The Mazagan Resort near Casablanca, Morocco celebrated their 5th year anniversary this weekend. From 8pm until 10pm Friday, Saturday and Sunday they offered all kind of promos on their table games based on the number 5. Some were slightly interesting: 500 dhs (about 55$) if you have a set of 5s at UTH, a stack of 20 chips if you bet and won the number 5 at roulette (pays 55 chips for the first chip you bet). However the most incredible one was at the blackjack table: they paid winning blackacks 5 times! What is the house edge with this rule? They still offered the same rules as usual (shuffling machine, S17, DAS, double any two, no resplit aces, surrender ). I am pretty sure it is negative under proper basic strategy.
