We built a simple game in which you have three lives and need to solve as many simple math tasks as possible:

https://scratch.mit.edu/projects/238646321/#player

You can first select whether you want to add, subtract, multiply or divide numbers:



After that, you need to press the arrow keys to select one out of four possible solutions in the middle for the green pair of balloons:



When you make a mistake or a balloon reaches the sawing blade in the middle, you lose a life.

Every ten points, you'll get to a new level with more balloons coming in and the game becoming harder.

Playing this game will let you become quick at basic math in a fun way. Let me know your feedback!

Nice program!
I hope you can make it better later!

Thanks! Any suggestions are welcome.

One thing which would be great is if the game could be run on a smartphone. I think once ported to Scratch 3.0 (which I would have done right away if you could save and publish projects there …), this could be realistic. What needs to be done for Scratch 3.0 is to replace the text engine by (hopefully) out of the box functionality of the new Scratch version, allow swipe gestures instead of arrows and then hopefully it can be packaged for Android / iOS.

Does smartphone support Scratch3? I'm not sure, if it is, I can try your project on my smartphone.:O

Scratch 2.0 uses Flash, which is not supported on modern smartphones. Scratch 3.0 will work with HTML5, so it should run in any browser including smartphones. The main problem currently is that you cannot save your progress in Scratch 3.0 projects, so it's only useful for a little testing and not for actually doing a project in it.

That said, I just imported the Scratch 2.0 project in the Scratch 3.0 editor on my smartphone (by clicking on the green 2.0 button on beta.scratch.mit.edu). The basic functionality seems to be there, but the width and height is far off what it should be in fullscreen mode. You only see a small fraction of the screen and it does not adapt to the smaller screen size correctly (which is a bit weird since the resolution is high enough).

Another issue I see in the 3.0 editor is that the text engine I used is no longer working and I do not see the promised feature to add support for text directly in the editor yet.

Oh! I forget that sorry.
