That's a great inquiry. Several establishments eliminated their buffets during the pandemic shutdown. Here’s a compilation of those that remain operational, but keep in mind that many have restricted days and hours for service.

  • Bellagio
  • Caesars Palace
  • Circus Circus
  • Cosmopolitan
  • Excalibur
  • Main Street Station
  • MGM Grand
  • Palms
  • Rampart
  • South Point
  • Westgate

Consider a progressive 8/5 Bonus Poker game with a meter that rises by 0.5%. Player A needs to have an immediate advantage to start playing, while Player B is willing to wait for the jackpot to increase, though he too requires an edge in the long run. What is the minimum jackpot amount needed for each player to begin playing? Assume that the machine is a standalone unit, not linked to others.

The return from the fixed pays in 8/5 Bonus Poker is 0.971776. Let’s assume that the player employs a strategy for hitting a royal flush that pays out 800. The odds of achieving a royal flush are therefore 0.0000248551. Let j represent the payout required for a guaranteed 100% return on their investment in the game. So we have:

1 = 0.971776 + j × 0.0000248551
j = (1-0.971776)/0.0000248551 = 1135.56.

Thus, Player A would require a jackpot of at least 1136 full bets of 5 credits each (rounded up) to engage in play. The meter rise is irrelevant for Player A.

Player B approaches the game with a long-term perspective. He will eventually recoup whatever the meter rises by 0.5%. His calculations are similar but account for the value of that rise. The breakeven point j can thus be expressed as:

1 = 0.971776 + 0.005 + j × 0.0000248551
j = (1-0.971776-0.005)/0.0000248551 = 934.39.

When rounded up, Player B would need a jackpot amounting to 935 full bets of 5 credits each.

What is the formula for 13 + 23 + 33 + 43+ .. + n3?

The answer is n2(n2+ 1)/4

Here is a link to my solution (PDF).

The square depicted has a side length of 2. One arc comprises a circle with a radius of 1, while the other has a radius of 2. What is the area of the red section? You may express your solution using trigonometric functions.

4*(arctan(2) + 4*arctan(1/2) – 2) = 3.84695661518926
