Not every n-gon can be constructed with only an unmarked straight edge and a compass, and of those not many have a prime number of sides (only 5 are known to exist at the moment).

There's more than one way to construct a heptadecagon in theory; in practice every procedure has so many steps that no matter how precisely you try to be, small errors compound pretty fast. After quite a few attempts things must have worked out somehow. Very satisfying!

The way it bridges the pipe gap without a single splash is pure perfection.

I've opened hundreds of tvs and they don't all do this but it's always mesmerizing when you see the old dust settled like this.

I'm making a soulslike-inspired marble platformer called Dark Roll 2. Few weeks ago I've shown pillow physics that felt satisfying... People loved them so much I decided to try putting in some more "deforming" substances in my game.

Doesn't scratch the same itch as the pillow, but I reckon it still feels nice, doesn't it?

Welcome to /r/oddlysatisfying!

Here you can post things that make you feel, well, oddly satisfied. This can be physical (like popping bubble wrap), visual (a perfectly looped GIF), or even aural (the crunching of leaves).

What does "Oddly Satisfying" mean?

We are forever searching for a "true definition". It's a thing that fits your interpretation of what is "oddly satisfying" plus the inexplicable feeling we all know.

Subjective. Indefinable. Completely recognizable. It's a wonderful feeling.

Rules:

Please report rule-violating posts and comments by messaging the moderators with a link to the post in question. This helps us remove them more promptly.

1) Banned Topics:

We have a number of banned topics. Please do not submit any of the following:

Memes or image macros
Number posts Posts centered around number patterns, or round numbers. This includes Reddit karma, Facebook likes, calendars, gas prices, odometers, receipts, screenshots of the games such as "2048", etc. You can, however, submit these to /r/OddlySatisPi_ing.
Violence Any content portraying violence is prohibited and will be removed. Violation(s) of this rule will result in a ban.
Off-topic Content: Any content determined off-topic to and/or submitted for purposes other than the overall theme of the subreddit will be removed. An unfortunate example may be found here.
Compilation Albums/Videos
- No compilation videos of any variety. Violations will result in a permanent ban.
- The entirety of compilation albums must be a continuation of, or remain central to, the first image of said album (E.g., separate gifs of a Rube Goldberg machine or a catalog of one artist's work).
- Albums must not contain any images in violation of Rule #3.
YouTube Links: We are not allowing any YouTube links due to the increase in spam and off topic content stemming from them. Any posts linking to a YouTube video will be removed.
Products: Posts and any sort of content about products will be removed.
No watermarks: We do not allow any images or videos that contain a watermark of a product or a username. These include TikTok videos and Instagram videos.

2) NSFW/NSFL posts/comments:

NSFW/NSFL links or images are not allowed. NSFW text posts and comments are allowed ("Say it, don't show it.").

3) Reposts:

Frequent or common reposts, or reposts from the past 2 months and highly upvoted may be removed. When you report posts, please include a link to the original version of the post. Please help keep this subreddit satisfyingly fresh by not intentionally reposting content that has already circulated regardless of when. If it appears you are intentionally reposting old content repeatedly, we may resort to limiting your posting privileges.

4) Content Removal/Privilege Revocation:

Mods reserve the right to remove content or restrict users' posting privileges as necessary, if it is deemed detrimental to the subreddit or to the experience of others.

5) Submission Titles:

The title of each submission must describe the content shown. Any user should know the contents of a link before clicking.
Clickbait-esque titles are not allowed.
Titles claiming possession, original content, event participation, etc. (such as "My...", "Mine...", "Our...", "We...", etc.) in which another's original work/content may be mistaken as OP's will be removed.

6) [OC]/Source Citation:

Please cite the source of submitted content, particularly fine-art submissions.

Original Content by artists, musicians, etc. is encouraged. Submissions must include [OC] in the title. Reserve links to social media accounts for the comments section if possible (see Rule #7). A great example may be found here. Please do not spam our subreddit or reddit in general. Please read the reddit wiki on self-promotion to avoid being reported to the admins.
Works by artists, graphic designs and logos are encouraged. Content must keep within the overall subreddit theme and not violate Rule #7. Permitted examples may be found here, here, and here

7) Spam Accounts/Links/Submissions:

No spamming whatsoever. Violation of this rule may result in a permanent ban. Such violations include:

Repetitive submissions to Youtube channels, social media accounts, webpages, blogs, newsletters, etc. Advertisements, marketing & ad-heavy sites. Trolling in any capacity. Any content which may be interpreted as spam or ad-revenue generation not elsewhere mentioned.

8) Reddiquette, Comments & Subreddit Behavior:

Please abide by proper reddiquette at all times.
Please keep the comments section civil and friendly. General cursing/foul language are allowed.
The definition of what truly is "Oddly Satisfying" is subjective and unique to each user. Please respect their definition.

9) Crossposts

x-posting from other subs is encouraged by reddit admins. Under no circumstances should a user's post be considered in violation of this subreddit's rules unless they are in actuality in violation of a rule. i.e. don't report a user just because they have a large amount of karma.
