No-Reveal Blackjack: standard casino rules, dealer hits soft 17, blackjacks pay 3:2. The dealer never reveals her down card.
Single-Reveal Blackjack: Same rules as No-Reveal Blackjack, but the dealer actually reveals the down card only to the player sitting at third base.
No-Reveal Craps: 3x odds. Shooter throws 1 die and the banker announces the result of the other die shown on a display only he can see.
Dealer-Reveal Craps: Same as No-Reveal Craps, but the dealers verify the number announced by the banker.
Electronic Voting: Election rules are set and enforced by a bureaucrat who also serves as final arbiter. Votes are entered on and counted by a computer running proprietary software.
Secret-Ballot Voting: Same as electronic voting, but votes are written (though not attributable to any voter). Ballots are hand-counted in rooms observable only by apparatchiks chosen by the major political parties.
