What Caveman Keno Actually Is

Here’s the thing about keno: it’s the one casino game where the house edge is so brazen it’s almost charming. And IGT’s Caveman Keno leans into that with a prehistoric theme, some dinosaur egg extras, and the same fundamental math that’s been separating keno players from their bankrolls since the Han Dynasty.

Caveman Keno takes standard keno and adds a twist. Before each draw, the game randomly selects three dinosaur eggs on the board. If the drawn numbers hit those eggs, your winnings get a bump — typically doubled or quadrupled depending on how many eggs crack open. It’s a clever little dopamine lever. Does it change the underlying odds in any meaningful way? Not really. But it makes the draws more interesting, and in a game that’s pure lottery mechanics, “more interesting” is doing real work.

If you’ve played Cleopatra Keno or Power Keno, you know what you’re getting structurally. Those games add their own twists — Cleopatra gives you free rounds on a 12th ball catch, Power Keno boosts payouts if the first number drawn is a hit. Caveman Keno’s egg mechanic sits in that same family. Different seasoning, same steak. For broader IGT experiences, you might also enjoy their slot work like Magic of the Nile or Cleopatra II, but those are entirely different beasts.

How the Draw Works

Standard keno setup. You pick between 2 and 10 numbers from a board of 80. The game then draws 20 numbers at random. Your payout depends on how many of your picks match — your “catches” — against a pay table that scales based on how many numbers you originally selected.

The Caveman Keno wrinkle: before the 20 numbers are drawn, the game places three dinosaur eggs on random unselected spots. If drawn numbers land on those eggs, you trigger multiplied payouts. Two eggs hit? Your catch payout doubles. All three? Typically quadruples. That’s not nothing — it adds a layer of anticipation that regular keno doesn’t have.

But let’s be honest. The core mechanic hasn’t changed. Twenty numbers from eighty. The probability of catching all 10 on a 10-spot ticket is roughly 1 in 8.9 million. The eggs don’t improve that. They just make certain wins bigger when they do land.

Payouts and the House Edge

IGT hasn’t published a specific RTP for Caveman Keno, which is typical for keno games — the house edge shifts depending on the pay table the operator selects and how many spots the player picks. Broadly, keno sits somewhere in the 5% to 25% house edge range, with most versions landing between 8% and 15%. Compare that to blackjack at under 1% or even roulette at 2.7%, and you see the problem.

Do the math. If the house edge is 10% and you’re betting $1 per round at, say, 30 rounds in 10 minutes, you’re theoretically losing $3 every 10 minutes. Over an hour, that’s $18 expected loss on $180 wagered. That’s the cost of entertainment. Know it going in.

The dinosaur egg multipliers do help redistribute variance — occasionally you’ll hit a boosted payout that wouldn’t exist in standard keno. But they don’t reduce the house edge. The pay tables are adjusted to account for them. If you’re looking to stretch a bankroll further, consider grabbing a no deposit bonus → to test the waters before committing real money.

What a Typical Session Feels Like

Keno is fast and repetitive. That’s either meditative or maddening depending on your temperament. A typical Caveman Keno session involves picking your spots, watching the draw, and either seeing a few catches trickle in or watching the board completely whiff your selections. The egg mechanic adds those moments where two eggs crack and you think “okay, now we’re cooking” — then you catch one number and win basically nothing. Classic.

There’s no skill component here. No decision tree, no optimal play beyond basic number selection strategy (which I’ll get to). This is pure chance-based entertainment. Your session outcome is determined the instant the RNG fires, and nothing you do between games changes the next result.

Bankroll guidance: set a fixed session budget and stick to it. Small, consistent bets. If you’re playing with a $50 session limit, don’t bet $5 per round thinking you’ll hit big early. Bet $0.50 or $1 and give yourself enough draws to actually enjoy the game. And if you’re up 30% at any point? Seriously consider walking. Actually, that applies to every casino game. Anyway — if you want free spins → offers to use on other games, that’s usually a better value play than grinding keno with bonus funds.

Strategy Tips (Such As They Are)

I’m using “strategy” loosely here. You can’t outthink a random number generator. But you can be less reckless about how you approach it.

1. Pick fewer numbers. A 4-spot or 5-spot ticket gives you better catch odds per pick than a 10-spot. The jackpots are smaller, sure, but you’ll actually hit something. The expected return on mid-range picks tends to be better than going for the moonshot.
2. Set a bankroll and treat it as spent. Decide before you start: this is my entertainment budget. When it’s gone, it’s gone. No ATM runs. No “one more round.” This isn’t a profitable exercise — it’s recreation with a price tag.
3. Don’t chase the 10-spot jackpot. Catching 10 out of 10 is a 1-in-8.9-million event. You’re not hitting it. I’m not hitting it. Nobody reading this is hitting it. Play for the modest catches that actually occur.
4. Don’t use bonus funds on keno. Most casinos either block keno from bonus wagering entirely or weight it at 5-10% toward requirements. You’ll burn through a welcome bonus and have nothing to show for it. That’s one of the classic casino bonus mistakes people make.
5. Stop when you’re ahead. If you started with $50 and you’re sitting at $80, that $30 profit is real. Take it. The longer you play, the more the house edge grinds you back to zero. This is just math.

How It Compares to Other Keno Games

They’re all keno at the core. The differences are in the bonus mechanics layered on top. Caveman Keno’s egg system is arguably the most visually engaging of the bunch. If you’re looking to explore IGT’s broader catalog, Rise of Egypt is worth a look — different game type entirely, but solid IGT craftsmanship.

The Bottom Line

Caveman Keno is the most entertaining way to lose money at keno, and I mean that as a compliment. The egg mechanic genuinely adds suspense to a game format that can otherwise feel like watching paint dry with numbers. It won’t change the fundamental economics — keno is a high-edge game and always will be — but if you’re going to play keno anyway, this version at least gives you something to watch between catches. Play it for fun, budget accordingly, and don’t pretend the dinosaur eggs are going to save your bankroll.
