In 2010, we started collecting blackjack data from the Las Vegas Strip and downtown. As the years passed, we added all locals casinos to the list. We collected the following information in 2024. Below are summaries of the blackjack variants found in each casino. More detailed information, including blackjack and table game rules and minimums, is available through our monthly subscription service.
These are all the blackjack variants we found over the years that are still in service. The differences between each game and standard blackjack are explained here, as well as where you can find it now or where it was played in the past.
This page is split into two sections. The blackjack variants currently found in Las Vegas casinos are listed below. You may find ones from the past that are no longer spread here.

Blackjack Frenzy
Elements of Super Fun 21 and Spanish 21 are combined in Blackjack Frenzy. Players may double down after hitting. There are bonuses for some special 21 hands. Blackjack pays 6:5.
Blackjack Frenzy is available at Sahara with a $15 minimum bet.
Blackjack Switch
Blackjack Switch was the most popular blackjack variant in Las Vegas through 2017, though Free Bet Blackjack passed it in 2018. The number of Blackjack Switch tables has since crashed, dropping from 33 tables in 2014 to just four today.
In Blackjack Switch, a player must make two bets. There is an option of switching a card from one hand to the other. Blackjack pays even money. The dealer pushes players still in the hand when a 22 is drawn.
Now, Blackjack Switch can be found at only four Las Vegas casinos. The minimum bet is typically $10 to $50.
Bonus Spin Blackjack
Bonus Spin Blackjack started out as an optional side bet at many casinos. The game is otherwise identical to a traditional blackjack game. In 2018, it appeared at Four Queens and Golden Nugget in a different form. It later popped up at Binion’s and Fremont. These games force players to make the $1 or $2 side bet. By our calculations, it is the worst blackjack game, giving the house one of the largest edges in the entire Las Vegas blackjack market.
The version at Fremont and Golden Nugget only pays 6:5. On a $10 bet, the typical minimum for this game at these casinos, I estimate the house edge to be 3.9 percent. Some $10 Bonus Spin Blackjack tables at Golden Nugget have a required $2 side bet. These tables have a house edge of 5.5 percent.
The Golden Nugget game has a $5 minimum bet plus $2 forced Bonus Spin side bet at its 6:5 Lucky Cat Blackjack tables. I computed the house edge to be 8.95%, worse than triple zero roulette.
The Four Queens and Binion’s tables pay 3:2 with signs proudly displaying this fact. However, I estimate the house edge on a $10 bet at this table to be 3.9 percent. It is the third-worst blackjack game in Las Vegas.
It is impossible for a casual visitor or blackjack player to know the house edge of the side bet. Our research shows that 23 percent is a good estimate because an ace does not push the side bet like it normally does. That is the number we used to determine the overall house edge in these games.
Double Down Madness
New York-New York deals a new variant called Double Down Madness. Players start with one card and may double down there or hit. Double down is permitted after hitting. Players may hit or double down again after a double down, except when the first dealt card is an ace. The dealer pushes the live player’s hands on 22. Splits are not permitted. The minimum bet is $10.
Double Up Blackjack
In Double Up Blackjack, players may double up on any hand that stands on two cards. This includes after splitting. To offset this, the house wins all live hands of 20 and under when making a 16. It may be a soft or hard 16.
On the Strip this game pays 6:5. Double Up Blackjack at Binion’s and Four Queens pays 3:2. The minimum bet ranges from $10 to $15.
- Binion’s
- Four Queens
- Horseshoe
- Paris
- Planet Hollywood
Face Up Blackjack
Golden Nugget introduced Face Up Blackjack in 2024. Both dealer cards are dealt face up. The game pays 6:5 on blackjack. The house wins all ties, including blackjack. Double down is only allowed on 10 and 11. Pairs may be split up to three times for four total hands. The minimum bet is $10 plus a required $2 Bonus Spin side bet.
Circus Circus dealt a similar game for years. It disappeared there in 2024.
Free Bet Blackjack
Free Bet Blackjack is the most popular variant in Las Vegas. It had over 100 installs in 2024. We first discovered the game in 2013, when it had 12 tables throughout all of Las Vegas. In 2018, it overtook Blackjack Switch as the most popular blackjack variant in Las Vegas.
The house pays for all doubles on 9, 10 and 11. All splits are free, except on ten-value cards. Doubling down after splitting is free on 9, 10, and 11, except on aces, which must stand. To offset these rules, the dealer pushes lives hands on 22.
There are two types of Free Bet Blackjack games in Las Vegas. Most pay 6:5. However, downtown and some off-strip casinos offer the game with a 3:2 payout on the casino floor. On the Strip, two casinos have it in the salon. Minimums range from $10 to $50.

Free Bonus Blackjack
Free Bonus Blackjack is like Free Bet. We found it at three Vegas area casinos. It pays 6:5 on a blackjack. Minimums range from $10 to $25.
- Fontainebleau
- Palms
- Sahara
Lucky Cat
Lucky Cat Blackjack plays like a normal game except when the dealer has 22. Four six-sided dice are rolled, with each die containing one cat and five blanks. The player wins based on the total number of cats rolled. If all blanks come, the player pushes.
There are 6:5 forced Bonus Spin side bet Lucky Cat Blackjack tables in the Golden Nugget party pit. We rank it as the worst blackjack game in Las Vegas. It has a $5 minimum flat bet and a mandatory $2 side bet. Four Queens had a standard 3:2 Lucky Cat game without a mandatory side bet. That table disappeared in 2023.
Most Liberal 21
Most Liberal 21 originated in the years of Jackie Gaughan’s ownership of Plaza and Las Vegas Club. These are the only two casinos where the game has ever been spread in its more than two decades on the market. The game is down to one table at Plaza. The minimum bet is usually $5 during the day and $10 at night.
The game originally had the most liberal rules, as its name declared, but the rules were changed in the 2000s to what they are today. A player can double down on two, three, or four cards. Split aces may be hit, doubled, or re-split. Players win on a six-card Charlie. Blackjack pays even money, except for suited blackjack, which pays 2:1. The house edge is 1.33%.
Spanish 21
Spanish 21 has made two comebacks in Las Vegas. In our first survey in 2011, there were six tables of Spanish 21. There were two at Cosmopolitan and Palazzo, as well as one each at Fitzgeralds and Venetian. The Fitzgeralds Spanish 21 game disappeared when it became The D in 2012. The other casinos dropped it over the next year.
Palazzo and Venetian brought the game back off and on until 2017. Venetian is the only Las Vegas casino left with Spanish 21. The minimum bet starts at $25.
Circus Circus added Spanish 21 in 2019 but removed it in 2020. In 2021, the new Virgin/Mohegan Sun Casino opened with Spanish 21. It had a $25 minimum bet there. The game has since left the casino floor there.
Spanish 21 uses eight 48-card decks. The tens are missing. The face cards remain. Players may double down on any number of cards. Surrender is available on any number of cards, as well as after a split or double-down. The player always wins blackjack, which pays 3:2. A player’s non-blackjack 21 always wins as well, with bonus wins for hands that include a 678 or 777, as well as for five or more cards (a Charlie). Split aces may be hit or doubled.
