Ancient Thunder Keno is one of the best real money keno games in the US. Powered by GVG, you know it is fair and legit, which is why it is available to play in licensed US online casinos.

In fact, this game is among the few online keno titles you will find in the US. It is available in any of the listed casino sites, but we recommend playing it from the DraftKings Keno lobby. That’s because this online casino features the random $1,000 DraftKings Jackpots across several games, including on Ancient Thunder.

Aside from this, any of the following operators awards new players a welcome bonus, a sign-up bonus, and regular reload bonuses that apply on keno games.

What is Ancient Thunder Keno?

Keno is a luck-based game that has been around for decades, but it is now available at many online casinos. It’s a fun numbers game comparable to the lottery, and playing it online is as easy as picking your lucky numbers, making a bet, and hoping to strike those numbers when drawing. Ancient Thunder Keno delivers the same experience with a standard grid and numbers ranging from 1 to 80.

The Greek theme has been retained throughout the gameplay, with each numeric square carved out of stones. You must choose certain lucky numbers you believe will be drawn and then press the draw button to see whether you match and win. The more numbers you match during the relevant drawing, the higher rewards you will receive.

The main attraction of this Keno experience is the randomly picked 15 bonus spots. These provide Greek Gods bonus features which you can activate by filling their character cards with hits.

  • Ancient Thunder presents a grid with 80 numbers; you have to mark them as you see suitable. You must select at least three to ten numbers to bet on which you believe will be hit.
  • Mark the numbers and then use the Bet & Denom buttons below the grid to make your total bet, ranging from $0.01 to $20. You can also click the Max Bet option to select the maximum bet allowed, while the Pick button will randomly mark 10 numbers on the grid for you.
  • After that, the Draw button activates, and 20 numbers are drawn randomly as soon as the game starts. A green hit mark will appear when a drawn number matches the selected number. If you achieve the required number of hits, you will be paid according to your bet size and the pay table displayed in the upper right corner.
  • There is also an Auto Draw button to pick between 10 and 200 uninterrupted autoplay. You can also use the Clear button to remove all marked numbers, and the Speed button lets you manage the game’s pace.

Ancient Thunder Keno Paytable and Casino Game Payouts

Ancient Thunder Keno Paytable

The paytable for Ancient Thunder Keno varies according to the number of spots you choose and your bet levels. On the game screen, a paytable displays your expected payout based on the number of hits and the numbers you selected. The odds of winning are extremely low if you select less than four, but if you select more than eight, you will always need to match at least four numbers to get a prize.

Picking more numbers and placing higher bets will result in better payouts, so try to hit enough of your picks to win a prize. If you match all ten numbers drawn while paying the maximum bet, you can win as much as $50,000.

The wheel has twelve prizes; if you play with the maximum bet, you can win 20,000 times your stake in this bonus.

Free Games

There is also a great God, Poseidon, who throws free games into the action, similar to free spins in slot machines. You must hit all four Poseidon God symbols to activate this bonus. How many free games you can get depends on how many spots you selected in the base game.

Ancient Thunder Keno House Edge & RTP

The RTP of the Ancient Thunder Keno slot machine is 93.89%, which is the amount paid out to the player over an extended period. Even though the game has a low RTP compared to online slots, it is still popular because it’s much more fun to play and less boring than traditional Keno. Compared to the standard 85% RTP in online Keno games, the Ancient Thunder Keno RTP is way superior.

The house edge in this keno game is 6.11% on average, according to the RTP of 93.89%. The house edge is the mathematical advantage casinos rely on to profit from player bets over time. The house has a 4% to 15% advantage over players’ bets in online keno games, which appears similar to many slot games.

Ancient Thunder Keno Strategy & Tips to Play

There is no proven strategy to win in Ancient Thunder Keno, but this might keep players looking for whatever benefit they can uncover. We’ve included some popular keno tips, but none of these comes with a 100% guarantee to win.

Picking hot or cold numbers and sticking to betting on them is the most common keno strategy. But remember that it’s a game of chance, so focusing your approach on the expectation that a number will shortly hit could not provide the desired outcome.

Also, increasing the number of spots you bet on might increase your winning odds. However, this technique will cost extra, so be sure your budget can afford it. Play responsibly and set up a budget and your spending limit.

Even when you have mastered the finest keno strategies, we advise practicing in free mode first to improve your understanding of the game further.

Is Ancient Thunder Keno Rigged?

As previously stated, Ancient Thunder Keno is a luck-based game, which means you cannot control or guess the results. All numbers in online Keno are drawn using an RNG (Random Number Generator), which ensures that keno outcomes are genuine and random. The RNG software employs a complex numerical formula to achieve random outcomes distinct from prior draws.

You can play this game at any of our reputable casino sites, which are continually reviewed and inspected by expert organizations to make sure their RNGs are operating legitimately. So, the game is not rigged and operates regardless of the player’s decision about their number selection; at least when you play it on legit and trustworthy online casinos we recommend. The same is true for other US-licensed keno games like Mad Yeti and Prairie Thunder Keno.
