Gold Bar Roulette is Evolution's roulette variant with a persistent gold-bar balance. A successful straight-up wager can award cash and bars, and the bars can then be placed on chosen number spots in later rounds. Players can use individual bars or stack several on a chip according to the displayed rules. Unlike Gold Vault Roulette, the central feature is choosing where previously earned bars are used, rather than receiving only randomly assigned multipliers for the current round. The underlying task remains predicting the wheel's winning number; selecting a bar position does not control the ball.
