Regarding bingo, I ran some simulations on it trying to see how good it is on average (and what strategy is best). Here's some statistics:
Chance of bingo: ~18%
Chance of 1st bingo: ~10% at 10-person table, ~7% at 20-person table
Chance of super bingo: about 1 in 2500
Expected gain (per game): ~7k at 10-person table, ~40k at 20-person table
* Note that a significant amount of this comes from that slim chance at a super bingo, so it is highly variable. Without taking it into account, the expected gain is only around 10k at the 20-person table, a mere 10% of the starting bet.
* Another note: The chance of 1st bingo and expected gains would be higher if the room isn't full. I'm not sure if that's possible, does the game force the room to be full before starting?
