Magnavox’s Odyssey put a translucent roulette wheel on family televisions in 1972. Online roulette screens are still working on the puzzle that plastic overlay set out to solve.
Roulette hands screen designers an awkward brief: half the game is a spinning wooden wheel, the other half a grid of numbers printed on felt. Home consoles, handhelds, PCs and live casino streams have each had to decide which half gets the screen and which half gets pushed to the edges. Meanwhile the wheel itself has barely moved on since the Blanc brothers took the single zero to Bad Homburg in the middle of the nineteenth century. Its stubbornness explains a surprising amount of what Kiwi players see on an online roulette table today.
Why the wheel still runs the show
A single-zero wheel carries 37 pockets, numbered 0 to 36 and scattered around the rim in a deliberate sequence. Clockwise from zero it runs 0, 32, 15, 19, 4, 21, 2, with red and black alternating and zero picked out in green. Paris wheels of the late 1790s marked the single zero red and the double zero black. Green took over in the 1800s to avoid confusion. Phone screens in Tauranga still paint zero green because of it.
Felt works on another logic. Its grid runs 1 to 36 in counting order, in 3 columns of 12. Numbers that neighbour each other on the wheel end up scattered across the table. Online roulette screens handle the mismatch with a racetrack, an oval strip that lays the numbers out in wheel order for neighbour bets and French call bets such as Voisins du Zéro and Orphelins.
| Feature | Single-zero wheel | Double-zero wheel |
| Pockets | 37 | 38 |
| Zero pockets | 0 | 0 and 00 |
| Sequence from zero | 0, 32, 15, 19, 4, 21, 2 | 0, 28, 9, 26, 30, 11, 7 |
| Where it spread | Monte Carlo and most of the globe | United States |
Kiwi players can find the single-zero classic at Volt Rush NZ, whose live lobby lists Roulette next to Blackjack and Baccarat tables. Evolution and Playtech power that lobby, connecting players to professional dealers and real tables through HD, low-latency streaming. Its homepage adds that each result happens live on screen. Its homepage also files Lightning Roulette under game shows next to Crazy Time, a hint at where wheel design went next.
A plastic wheel stuck to the family TV
Magnavox launched the Odyssey in the United States in September 1972 at US$99.95. In History.com’s Brown Box history, Dave Roos traces the console back to Ralph Baer’s prototypes at Sanders Associates and quotes video game historian Alexander Smith, who says “Television in the 1960s was a very static medium.”
According to Roos, the Odyssey came with a dozen games, along with screen overlays and board game-style accessories. With no microprocessor on board, the Odyssey could draw white spots and a vertical line on screen. Anything fancier had to be printed. Players bet with chips and spun a controller dial to launch a spot of light at a roulette wheel overlay, a translucent sheet that clung to the glass by static. Its box also packed dice, poker chips, play money and card decks. Much of the Odyssey’s fun took place off-screen.
Wheel on the screen, bets on the coffee table: home roulette’s opening layout split the game down the middle. Online tables eventually pulled the coffee table onto the display.
Pixels learn to spin
Mattel’s Intellivision console went a step further with Las Vegas Roulette, released in the United States on 3 October 1980 and developed by APh Technological Consulting. Its screen skipped a full wheel. A numbered strip of American wheel pockets ran across the top, cycling sideways while the ball travelled the opposite way beneath it until both slowed and the ball settled in a slot. In a single strip of sprites, Mattel kept the piece of physics that gives roulette its feel: wheel and ball moving against each other.
Bets went down through the controller disc, with a chip placed on the line between 2 numbers for a split. Programmer John Brooks hid his name on an alternate title screen, unlocked with a button combination and a press of Reset.
HAL Laboratory, the Kirby studio, built roulette into Vegas Dream on the NES. It launched in Japan as Viva! Las Vegas on 30 September 1988 and reached North America in April 1990, with a local news station reporting on your encounters around the fictional HAL Palace Hotel. Its sequel Vegas Stakes arrived on the SNES on 10 April 1993 with 5 casinos and a computer companion (Cliff, Maria, Isabelle or Richard) tagging along in single-player.
Roulette in those games became a scene inside a full casino. It was an early sign that the setting around the wheel can be part of the game.
Live cameras put the real wheel back on screen
Live roulette closes the loop the Odyssey opened. A real wheel is back on screen, filmed this time, with the betting grid drawn over the video as an interface. Whatever the format, the camera has 4 beats to catch:
- Dealers send wheel and ball spinning in opposite directions.
- A slowing ball passes the deflectors on the rim.
- A pocket catches the ball.
- A winning number lights up on the on-screen grid.
On an American Roulette table today, the 00 pocket that scrolled across the Intellivision strip in 1980 turns on a real wheel. Evolution’s own catalogue shows how far studios now push the format. Lightning Roulette arrived in 2018 and XXXtreme Lightning Roulette in 2022, according to Evolution’s company timeline. Red Door Roulette followed in 2023, described by CDC Gaming Reports in May 2025 as a blend of Lightning Roulette and Crazy Time with a slot round, a key hunt and a giant virtual wheel. Monopoly Roulette is the newest arrival. In June 2026, Evolution’s Monopoly Roulette announcement described a slot machine assigning up to 7 Monopoly bonus symbols to Straight Up numbers each round, with up to 5 other numbers marked as Community Chest spots. A winning Monopoly number triggers 5 to 9 dice rolls, with Mr. Monopoly moving around the board collecting cash prizes and multipliers of up to 5,000x. A Community Chest win has players pick from 3 shuffled cards, each hiding a multiplier of up to 300x. Side bets called Bonus Chaser and Chest Chaser automatically cover each number carrying the matching bonus symbol in a round. Todd Haushalter, Evolution’s chief product officer, said the studio “wanted to create a roulette experience where every spin feels dynamic, engaging, and packed with anticipation.”
Even the newest layer hangs off individual pockets on a wheel the Blanc brothers would recognise. Each bonus still has to be read against a number on the grid, so the extra graphics only work when the pocket underneath stays easy to spot.
4 things the physical wheel still decides on an online roulette screen:
- Pocket order, copied by the racetrack for neighbour bets
- Green zero pockets, a colour choice from the 1800s
- Opposing motion between wheel and ball
- A split between the spinning object and the betting grid
Through 5 decades of screens, the wheel itself has stayed put. Designers keep building around it.
Online roulette puts real money on the line. Only adults aged 18 and over should play, with stakes kept to an amount you can afford to lose. Pick that amount before the wheel starts turning.
