You would have to use some sort of cloud list engine to save the persons username to a list if the list doesn't already have their name in it. If the list has their name in it then the have already visited the project. You could probably use @leafinos cloud list engine which is one of the easier to use cloud lists.

You don't need hacked custom blocks to make a ‘cloud list’. Custom blocks can be useful but ‘hacked’ suggests they're doing something more than can be done just using Scratch normally. I've only had a quick look but I think @Leafino is just using normal custom blocks. You can either just remix their project or copy scripts or sprites via the backpack if you want to use their code although I'd always prefer to understand the code in my projects.

My cloud list project is here https://scratch.mit.edu/projects/22828152/ - not sure if it's any easier to understand.

Most projects that do this are going to have their own variables! If you don't want to add more variables to your project you need to work out how to create your own version with the variables you have or with minimal additions. If you can understand the code that shouldn't be a problem.

My version would actually suit your needs quite well since you could use it without the decode at all - only required if you actually want to display the list of names which it doesn't sound like you need. My finduser block looks for the encoded username in the cloud variable without decoding it and adding a new username to the list doesn't require the list to be decoded either. The finduser block can search through the variable quickly as each username has its encoded length recorded so if the next name is the wrong length it can skip forward to the next name in the list and check the length. So it only looks for a match when the encoded name is the right length.

You call, obviously, but the main thing is you CAN do this without hacked blocks, you just need to understand how encoding and decoding work.

A very simple way you could do this would be by having a cloud variable. Your script would look something like this:

when green flag clicked
set [☁ Played before? v] to [ ☁ Played before? ]
if <(☁ Played before?) = [ 0 ]> then
add bonus for being first time
   set [☁ Played before? v] to [ 1 ] 
end
if <(☁ Played before?) = [ 1 ]> then
    don't add bonus because they've played before
end

When the green flag is clicked the “☁ Played before?” variable is set to whatever it was last time the player played. If the player hasn't played before, it is automatically set to 0. So, the script then checks to see what the value of the “☁ Played before?” variable is. If it is a 0, then the player has never played before and gets the reward. Then the variabke is set to 1, which indicates that the project has been played before and the next time the project is played, the script will recognize it.

If the value of the “☁ Played before?” variable equals 1, then the player doesn't get the reward, and the game starts.

If you have any questions, please ask.

This appears to be based on a misunderstanding of how cloud variables work. If you have a cloud variable as described all players see the latest value of the cloud variable. So as soon as one person has played it will assume every future player has already run the project.
