I like this variant!
There seemed to be a number of times when everyone would roll two unmatched siders (which puts them out for the round). The rules don't seem to have any explanation for what happens at this point (Rule Rulers, feel free to point out the exact rule I missed). I suppose the card could go under the deck and you start a new round. However, we decided to do the same thing as when no one can get a leaning jowler:
When everyone is out on a card, put the next card on top of the missed card. Whoever wins that card gets both.
The game can also drag a little during some of the harder cards. We discovered a fun solution somewhere online, which my wife has dubbed Going Hog Wild.
If no one gets a card after three rounds, it becomes a mad race to see who can get it first. Turns no longer matter.
You may need to do away with the unmatched siders = out rule here.
