Firewood Splitting Simulator | Hacker News

This simulates a person far more skilled than me.

I never had to adjust the chunk to get it to sit right, the maul hit exactly where I told it to, and it even stacked itself!


If this triggers your interest in IRL firewood splitting it’s a very meditative and satisfying yard job. Also great mild to moderate workout between the splitting and stacking, especially on a crisp Fall afternoon.


I have a lot of splitting to do right now, and you're welcome to it. I'll only charge a low nominal fee. But let me know before September, because that's when I usually go rent a hydraulic splitter from the local hardware store. Then I spend a very long day splitting so that I can return it the next day.

I've spent a lot of time splitting with a big maul, but for me it's harder that it looks. I've broken two mauls by striking to far and breaking it. And even with "soft" wood, I have stacks of green rounds that I couldn't split at all, the maul just bounces off. But I'm glad that you enjoy the process, I'd probably enjoy watching you work.


Good workout and satisfying, I totally agree. I actually really enjoy it.

But the long term effects on your joints, even if you think you have perfect technique, its better to just get a wood splitter. We can do a whole winters wood in less than a day now, with minimal effort.


Beautiful sim. Looks like red oak. As someone who has split a lot of wood, wish it could incorporate more of the struggles of splitting logs.

- missing your spot by 6” or more and creating a tiny shard that goes flying - the log you’re aiming at falling as you are in your backswing - getting your maul stuck halfway down the split


Yeah this needs pieces with knots, and having to swing at least 3 times before the initial split works. Very unrealistic, 3/10. Need some wedge + sledgehammer modes.

Also how do I simulate my shoulder and lower back hurting?


Very satisfying & simplistic. I also like the stacking, well done!

Funnily enough, I've been making a game with an extremely similar mechanic, only in low poly and with a focus on upgrades (both "real" and ridiculous DIY axes) and "drunk backyard dad" jokes. It's called Drunk Woodcutter and coming to Steam in Q4.


Nice sim, there's one thing missing though: splitting two sections at the same time. It do this all the time as it can almost double splitting speed when dealing with mid-size logs. Split the log in two halves, making sure to keep the halves close together. Rotate around the splitting block by about 60°, split again hitting both halves at the same time. Do this once more and you've split the log into 6 60° sections, a good size for stacking in the fireplace and also a good section size to be able to light a fire. I split between 5 m³ and 7 m³ of firewood per year which is enough to heat our house and cook our food, have been doing this for about 20 years now so I have some experience. The double-split is a good time saver.


That and the fact that you can rotate w/ left click as well. Turns out I naturally drag the mouse a little. So having rotate on right click only would be way less annoying, especially when combined with the momentum.
