I think any decent poker variant has to have a skill element BUT a large enough volatility that the fish return.

Here is my variant.

It's draw poker for high. One draw. Two blinds. Four betting rounds.

First betting round is pre-draw.
Second betting round is post-draw.
Third betting round is after every player simultaneously reveals two cards from their hand.
Fourth betting round is after every player simultaneously reveals one card from their hand.

Show-down, each player reveals their remaining two "hole cards".

Betting is 1/1/2/2 as in Hold 'Em.

I suppose you could play this Pot-Limit and/or as a lowball game as well.
