I'm here quite often for about 9 months and here is an honest review of the poker room.
The dealers and people working around the tables are all very professional and helpful. Happy hour between 3-6pm and 9-11pm is nice with cheaper drinks and food. 22oz beer is $5 and the food is absolutely tasty. The daily Liquid-Lunch from 11am-2pm is 15 dollars for a dish and a drink.
Rake on the 1/2/3 and 2/3/5 is 7(6+1) dollars per hand if there is a flop no matter the pot size.
Under the tab 'Cash Games' you can see what games are open and the list is very accurate. There is no Fixed limit or PLO/HiLo here.
The only thing that would be negative is that the wait list is sometimes really long. They also most nights have 5 tables of 2/3/5 and 5 tables of 1/2/3. Check on their webpage for the list and number of tables open.
The games are full of action on 2/3/5 NL and every other pot is over 100 dollars with each 5th pot being 300+. A lot of action at the tables with a lot of regulars that are not scared to put money in the pot. Also if the table agrees there is a bombpot of 20 dollars for every deal change each 40 min. Playing in Vegas a lot as well I would say the action at M8trix is better than at any Vegas casino at 2/5 level. The 1/2/3 level is tough. There are some good players at that level and people that plays here often think it is 'easier' at 2/3/5.
Bad beat jackpot that starts at 50k if losing with quad 4s using both cards for both players.
And if the casino is not of your liking there is another 24/7 casino right across the street.
