Check out this Great Tool: Mathammer 40K

Matt Toner is the creator of this very cool site and app, that allows you to easily calculate the odds of an action in 40K.

Knowing the rough odds of a certain action in 40K is a really powerful tool. Most of the bet players can either run the numbers in their heads, or memorize odds to allow them to make smart decisions about what they should or should not do while playing. For those less mathematically inclined, this tool allows you to run the numbers on your phone or at home with ease!

Matt and I played at the SiS4 last weekend, and he is an excellent general with a really cool Necron army. Give the tool a look!

    Hmm… I’m not sure if I would call this a great app, and I would be embarrassed charging money for something that reeks of laziness like this (IE, it doesn’t take much effort to add an option to account for poisoned weapons). All of the customer reviews seem to comment on things missing from it. Also, the fact that update notices are posted as five star reviews, not cool. I think an app like this is cool, and most definitely has uses, but this one is shitty. Would not buy for a dollar.

    In case it was not clear from the rest of the comment, the site is free, the app costs money, despite complaints of inaccurate percentages and missing rules.

    Wow sharkticon, that’s a bit scathing first thing in the morning, but I’ll address your points.

    1) Conceptually poison is easy (wound on 4+ for example, reroll wounds if strength is greater or equal to toughness), but it actually ends up adding a lot of lines of code. Further, anyone familiar with the game can just set weapon strength and toughness equal to each other to get the same effect, with the option to check the box that lets you reroll wounds. Another consideration was things like Agonizers and Witchblades which wound on a certain value but are not poisoned weapons – affecting whether a reroll to wound exists. Lastly, I didn’t want to shrink down the slidebars too much on the app, which meant I had to choose the best six checkboxes to include, which I didn’t feel included poison, since the effects are easily attainable by varying strength and toughness. In the end, I decided that it would be best to leave off a “poison” checkbox.

    2) Update notices are not posted as 5 star reviews. Not quite sure if this can be done, and I’m not sure why you think it was done.

    3) I have no idea how “josh” determined that the stats were wrong. He never contacted me. I can guarantee that all the math is correct.

    4) Yes, the site is free to use. The app costs 99 cents so I wouldn’t have to support costs by running an ad bar in the app. Ad bars in apps bother me.

    In all, I hope that people try both out. I like the site, and I like thinking through the mathhammer, especially when considering armies I’m not familiar with. I’m grateful to Frontline Gaming (and Reece in particular) to mentioning my site here. Please check it out and let me know what you think.

    I run all of my numbers in my head. Plus, I’d imagine it would be a bit difficult to pull your phone out before every shot/charge. If you want an amazing tool for math hammer that’s for long term use, check out 40k Metrics, by Nikephoros. It’s not the end-all-be-all, but it’s a great way to benchmark lists against each other to find out if they’ll be effective or not.

    Here’s the main article-
    Here’s his FAQ for the system-
    And here are some really quick and useful rundowns on specific units-

      40k metrics is really interesting stuff. Thanks for pointing it out. If you are looking to create your own data tables to measure your units’ effectiveness, would help you calculate everything you need. The only exception would be if you want to find “effectiveness per points” to compare different units in a codex (hive guard, harpy, and tyrranofex were his example). But you could use the site to generate raw data then your handheld calculator to do the final effectiveness per points calculation.

        Very true! The actual math of it can be a large workload. However, I’ve not been able to get your site to work in IE9. Is it coded for other browsers?

        • Matt Toner June 11, 2012 8:34 am #

          Very weird. I’ll work on that right away. I typically use Chrome, but it should work for older versions of IE. Thanks for the heads up!

    Sweet. I wont even have to bring dice anymore, right?

      That’s the goal!

      Actually, I envision the website as more of an army building tool rather than something you’d use during a game. I think of the app as something you can check during a game or play with on your commute.

      For instance, did you know that twin linked psibolt assault cannons have a 13.2% chance to destroy a Monolith in one turn of shooting?

    Don’t know if anyone is still looking at this post – but I just wanted to let people know that and the Mathhammer40k droid app are now completely 6th edition compliant! Come check them out!
