Word Jumble || Scramble

You need a correct target and an incorrect target for each letter. As it currently is, you only have a correct target so you can only place the letters in the correct and it gets kicked out everywhere else.

You don't need to have a show layer trigger. What you need is change state of correct button to selected when objects are in the right targets. And change state of incorrect button to selected if objects are not in the right box.

That will make the right wrong selection. Then hit submit and the appropriate layer will show.

Also, you should title your buttons and objects so they make sense and easy to troubleshoot.

This is kind of how you should start the triggers. https://a.cl.ly/o0uG0mB7

Hope that helps.

You may want to look at the options for drag drop convert to freeform because you would need fewer triggers to evaluate correct/incorrect states and then manually create a trigger for the duplicate letters.

I played around with the convert the freeform drag and drop and it seems to work with just two triggers.

No problem. These are always good brain teasers and there's always something to learn and multiple ways to do things.
