I don't think there are stats for variants.
bughouse stats?

I have no idea what all is on the to-do list. I know I've made lots of suggestions. A few of the suggestions that have been made include things like the ability to see how the leaderboard of a live tournament looked at the end of every round, implementing bughouse tournaments, downloading a whole bunch of vote chess games as a single pgn file instead of needing to download them all individually, and more. All these enhancements, plus various bug fixes, need to be evaluated and prioritised, and they don't have five million developers. So sometimes things just take time.
But if you use the "make a suggestion" feature under the Help menu, it will tell them that something is important to you, and something requested by a lot of people is likely to be moved up the priority list.

I second @croskie and @MGleason -- We've asked, we're waiting, it takes time (depending on priorities).
But in all reason and rationale -- it's been a while ... even basic stats should follow existing stats. ZH is pretty standard. I can understand a delay to implementing Bug stats ... but even Bug stats could be implemented along the same lines.
Not being able to implement is like saying: "We didn't write this code to be extensible and copy/paste/modified for each of 1-min+1-sec ... and then customized each such that it is now a mess and impossible to accomplish" ... (admitting to extremely poor development practices) ... and every other condition (which obviously cannot be the case ... so ... what's the deal?).

Well, I'm not a developer (with chess.com, anyway), so I don't know what all is involved or what else is on the priority list. I know some things can't really be done until the old version of the site goes away; maybe this is one of them. And there are huge protests every time someone figures out that the old version of the site is going to go away, so they've been holding off on killing it for a long time.

That's hokey-pokey BS.
The new (v3) site was published, right?
What prohibits the new version from implementing the same old features (but, with the new version). When you plan a new version of software with significant changes, this is part of that process. (And, yes, sometimes you have to support legacy; but at some reasonable point legacy has to go to the background and then just simply die.)
It's not like people are asking for new features. (Well, we are, in some regards, as it pertains to supporting new features already presented to us.)
The stats thing on the other hand -- that's pretty standard. There's really no excuse for even basic stats being extended to the new (v3) interface. Whatever excuses, they're lame-duck. Or, more pointedly: EXCUSES.
If implementing stats for variants is somehow unable to be done because the old (v1 or v2) interface is still online ... explain how and why v3 has come online with primary functionality (excluding even basic stats; just basic software extensibility; maybe even some minor re-write, or copy/paste to accommodate).
More advanced stats, such as for Bug ... that's a different story, that's a bigger deal that might take (justifiable) time to implement (excusable).
But, the basic stuff we had before ... not a big deal to extend it to the new stuff we have now. (Maybe some minor exceptions, and maybe some copy/paste/modify code that should be cleaned-up later ... but, for the most part, trivial.)
Let me ask this: Why does the new (v3) interface have most (if not all of) the older, traditional stats from previous versions? (And, by extension, excluding Bug not being 1v1, why can't or shouldn't that be extended to new variants?)
The new v3 interface has stats for all of the same as v2. (Unless I'm missing something here.)

Well, I know Erik has talked about there being a lot of features they can't implement in v3 while v2 is around. I don't know what's involved in adding a new stats category, but it may be it's a lot harder to add it in v3 without breaking something in v2, and, without knowing the code, I don't think any of us can really be too confident that's not the case. What if v2 looks at the list of stats categories and would blow up if there are variants it doesn't recognise, and having two separate lists is a non-trivial task?
v3 initially came online in beta. As more features were added and bugs fixed, they have gradually emphasised v3 over v2. I think Erik would like to have killed v2 a year ago, but has been holding off because so many people protest the idea.
Again, I don't know why it's not been done yet, this is just my guess. But I wouldn't be surprised if we see a lot of these kinds of things get implemented pretty rapidly when v2 finally dies.

Many people are going to create "crazychess.com" to play in variants.
I do not believe that you can see statistics for free accounts here.

I understand everything my friend. But I do not see any statistics at all, I have the most simple account. I can not write in the chat of the tournament.

You mean this?

On a member page click on the "Stats" button up right, then you can select bughouse from the list on the middle, or from the list on the right (the button that is unclickable from the member page, is clickable from the stats page).
No stats page for crazyhouse tho.
Hi everybody
it would be nice to have statistics for bughouse too, like for normal chess... (statistics could be improved a lot by the way, just look at how good they are on lichess.org)
Also it would be not bad to have a leaderboard for bughouse (again, like for normal chess)... is it that difficult?
what do you think guys? is it possible?
