Is there any specific reason why you can't split Aces at the blackjack table?

Yes.

Yes.

I have been able to split any other similar cards besides aces, even AFTER I have split the initial pair.

Here's a screenshot:

Some house rules don't allow splitting of aces (though these are ones that provide the larger/largest house edges - some further info http://www.qfit.com/blackjack-rules-split.htm), so possible that this has been/was included in the coding for blackjack in the MR casinos.

I know at one point it was coded so that aces may be split, but only one time.

I blame Kates for this.

I personally blame Striphe for everything casino related!

More importantly, who thought we'd ever hear Matterhorn complain about being stuck on a soft 12, ehhh.

I just hate when I show the ladies all I can come up with is 2.

Frown face.

lol I just wish I could win some cash every now and then

I am assuming that this is due to house rules (although some clarification would be appreciated), however in my experience (in the UK at least) most houses allow you to split aces but only allow one draw card on each...

Yes, I have never been able to split them either :(

Just wondering, will this be changed?

or is it a specific "house rule" that MR casinos will implement by default?

Why would it be changed?

It's a common rule often employed by casinos to increase the house edge slightly. I'm sure the casino owners on MR, if given the choice, would certainly choose to keep the house rules as are (or even push them more in the houses favour if they could).
