Bingo question

If you will attach your .story file here, it will be a lot easier for someone to give you an idea.

Certainly! I pulled one slide from my project so you can get the idea. Basically, once the learner stamps four blocks in a row (vertically, horizontally, or diagonally) it would be nice to have a "congratulations" or "bingo" message appear, but I'm not sure how to start building that aspect of the slide. 

None of the built-in quizzes do what you want, so I removed the freeform from the slide. It's easier to build a totally new interaction if you don't have automatic quiz features hanging around.

There was a combination of two methods in the slide, and they were fighting with each other. I made two slides, one for each method. I highly recommend using one or the other, so as not to confuse the learner.

The drag slide allows you to drag the stamp and drop it on a square. I gave the Selected state a new name, as an object with a Selected state switches back and forth between Normal and Selected if it is clicked.

The click slide allows you to click on any square and change it to Selected or Normal. I also set it to remove red line if a previously selected square is deselected.

Instead of showing the red lines, you can show a layer if you want. The audio had about 10 seconds of dead air at the end of it, If you click or drag a second square before it comes to the end, the second square doesn't have a sound. So i cropped it.

 I deleted this trigger.

The hover state automatically does this, so if you create a trigger to do the same thing, you can have conflicts, with pretty nasty results.

Any questions, just ask.

Wow, Walt! This is just perfect. I can't thank you enough for helping me out with this. 🙌
