also be drivenby "random" programming -- with a suggestion that this
is true in NYstate."

I think you meant to say that Washington and New York are "pulltab"
equivalent (or something similar that is not a random deal). West
Virginia is a random deal. (Delaware as well is a random deal.)
Thanks for the correction -- I'm increasingly addled when I write off
the top of my head 
Just to correct myself:
-- Washington State Indian Casino video poker is VLT based in the
traditional sense -- results are centrally determined and distributed
to the machine in advance of the deal akin to a pull tab.
-- West Virginia games are traditional fair and randomly dealt games
-- what you see is what you get in terms of the paytable. However,
because the state restricts game payout to 95%, and makes no allowance
for the fact that player skill (or lack thereof) will typically result
in a vp machine paying out less than optimum strategy, you won't see
decent paytables in WV.
-- Delaware machines are reported to be fair and the VLT designation
of these machines reflects only that they are operated under state
lottery authority. State statute does stipulate a max payout of 95%,
but provides for the Lottery Director to approve higher payouts as an
exception. I have no experience with the machines in DE.
I'd be most comfortable with gaming in DE were IGT machines in use --
ultimately there is no mistaking an IGT LV compliant machine from an
IGT VLT -- the VLT's use a "genie" to correct a player's hold when
it's not consistent with the pre-determined win. (WA state casinos
use a "match card" mechanism to accomplish the same thing). If other
equipment is in use I'd be cautious.
-- There appears to be little question that New York State machines
are not randomly dealt. In fact, an article on the Albany Law School
website discusses this, writing "If you make a playing decision that
costs you the payoff you should have gotten, the lantern or fairy or
genie appears to improve your hand and correct your result." I find
it interesting, however, that discussion of NY machines here hasn't
suggested this is the case. (See:
