I played $100 on a single Roulette bet. I think I played $5 on 0, $5 on 00, $5 on 1-12, $2 each number from 1-18($36), $1 each number 19-36($18), $10 on black,$5 on red, $15($5 each 2:1 column) on all three 2:1 columns, $1 on 19-36. When I got 00 I made roughly a $80 profit. What about you guys? What is the single most expensive bet you have ever made in a Casino?
