European Roulette Review

The Game: A wheel with blocks numbered 0 to 36 is spun in one direction. A ball is spun around the wheel and as the ball slows, it drops into one of the pockets of the wheel. You bet on which pocket the ball will drop into.

Odds & Strategy: This is Global Player's 'European' single-zero roulette (with only one zero) which sets the basic house edge* to 2.7%. That's already double as good as the American roulette version which has a basic house edge of 5.26%.
Additionally Global Player Casino makes use of a great and rare to find rule that puts the player in an even more favorable position: the 'la partage' rule (also called the 'en prison rule' or 'Hamburg variation of the European half back rule'): you'll lose only half your money if the zero comes up when betting on the 'outside' bets (the 'outside' bets are the bets that pay even money: high/low; red/black; odd/even). By losing only half your money, the house edge on those 'outside' bets is cut down to 1.35%. Remember, however, that an 'inside' bet still has the single-zero house edge of 2.70% against it.
Consider that inside bets (number bets etc.) offer far better payouts than outside bets, so bet the middle 12 once in a while.
Global Player offers roulette rooms with betting limits of $1-$2000, $5-$4,000 and $10-$6,000.

Where it was criticized before that Global Player didn't offer a good history of spins they recently implemented as an aid for professional roulette players, a tool to extract a record of the numbers of all spins on their $1-$2,000 French roulette table #1. The question remains: why not on all tables?

Summary: That's the best roulette table in the Internet (1.35% house edge only, all day betting history, up to $6,000 betting limit).

American Roulette Review

The Game: American roulette is played the same way as is the European roulette.

Odds & Strategy: This is Global Player's 'American' double-zero roulette (with two zeros) which sets the basic house edge to 5.26%. The 'la partage' rule does not apply, so the casino's edge stays at 5.26%.

It's taken into positive account though that Global Player offers both the European and the American roulette versions. The betting limits here are $1-$2000, $5-$4,000 and $10-$6,000, as well, which simply are the highest betting limits you will find in online casinos. Usually you are not allowed to bet more than about $500 per spin. 

Summary: That's the worst roulette game to play but the betting limits are excellent. Stick to their European roulette version.
