Keno Variants Explained: Cleopatra, Caveman, Superball & Multi-Card

The short answer

Keno variants keep the pick-and-draw core and add one twist each. Caveman Keno adds multiplier "eggs," Cleopatra Keno awards 12 doubled free games, Superball quadruples wins when the first ball hits your card, and multi-card keno runs up to 20 tickets per draw. Documented returns span 82.39% to 95.36%, per Wizard of Odds pay-table analyses (2026).

The keno variant family at a glance

Underneath every name on this page sits the same game: pick your numbers from a field of 80, the machine draws 20, and you're paid by how many it catches. If that base loop is new to you, the full walkthrough of how keno works lives in keno explained. Variants don't touch the draw. They decorate it.

Most of these games live on video keno machines, where the twist is a screen animation: eggs cracking, a golden ball dropping, four cards lighting up at once. For context, Wizard of Odds' 2008 San Diego survey found ordinary video keno returning 84% to 95% of wagers, depending entirely on the pay table loaded into the machine.

Here's the master list, with each variant's documented return range from Wizard of Odds' published analyses (all retrieved 2026):

One pattern to notice before we go variant by variant: no twist is free. Every multiplier and free-game feature is paid for by a leaner base pay table. The feature changes the shape of your wins, not the direction of the math. That's why reading the chart matters more than picking the theme, a skill we cover in keno payout charts explained.

What is Caveman Keno and how do the eggs work?

Caveman Keno is video keno with three multiplier numbers, drawn as dinosaur eggs, layered on top of your ticket. After you pick your spots, the game marks three "egg" numbers among the numbers you didn't pick. Then the usual 20 balls come out.

The eggs decide your multiplier:

• 0 or 1 eggs drawn: your win pays at face value (1x).
• 2 eggs drawn: everything the pay table owes you is multiplied by 4.
• 3 eggs drawn: the multiplier jumps to 8x, or 10x on some machines.

Because the eggs sit on numbers you didn't pick, they never overlap your spots. They're a separate side-draw riding the same 20 balls. You still need a paying catch for the multiplier to matter; four times zero is zero. (If "spot" and "catch" are fuzzy, the keno terms glossary pins both down.)

Now the honest part. Wizard of Odds' Caveman Keno analysis, current as of 2026, documents ten different pay tables in circulation. Their returns run from 82.39% up to 95.36%. That's a 13-point spread on machines that look identical from the chair.

The best documented table tops out at 95.36% on a pick-3 ticket. Another widespread table never does better than 89.63%, and that's at pick-8. Same eggs, same animation, several extra cents kept from every dollar. The eggs are theater; the pay table is the price tag.

How does Cleopatra Keno work?

Cleopatra Keno pays a bonus of 12 free games whenever the last ball drawn contributes to a win. In plain terms: if the 20th ball out is one of your catches, and that catch is part of a hit your pay table actually pays, the free games trigger.

The free games replay your same numbers and stake at no cost, and every win during them is doubled. There's no retriggering; a lucky last ball inside the bonus round won't award 12 more. When the dozen games end, you're back to the base game.

That last-ball condition is stricter than it sounds. It's not enough for the final ball to land anywhere on your card. It has to convert or extend a paying combination. On a small ticket where two catches pay nothing, a last ball giving you your second catch triggers nothing.

The math follows the familiar pattern. Wizard of Odds' Cleopatra Keno page, retrieved 2026, documents common pay tables returning roughly 88% to 95.25%. Its best table sits in the 94% to 95.25% band across picks; its leanest runs near 88%. The free games are pre-funded the usual way: the base pay table gives up a little on every catch to bank the bonus.

Why is the game so popular anyway? Because the bonus arrives as a story. The 20th ball hangs, hits your number, and suddenly you've got 12 doubled games coming. That's a genuinely fun mechanic. It's also, mathematically, just a different way of receiving the same long-run return.

The Superball rule: first ball, four times the pay

Superball Keno quadruples all your wins whenever the first ball drawn hits one of your picks. That's the whole twist: the opening ball is the "superball," and if it lands on your card, every prize on that draw pays 4x.

Your chance of catching the superball is straightforward math. The first ball is one of 80 numbers, so a ticket with four picks catches it 4 times in 80, or 5%. A 10-spot ticket catches it 10 times in 80, or 12.5%.

Wizard of Odds' Super Keno analysis (retrieved 2026) puts quarter-machine returns between 85.98% and 92.99% depending on how many numbers you play, with pick-6 the best documented ticket at 92.99%. As with the other variants, the 4x moments are financed by a base pay table that's leaner than a plain keno chart.

