A Free, Basic Die Roller

I was sitting down yesterday and for the four hundreth time whilst designing I thought to myself;

Damn, I need my d30 again!

But this time, rather than just accepting the 2 minute loss of fossicking about for it I decided to do something about it.  I wrote a Java program that allows me to roll dice and get an instant result.  It is a basic die roller that is quick and exceptionally low demand but terribly handy if I ever forget my dice or want to roll just one die for any particular reason.

The application running and for the sake of art, a bit of its actual running code in the background

I then put the call out to see if anyone else wanted it and I got at least one positive response so here it is.  The application can roll 1 to 40 of any of the following dice (and combinations of them of 40 multiplied by the number of dice involved): d3, d4, d5, d6, d7, d8, d10, d12, d14, d16, d20, d24, d30 and d100.  I chose this set of dice because it is the “Die Chain” for Dungeon Crawl Classics and that is what I have been designing in lately.

A double click on the incredibly stylish (not) icon should run it.  If not you may need to right click on it and set it to be able to be executed on a Windows or Mac machine as they will not like that it has not got a digital signature paid for with thousands of dollars.  Apparently my good nature does not allow me on the OS approved lists.

If you want this little app for yourself but say it does not have a d50 which you really need, leave a note in the comments and I will add it.  It is an easy job to do and can be done quickly, but please only do it if you have a game that uses it.  I do not want to have to add a d1 through to a d1000 because it does take some time!

Anyhow, I hope that some of you use it.  If you have any other feedback, leave it in the comments.  You can download the executable jar from here.  The file is virus free and very light on system requirements and will not try to sell you anything at all!  Please also note that the appearance may change depending on the operating system.  If the proportions are not right for a particular OS please let me know and I will try to adjust them so it can work OK across all platforms.  Keep rolling 🙂


  1. Doesn’t seem to be available.

    I guess I’ll have to stick to the ones on my phone and ipod.


    1. Thanks for pointing out the broken link – I have fixed it so grab it if you would like 🙂


      1. Is there the possibility for a “plug in the number of sides” die, or multiples thereof? The ability to roll 3d31 could be useful. Likewise if such settings could be saved, providing for a truly user-defined set of dice.


        1. I will work on the option this week and notify when it has been added.
