Yeah... never liked roulette! Definitely need a careful strategy to play it.
All those giant casinos are built from the $ taken from folks who thought they had a "careful strategy" for gambling.
Roulette (barring folks wanting to run a team with computers and lasers and risk felony charges in many though not all jurisdictions) is the dumbest game in the casino.
They literally write out on the table the actual numbers showing you it's a losing bet every single time.
Any single number pays 35:1... but there's 38 single numbers (37 overseas)
Any Column pays 2:1.... but there's 3 colums.
Any 12-number-group pays 2:1... but there's 3 groups.
Red/Black pay even money. But there's two numbers that aren't red OR black (one that isn't overseas)
If you wanna lose money slowest at a casino table game and can count cards ok (or maybe even win a bit if you're very good at it) you play blackjack.
(or if you can still find a full pay video poker machine, do that and just play correct strategy)
If you wanna lose money slowest at a casino table game without doing any work (but be a little unpopular) bet the don't pass line at craps.
Both of those can be profitable if you do it at a casino with high-end enough free liquor
Personally I stick to poker, the only place you don't have to worry about a built-in house edge and just have to beat the other players... since unlike this thread casinos don't offer you the chance to BE the house.
