It is a nice UX, but with a fatal flaw: Tiles are supposed to be free when there is a side free, but you instead have it coded to be free when the top or bottom is free. Your app, your rules, so if you intended to do that, cool. It is just a fundamental divergence from how other implementations do it.

If you rotate it so the board looks like the traditional solitaire layout, the direction of free tiles is horizontal as it's supposed to be. But then the images on the tiles are rotated 90 degrees. Either way you look at it, something is non-standard.
The other thing is that this implementation doesn't seem to support overlapping tiles, which is kind of important. For instance, the topmost tile should overlap and block all four tiles under it.

Thank you for the insight! I think rotating the tile images is key. Since I’m using CSS Grid for positioning, there are some limitations around overlap like the one you mentioned, but it should be solvable. I’ll keep working on it to bring it closer to the standard behavior.

Two games in a row now I have gotten to a point where the last two pieces are ontop of eachother. I think this is perfectly fine, but seems to happen a little too often. Or I was just very unlucky.
Otherwise it's a sweet game!

Thank you! I'm going to review that. In the meantime I've added Undo/Redo options so you can backtrack your steps.

Thanks for mentioning this. I played a little bit and I felt like it was the opposite of what I'd remembered. I do like that the inaccessible tiles are faded somewhat so that I don't inadvertently try to match them.

> Tiles are supposed to be free when there is a side free
No.
According to wikipedia[1]: "A tile is said to be open or exposed if it can be moved either left or right without disturbing other tiles.". Also look at the photo in the wikipedia article[2]. This implementation looks correct to me.
A "free side" means being exposed on the left or right, matching your Wikipedia quote. On the other hand, OP's implementation checks if it can be moved up or down.

Coding + Mahjong related story:
Back in college, while majoring in CS, I had a rough time dealing with semicolons, typos, missed characters while coding.
I thought to myself "I wonder if playing Mahjong in the Windows games would help me get better at scanning code and finding these types of errors". So I tried it and, lo and behold, it did.
Also, in this day and age of LLMs writing a lot of the code, scanning for missing semicolons in code sounds like "I was great at fixing telegraphs!"

This is lovely! Can I suggest make sure that the board is solveable?
uean 20 hours ago [-]
This is part of the game. Many games will not be solvable.

I think this is a good example of what CSS can do and probably was not easy to make but I will likely stick with Mahjong that comes with most Linux distributions as they follow rules that people I may end up playing against would know and they have many layouts. I could see this being applied to other things however such as games that require building or repairing something. Or something similar to Minecraft?
Which makes me wonder which ruleset would be the easiest to implement. Probably MCR or HK, riichi has too many edge cases and sepcial rules and yakus.

Riichi is the fun one, where skill weights over luck.
haunter 1 days ago [-]
I also prefer riichi. Furiten is such a game changer, all other rulesets feel a bit less after that
whateveracct 1 days ago [-]
Riichi is a good candidate for a video game due to all the specific rules. It has a lot of room for QoL. I have an app on my phone [1] that has made it fun to play and learn thanks to the guidance it has with the rules
Well the other options are the gooner gacha games like Mahjong Soul and Riichi City lol
Personally I play on Mahjong Soul because apart from Tenhou that has the most populated PvP with enough players in each rank + it's a butter smooth experience with all the small features. And I love the special modes like Battle of Asura

I've been looking for a free one with really good helper UI to keep track of all the rules.
haunter 1 days ago [-]
Helper UI per se won't exist because there are so many little things.
Personally I'd say Mahjong Soul is the best riichi client out there, that's where I play https://mahjongsoul.yo-star.com/ Extremely streamlined, good QoL features like tile highlighting (dora too), showing waits and options when you are tenpai, custom lobbies (so you can play with friends), and a pretty robust online ranked system. There is a good tutorial too. The big downside is the gacha system which is purely cosmetic and doesn't affect gameplay at all but it can be a turn off for some people.

Riichi is the most fun one, in my opinion, but I would not go so far as to say "skill weights over luck". The absolute best Riichi players win less than 25% of hands.

If I click fast enough on mobile it starts trying to select/highlight text, should be able to prevent that with CSS too. I find this is somehow a common issue that separates a lot of PWAs from real apps, the browser text engine is still lurking there in the background trying to recall us all to the glory days of hypermedia
koolala 1 days ago [-]
Mahjong tiles are in Unicode so they could convert that functionality into accessibility information.
There are some super weird bugs, sometimes only one of the two pieces are removed and sometimes the field goes blank? Also on every move the faves change?! iOS here. And yeah, no majiang, but still super cool! Nostalgic vibes waiting for my fries and playing the Photo Play touch screen gambling machine (after unlocking it by tapping the words photo and play on the logo with two different fingers and entering the code)

This is pretty cool. I like the look and the gameplay. Though playing on mobile, some of the roatation gestures caused the page to refesh on me a couple of times since they triggered the browser's "drag down to refresh" interaction

DuncanCoffee 1 days ago [-]
Nice! Wish the supported rotation was bigger, maybe +- 90 instead of only 90 deg?
omoikane 1 days ago [-]
Maybe it was done this way so that they don't have to sort the tiles by depth?

Would it just be the opposite depth of the current sorting once you pass 180 degrees?

There's some CSS properties specifically for doing 3D, yeah. You use perspective and perspective-origin to create the view frustum, and then CSS transforms to place your elements in 3D space.

This is Mahjong Solitaire - It's completely different to actual Mahjong. It's a completely different game that uses Mahjong tiles.

Beautifully made though.
What I liked about the first one I saw in the 80s was the cascading shadows. Admittedly they were more important for 2d version
