Hi All

I have few questions in my mind and would like to get advice from you guys.

Let's say i'm bought a Non-negotiable ("NN") chips $500,
in return the Casino gave me = $500 NN CHIPs + $5 worth of meal voucher + 8 Points (value is the same, 1p = $1).

Question:
1) If the Casino allows me to bet promo chips on all 37 numbers at once.

1st Bet Calculations

• Bet 10NN per number, total 370NN
  Win $350 cash + left with capital 140NN

2nd Bet Calculations

• Bet 5NN for 30 numbers, $5 cash (from the 1st bet winning) for remaining 7 numbers
  Win $175 cash + $315 ($350-$35)

Total hard cash on hand = $490
Total lose = $10

However, i'm getting the rewards given by the Casino "$5 worth of meal voucher + 8 Points (value is the same, 1p = $1)"

Questions
1) Am i right to say that i will actually win $3 worth of reward everytime i use this method?
2) What if the Casino restrict me to bet all 37 numbers at once using NN Chip, will the house edge increase?
3) If they restrict me to bet all 37 numbers. I will bet 19 numbers using NN Chips, 18 numbers using cash chips. Will this make a different?

Looking forward to your reply!
