, please share your code.

What does 'lock buttons' mean to you ? Create logic to prevent access to a button until certain things happen perhaps. We don't know what. To control the logic, use 'conditional statements' ... see Programming Your App to Make Decisions for example code.

To create a screen that looks like what you displayed, you either need 14 buttons with images or 14 clickable images or 14 Image Sprites on a Canvas or something similar method to create the display and display what happens.. If a level has been achieved, the image in a 'button' should change if you use buttons (requires switching between two images)..

To disable a button (make it non-responsive); use the set Button.Enabled to false; to enable the button, set Button.Enabled to true might be what you are asking about. Doing that with Enabled will 'lock' or 'unlock' buttons in your graphic display. To make your game work, provide the logic to determine when a button should be locked or unlocked (if ... then ... else type logic).

If you want specific advice, share your Project or an example and explain what you need to do.

There is no tutorial that explains how to build your game.

There is an alternative to the method I mentioned earlier. Instead of just disabling the buttons you could use if/else statements S oeven if the person tries to open the they will receive a notifier message

Here are the blocks I told you about. Use Either of the buttons to make it. Sorry, for you will have to take the time to separate the blocks for doing it.
