There have been a few games that have come and gone over the years. Invariably, these have been good games with low house edges and, consequently, not profitable to the casinos. I wrote pages dedicated to them for the earlier version of this site which I subsequently removed when the games themselves were removed. They're all listed here.

Also archived are other pages which I've decided to either remove or combine with other pages.

Betfair zero-margin blackjack

The Betfair one hundred percent return blackjack game came as part of the four-game "Zero Lounge" suite, starting in around 2008 and discontinued in 2016 when Betfair stopped using the Playtech software platform which hosted the games. The unique characteristic of this game was the 2:1 pay for suited blackjacks and a five-card charlie. The basic strategy to achieve that optimal payout was quite a bit more complex than standard blackjack.

Betfair zero-margin roulette

With one number (zero) removed but all the payouts kept the same, this must surely have been the most player-friendly roulette game of all time, and it required no skill at all to play.

Betfair zero-margin baccarat

Another game which required no skill to play, the Betfair zero margin baccarat game achieved that high payout by reducing the commission paid on winning banker bets.

Betfair zero-margin videopoker

If the roulette and baccarat games required no skill whatsoever, this Jacks Or Better variant with the royal paying 976 rather than the usual 800 did require quite a lot of skill to achieve the optimum payout amount of exactly one hundred percent - the much larger jackpot necessitated quite a few tweaks. However, simply playing standard JOB strategy achieved fully 99.98% return, so it's debateable whether or not it would have been worth the effort for the extra 0.02%.

Deuces Wild Full Pay

This game was offered by RTG casino "SciFi" in 2003. The theoretical player return is 100.67%, and I played about a hundred thousand hands at $5 a spin, hitting three royal flushes along the way. The full-pay version was removed a few months later.

Caribbean 21

Another RTG offering, this blackjack variant with low house edge was part of the standard game package for a few years. It was hit quite spectacularly successfully by one player, the so-called "Pirate Of Caribbean 21", who racked up $1,400,000 and subsequently had a big fight to claim even a portion of his winnings. The game was immediately removed, examined and returned to the software with a clean bill of health but an absurdly low $5 maximum bet. It was ultimately removed.

Boss Media single deck blackjack

Boss Media offered this game, with a return of 100.11%, for several years. I had a love / hate relationship with it myself. It was tested by blackjack expert Ken Smith, who concluded that the game was fair in spite of my occasional misgivings. It no longer exists.

Cryptologic single deck blackjack

In the early years Cryptologic offered a single deck game that came within a cat's whisker of a 100% percent return. alas, as with so many good games, it is no more.

I've archived this page not because it isn't relevant, but rather that it only lists one very generic game which doesn't seem to justify a place on the main menu.
