On January 26, 2000, Cynthia Jay-Brennan, a Las Vegas cocktail waitress, won $34.9 million after investing $27.00 on a Megabucks machine at the Desert Inn. Naturally, the casino set her up in one of its top suites and offered her champagne and caviar.8

Unfortunately, the Desert Inn suffered the fate of many of the older casinos in Las Vegas: it was imploded. Today, Wynn Las Vega and Encore Resort now sit on the land where Desert Inn once stood. If you’re superstitious, you might want to try the casino at Wynn or Encore.

Wynn Las Vegas is an iconic, curved high-rise on the Las Vegas Strip with 2,716 rooms ranging in size from 640 square feet to villas at 7,000 square feet. Together with the adjacent Encore Resort, the entire Wynn resort complex has a total of 4,750 rooms, making it the world’s sixth-largest hotel.9

Wynn Las Vegas has a 223,000-square-foot convention center, 76,000 square feet of retail space, a spa, a salon, a pool, and an 111,000-square-foot casino. If you like to golf, Wynn Resorts also has the only golf club on the Strip. The 18-hole, 7,193-yard, par-72 golf course was designed by world-famous architect Tom Fazio and resort owner Steve Wynn.

Encore Resort features a 2,034-room hotel that is ranked as one of the top 100 hotels in the world on the 2015 Gold List. Encore also has a 74,000-square-foot casino, 27,000 square feet of retail space, a spa and salon, five restaurants, seven bars, and a nightclub.

1. Excalibur

Back in March 2003, a 25-year-old software engineer from Las Angeles won $39.7 million after putting $100.00 in the Megabucks slot machine at Excalibur. The winner, who wished to remain anonymous, beat odds at the time of one in 16.7 million to take home the largest jackpot in Las Vegas history.10

Excalibur isn’t just a name—it’s a way of life. On the south end of the Las Vegas Strip, Excalibur is a Camelot-themed resort linked to neighbouring New York-New York and Tropicana resorts by overhead pedestrian bridges.11

The hotel has 4,008 rooms, ranging from contemporary to guest suites. Amenities include shopping, four luxurious pools (including one for guests 18 years of age and older), a 13,000-square-foot spa, a fitness center, and, of course, the Canterbury Wedding Chapel.

The 100,000-square-foot gaming area consists of both table games and over 1,400 slot machines, including the ever-popular Megabucks progressive jackpot slot machine. The casino also has a poker room, keno, and pari-mutuel betting.12
