In some examples, the roulette wheel may include one or more cameras to capture aspects of the physical spin (e.g., the movement of the wheel and ball) in real time. Graphical elements may be customized during the spin based on the captured images. For example, if a player bet on a number associated with a player's jersey in a football themed game, landing on that number could cause the display device to display an animation of the player running for a touchdown. In some examples, the display device may be transparent or semi-transparent when not in use. The display devices may also be customized based on expected viewing angles for players of the roulette game.
In some examples, the display may synchronize displayed numbers, symbols, graphics (e.g., emoji), and/or positions to the physical pockets of the wheel, and may be changed and/or randomized over time to add additional randomness to the roulette spin.
In some examples, the betting field may include a display device. For example, the betting field display device may display a sports field graphic with betting opportunities and/or bonus game triggers corresponding to players, jersey numbers, field position, player actions, etc. For example, in a football themed game, a bonus spinner displayed by the wheel could determine a first-down position for the next play on a real or simulated game being displayed on the table, with a multiplier or other bonus being awarded if the actual game result matches the bonus spinner value. In another example, players could wager on game events, such as when a next down will run and/or number of yards on the next play.
In some examples, the roulette wheel could select lottery numbers, as part of the main game and/or bonus game. For example, a player may purchase a lottery ticket at the table, with the numbers being valid for one or more spins, for a predetermined amount of time, and/or for an amount of time the player is playing at the roulette table.
In some examples, the roulette wheel display may display a monetary and/or non-monetary award. The roulette wheel display may also be dynamically themed, e.g., for a particular holiday or sporting event, or may accept user input. For example, a player could link his phone to the table and upload a family photo, which could be displayed on the table display device in the event of a win by that player. In this manner, these and other embodiments provide a unique technical solution to the technical problem of providing additional features at a roulette game, such as a physical roulette table game.
