The first decision is whether the game is physical or digital
Casino table games are developed along two very different paths. A physical game—something played on a felt layout with cards, dice, or a wheel—is a manufactured product. A digital table game is software. The two share a design language, but the people who build them, the tools they use, and the way the finished game reaches a casino floor have almost nothing in common.
A physical game starts as a prototype on a designer's table. The designer works out the rules, the layout, the betting spots, and the payouts, then plays through thousands of hands with real cards and chips to see where the game breaks. A digital game starts as a specification document and a math model, and the first playable version is usually a simulation rather than a physical object.
What both paths share is the same core question: does the game give the house a built-in mathematical advantage while still feeling fair and playable to the person sitting across the table?
Every table game begins with a math model
Before a single card is printed or a line of code is written, the developer defines the game's return structure. This is the part of the process that determines how much of each wager the game returns to players over a very large number of hands, and how much the operator keeps.
Return to Player (RTP) is a theoretical percentage of total wagered money a game returns to players over a very large number of spins or hands. It is a long-run statistical average, not a per-session guarantee. The house edge is the mathematical advantage the operator holds on a given game, expressed as a percentage of each wager. House edge and RTP are complements: they sum to 100% for the same game.
The designer starts by choosing where the edge comes from. In blackjack, the edge is built into the order of play: the player acts first and can bust before the dealer even draws. In roulette, the zero pocket does the work. In a new proprietary game, the designer has to engineer an edge into the rules themselves—perhaps by changing how often a particular hand pays, or by adding a side bet with a different return structure.
The math model is not a single number. It is a document that maps every possible outcome, every bet size, and every rule variation to a probability and a payout. A designer will typically run millions of simulated hands to confirm that the observed return converges on the theoretical figure.
Volatility shapes how the game feels
Two games can have the same RTP and play completely differently. The difference is volatility, sometimes called variance. Volatility describes how payouts are distributed over time. High volatility means rarer but larger payouts; low volatility means more frequent but smaller ones. Volatility does not change a game's RTP.
A designer chooses volatility deliberately. A low-volatility game produces a steady stream of small wins, which keeps players at the table longer. A high-volatility game produces long dry spells punctuated by large payouts, which creates a different kind of tension. Neither choice changes the long-run return; it only changes the shape of the ride.
For a physical game, volatility is usually baked into the payout table. A side bet that pays 100-to-1 on a rare hand is a high-volatility addition, even if the main bet is steady. For a digital game, volatility can be tuned more precisely, because the software can adjust the frequency of near-miss outcomes and the distribution of bonus rounds without changing the overall return.
The rule set is the product
For a traditional game like blackjack, the rule set is not invented by the developer—it is inherited, and then modified. Published basic-strategy charts derive from the specific rule set in use: deck count, dealer stand rules, doubling and splitting rules. A developer who wants to offer a blackjack variant changes one or more of those rules and then recalculates the entire math model.
Changing a rule is not cosmetic. If the dealer stands on soft 17 instead of hitting, the house edge moves. If the player can double after splitting, the edge moves the other way. Every rule change forces a new simulation run, because the edge is a property of the whole rule set, not of any single rule in isolation.
For a new proprietary game, the developer has to write the rule set from scratch, and then defend it. The game has to be learnable in a few minutes, playable at a reasonable speed, and mathematically sound. A game that is too complicated to explain at the table will not survive, no matter how elegant the math.
Physical games go through a different approval path
A physical table game has to be manufactured, and the manufacturing process is part of the development process. The layout is printed on felt, the cards are sourced, the chips are ordered, and the whole package is assembled into a product that a casino can buy and install.
Before a physical game reaches a casino floor, it is usually evaluated by an independent testing laboratory. These labs examine the game's math, verify that the payouts match the published rules, and confirm that the equipment functions as intended. The certification covers game mechanics, not an operator's financial conduct.
A digital table game goes through a parallel process. The game's random number generator—the algorithm that determines game outcomes—is tested for statistical randomness. Independent testing laboratories are commonly used to certify RNG behaviour. The certification confirms that the outcomes are not predictable and not biased, but it does not say anything about how the operator runs its business.
Digital table games are built on the same math as physical ones
A digital blackjack game and a physical blackjack table are different products, but they share the same underlying math. The digital version uses an RNG to shuffle and deal, while the physical version uses a shoe of cards and a dealer. The return structure is the same, assuming the rule set is the same.
The development process for the digital version is a software project. A team writes the game engine, the user interface, the animation, and the sound. The math model is implemented in code, and the game is tested against the model to confirm that the observed outcomes match the theoretical ones. The testing is usually done by a combination of automated simulation and manual play.
Some digital table games are live-dealer games, which are a hybrid. A physical dealer deals real cards or spins a real wheel in a studio, and the player bets through a software interface. The development process for a live-dealer game includes both the physical equipment and the streaming software, and the two have to work together without introducing a discrepancy between what the player sees and what the system records.
What changes and what stays fixed
The development process differs depending on whether the game is physical, digital, or live-dealer, but the underlying math is the same discipline in all three cases. The table below compares the three paths.
| Aspect | Physical table game | Digital table game | Live-dealer game |
|---|---|---|---|
| Core deliverable | Felt layout, cards, chips, rule card | Software application | Studio equipment plus streaming software |
| Outcome generator | Physical cards, dice, or wheel | RNG algorithm | Physical dealer plus camera |
| Math model | Documented and lab-tested | Implemented in code and simulated | Documented for the physical component, with software verification |
| Approval path | Independent testing laboratory | RNG certification plus game testing | Both physical and software testing |
| Rule changes | Printed on the layout | Configured in the software | Set by the table rules in the studio |
Why some games never reach the floor
Most table game concepts never become products. A game can fail for a dozen reasons: the edge is too high and players reject it, the edge is too low and operators reject it, the rules are too complicated to explain, the pace is too slow to generate enough decisions per hour, or the game simply does not feel fun.
The fun problem is the hardest to solve, because it cannot be simulated. A designer can run a million hands and prove that the math is sound, but the only way to know whether a game is enjoyable is to watch real people play it. Physical games are often tested in a single casino for a limited run before a wider rollout. Digital games can be released to a small audience and monitored for engagement.
A game that survives all of that still has to be maintained. Rules get clarified, payouts get adjusted, and digital games get patched. The development process does not end when the game launches; it ends when the game is retired.
FAQ
Who designs new casino table games?
New table games are usually designed by independent game inventors, small studios, or the game development arms of larger equipment manufacturers. The designer is responsible for the rules, the layout, and the math model. A separate testing laboratory then verifies the math before the game is offered for sale or licensing.
How long does it take to develop a new table game?
There is no single answer, because the timeline depends on the path. A physical game can take months to years from first prototype to casino floor, including lab testing and a trial run. A digital game can move faster, but the certification and simulation work still takes time. The limiting factor is usually the testing and approval process, not the initial design.
Do digital table games use the same odds as physical ones?
They can, but they do not have to. A digital blackjack game with the same rule set as a physical table has the same theoretical return. However, a digital game can offer rule variations, side bets, or different deck counts that change the edge. The odds are always a property of the specific rule set in use, not of the platform.
