Nov 16, 2021 - Hey guys, so im making a code which i will link below where you have to collect eggs, but i wanted to add something extra. So, every time you collect an egg, you get 1 point, but i wanted to add Golden Egg which would give you 5, but with only a 10% chance of spawning after collecting a previous egg. You will understand better if you play the game, if anyone can help me make that of send a screenshot.

Tysm, hope someone can help

Welcome, @Evan1 !

You could do something like this:

 ![arcade-screenshot](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/6/694ac733d41bfa9cae3c333365a8dd9d62188dee.png)

The `% chance` block is in the **Math** drawer in the toolbox.

I created two different kinds for the sprites, _Egg_ and _SuperEgg_. That way, you could handle them differently when needed. For example, since you want to assign different points to the sprites, you could use two different `on sprite overlap` event handlers.

Let us know if you need additional help.

On my phone it is the last block in the Math section. All the way at the bottom. You can also try searching for it with the search box at the top of the category list thing.

Hello @oofie1st it should just be the bottom block in the math section. Send a screenshot if you can’t find it