There's a naming trap here worth two paragraphs, because floor signage is sloppier than the math.

Does first ball versus last ball matter to your odds? Not by much; the two games' documented returns land in the same neighborhood. It matters for reading the game correctly, and for looking up the right analysis before you sit down.

Four-card keno: the same bet, multiplied

Four Card Keno, and its bigger sibling 20-card Multi-Card Keno, lets you play up to 20 tickets on the same draw. It doesn't improve the expected return. Per Wizard of Odds' multi-card variance analysis (retrieved 2026), each card keeps exactly the expected value of its pay table. Twenty cards means twenty times the wager per draw, at the same return per dollar.

The worked example on that page uses a common pick-6 pay table (3-4-68-1500). One card returns 90.7591%, a house edge of about 9.24%. Twenty cards on that same table return 90.7591%. The math doesn't care how many cards carry it.

What multi-card play genuinely changes is variance, especially when your cards share numbers. Wizard of Odds computes that overlapping cards leave the expected return untouched but make outcomes correlated; in its example, two cards sharing three numbers carry a covariance of 7.39. Translation: shared numbers hit together and miss together. Your sessions get streakier in both directions, not better.

That correlation is exactly what fans are buying. Writing in Casino Player Magazine, video keno columnist David Stratton says Four Card Keno "revolutionized video keno, much the way Triple Play and Five Play machines revolutionized video poker." The strategy culture is all "cross-over" patterns: overlapping number groups across cards so one lucky draw sweeps several tickets. Stratton describes a draw completing eight solid 7-spots at once, worth about $2,800 on nickel-per-card bets.

Keep the base rate in view, though. A solid 7-spot is a 1 in 40,979 event per card per draw, and a solid 6-spot is 1 in 7,753. Wild Academy computed both exactly in 2026 from the hypergeometric formula, P(k) = C(20,k) x C(60,n-k) / C(80,n). Overlapping cards don't make that draw more likely. They just concentrate more of your money on the same rare event.

So the honest verdict: four-card keno is single-card keno with a bigger bet per draw and a boom-or-bust distribution. If that ride appeals to you, price it per draw, not per card.

The layered hybrids: Caveman Keno Plus, Cleopatra Max, Triple Power

The variant families also stack. Caveman Keno Plus and Caveman Keno Max layer extra multipliers onto the egg mechanic, Cleopatra Max reworks the free-game bonus, and Triple Power Keno extends the last-ball multiplier idea. Wizard of Odds maintains dedicated pages and free calculators for these, including a Caveman Keno calculator that scores any pay table you type in (available as of 2026).

You don't need a separate mental model for each. Every hybrid follows the rule you've now seen four times: the feature is pre-paid by the base pay table, and the loaded chart, not the theme, sets the return. If a hybrid catches your eye on the floor, look up its pay table in the matching calculator before you commit a session to it.

Where can you play keno variants for free?

You can play keno free at Wizard of Odds, which hosts a no-stakes practice game alongside its analyses (live as of 2026). It's the quickest way to feel the pace of the base game before any money moves, and pace is the stat that decides what a session costs.

Searches for "free Cleopatra Keno" mostly want the branded machine experience without the wager. Availability there is generic good news: many licensed online casinos offer demo or free-play modes on their video keno titles, and the variant calculators above let you test any pay table's math for free. Which format to eventually play for real, and what each one costs per hour, is the subject of video keno vs live vs online.

One caution while you browse demos: free-play modes show you the mechanic, not the return. A demo of Caveman Keno feels identical on the 82.39% table and the 95.36% table. The chart still decides.

Which keno variant should you pick?

Pick by documented pay table, then by the ride you enjoy, because the ranges overlap almost completely. Per Wizard of Odds' analyses (2026), the best documented tables sit within about two points of each other: Caveman at 95.36%, Cleopatra at 95.25%, Super Keno at 92.99%. The worst tables in each family give up far more.

That means "which variant" is usually the wrong question. The spread within one variant, 13 points in Caveman's case, dwarfs the spread between variants' best tables. A good Cleopatra machine beats a bad Caveman machine, and vice versa. Verify the chart on the machine in front of you; keno payout charts explained shows how.

Remember what none of these games change: the house keeps a slice of every wager in the long run, and video keno's speed multiplies whatever that slice is. If "return" and "house edge" are still settling in, what is RTP is the ten-minute foundation. Then set a session budget before the eggs start cracking, using bankroll management 101, and let the variant be entertainment rather than a plan.
