The question sounds simple. Two types of games, one casino, which one takes less of your money over time. The answer is in the math, and the math is not close.
What "costs less" actually means
House edge is the percentage of every dollar wagered that the casino keeps, on average, over a large number of rounds. It is not what you lose in a single session. It is what the math guarantees the casino will collect if you play long enough. A lower house edge means a slower drain. That is the only metric that matters when comparing formats.
RTP (return-to-player) is the flip side. An RTP of 96% means the game returns $96 of every $100 wagered, on average (Slot Machine Returns aka RTP). The house keeps $4. These are long-run averages across millions of rounds, not a promise for your next 100 spins.
The slots picture
Online slots typically carry RTP rates between 94% and 96%, which puts the house edge at 4% to 6% depending on the game (Slot RTP Explained: How to Find the Best Payout Slots). That range is already wide. A 94% RTP game costs you 50% more per dollar wagered than a 96% RTP game. Most players never check which one they are loading.
The range actually runs wider than that. Slots can carry a house edge anywhere from 2% to 15% depending on the game and platform. Land-based slots in Nevada averaged a 7.2% house win percentage in 2024 on $10.5 billion wagered (Casino Slots Data: Nevada Reports RTP Decrease in 2024). Nevada penny slots posted a 9.36% hold rate that year. Online is better than land-based, but the variance in quality across the catalog is real.
On top of the base RTP, slots carry structural costs that are easy to overlook. Progressive jackpots reduce the base RTP of the game to fund the prize pool. Bonus buy features price in a premium for skipping to the feature. Max win caps limit upside in ways the game title never mentions. The stated RTP is often the best-case number before those mechanics take their cut.
Volatility adds another layer. A high-volatility slot might have a respectable 96% RTP on paper, but what volatility actually does to your session is distribute that 4% loss in concentrated bursts rather than a steady bleed. The expected cost is the same. The experience is not.
The Originals picture
The 13 Originals on Chips.gg are built in-house, and the house edge on all of them is 1%. That puts the RTP at 99%. For a direct comparison: at 96% RTP on a slot, the house keeps $4 per $100 wagered. At 99% RTP on an Original, the house keeps $1. The Originals cost one quarter as much to play, in expected-value terms.
The mechanics behind this are also structurally different. Originals use a provably fair system: a cryptographic combination of server seed, client seed, and nonce generates each result. After any round, you can independently verify that the outcome was not manipulated. Standard third-party slot RNG systems do not offer that. You are trusting the provider's certification. Provably fair is worth knowing about, though it is a separate measure from RTP. Verifying a round proves the process was fair. It does not change the house edge. Both things can be true at once.
The math, side by side
Assume 500 rounds at $1 per round. Same bet size, different format.
- Slot at 96% RTP: expected loss = $500 x 0.04 = $20
- Original at 99% RTP: expected loss = $500 x 0.01 = $5
Volatility will scatter actual results around those numbers. You might finish a slot session ahead. You might lose more than $20. But the gravitational pull is $20 on the slot and $5 on the Original. Over thousands of rounds, the math converges on those figures.

Where slots still make sense
The Originals win on pure cost-per-dollar-wagered. Slots offer something else: catalog depth, narrative design, licensed IP, mechanic variety. If a particular slot experience is what you want, knowing its RTP lets you pick the better-built ones. Check the RTP before loading. Anything below 95% is a meaningful penalty. Understanding the reel math helps you read what the payline structure is actually offering before you commit a session bankroll to it.
The catch with Originals is the opposite: simpler mechanics, smaller catalog. Crash, Dice, Mines, and the others are clean and fast. If that suits your session style, the cost advantage is real and consistent.
The honest verdict
It is still a casino. The house keeps its edge on every format. Players in aggregate lose. That is how the math works, and no RTP number changes it.
What the RTP does is tell you how slowly or quickly the edge operates. On the Originals, it operates at 1%. On a typical slot, it operates at 4% to 6%, sometimes higher. Over any meaningful volume of play, that difference compounds.
If minimizing expected cost is the goal, the Originals are the straightforward answer. If the slot experience is what you are here for, at least pick the games where the math is working less hard against you.
