The king of the Greek gods has a slot of his own…

If you could pick one god from Mount Olympus to be the theme of our October slot, which one would it be? We picked the slot starring the god with the thunderbolt! Olympus Thunderhold, one of our Greek mythology online slots, is our Game of the Month for October at Thunderbolt Casino. SpinLogic based the game on the Greek myths about Mount Olympus, home of the gods – and the mountain itself is real, with a highest peak of 2,917 metres in Greece!

There's more to our October promotion, though. We've lined up a deposit coupon for the month as well, and you earn double comp points on every bet you place in Olympus Thunderhold. Put the two together and you've got a bigger ZAR balance, while your comp points build up at twice the rate! Of all our Greek mythology online slots, Olympus Thunderhold is the one to launch in October. Talk about lekker timing for a casino named Thunderbolt!

Olympus Thunderhold Slot – A Grid Built for Cascading Wins

Olympus Thunderhold is a six-reel SpinLogic slot among the online slots here at Thunderbolt Online Casino, and winnings are paid for matching symbols anywhere on the grid instead of along paylines. You win with eight or more of the same symbol, wherever they appear, and the bigger the group, the bigger the win. Does that sound simple, Bolters? It is, and twelve or more crowns are the best combination of all the regular symbols!

What's a win worth in rand, then? The values on the paytable are linked to your bet, so the bigger your stake, the bigger every win. At R10 a spin, a dozen crowns come to R500, and that's paid straight into your rand balance! After the crown come the ring, the chalice and the hourglass, while the five coloured gems are worth the least, so keep your eyes on those top four symbols. Here are four more facts about Olympus Thunderhold:

• Total bets range from R0.20 to R160 a spin.
• Its volatility is medium, according to SpinLogic's game data.
• The top award is 2,500 times your total bet - R400,000 at the R160 maximum!
• You play it instantly in your browser, on desktop and mobile, like all our online slots.

Cascading wins follow every winning spin in Olympus Thunderhold. Once a win is paid, the winning symbols disappear from the grid, the symbols above them fall to the bottom, and new symbols fill the empty positions. Any new match is paid as well, and the process continues until no winning combination is left… You can collect several wins from a single spin this way, and of all our online slots, it's the cascade design we enjoy most here at Thunderbolt Casino!

Free Games & the Multiplier Symbol

When four or more Zeus Scatters appear anywhere on the grid, you're awarded 10 free games. During the feature, you're awarded 5 extra free games every time three or more Scatters appear. The Zeus Scatters are paid in their own right as well, and the more of them you have, the bigger the payout. Have you ever seen six Zeus symbols on one grid, okes? Yoh, that's 100 times your bet before a single free game has been played!

The multiplier symbol appears only during the free games, with a value anywhere from 2x to 100x. Each one stays on the screen until the cascade stops, and then the values of every multiplier are added together and applied to the total win from that cascade sequence. How big can that get in rand? Multipliers of 5x, 10x and 25x add up to 40x, so a R50 cascade sequence becomes R2,000… That's R1,950 on top of the R50 cascade win - kief, nê?

For a better chance of the free games, or the round straight away, use one of two optional buttons on the game screen. With Bonus Bet active, more Scatter symbols are placed on each reel and your total bet rises by 25% until you turn it off again. The Buy Feature costs 100 times your total bet, and the triggering spin is played automatically once you've bought it. Only one of the two can be active at a time. Three rules apply to every round of free games:

• Every free game is played at the bet of the spin that triggered the round, and that bet can't be changed.
• The round ends when no free games remain or when the maximum payout is reached.
• Your total winnings from the round are displayed on a banner after the last free game.

How to Claim Your October Match Bonus

Our October coupon is THUNDEROCT300, a 300% match on deposits of R25 or more, up to a bonus of R3,000, and you'll find it in your account inbox with our other live and personalised offers. It's valid until 31 October 2026, and R25 is also the lowest deposit in our cashier - on Lightning Bitcoin. With a R1,000 deposit, the full R3,000 is yours, and you start with R4,000 for our online slots – we think that's nca! This is the coupon at its minimum and at its maximum:

The wagering is 30 times your deposit plus bonus, so the playthrough on a R100 balance is R3,000. You can cash out up to 20 times your deposit once it's complete, and each bet is capped at R100 while it's active. Every slot in our lobby is eligible, so you can play all our online slots, Olympus Thunderhold included, with your bonus balance. Only one bonus can be active on your account at a time, so finish this match before you claim the next!

Remember this one, Bolters – here at Thunderbolt Casino, you redeem a deposit coupon before you make the deposit, and your October match is redeemed the same way. Any deposit figure can be tested on our Bonus Calculator first – it's in the right-hand menu of our lobby. Keep to our online slots until the wagering is done, since playing an excluded game before that point can void the bonus and its winnings. There are four steps in all:

1. Log in to your account and go to its Coupons section.
2. Enter THUNDEROCT300 and redeem it before you make your deposit.
3. Deposit R25 or more in our cashier with Lightning Bitcoin, or any method whose minimum you meet.
4. Open Olympus Thunderhold from our lobby and choose your stake before the first spin.

Earn More Comp Points in Olympus Thunderhold

Comp points are our standing reward here at Thunderbolt Casino, and you start earning them from the very day you first sign up. Once you have 100 or more, they can be exchanged for real rand in the cashier, under My Account. Each month, we choose one game for double comp points, and we announce the star of the show by email. Through October, that star is Olympus Thunderhold, and this is how the two rates compare:

• In our other online slots, you earn 1 comp point for every R10 you wager.
• In Olympus Thunderhold, you earn 2 comp points for every R10 you wager, all October.
• Every 100 comp points are worth R1 in your account.

You rake them comp points on real-money bets, cashback and deposit bonus bets alike, so you collect double points while you clear your October match as well! What does that come to in rand? Clear the full playthrough on a R1,000 deposit in Olympus Thunderhold and you collect 24,000 points, or R240, against 12,000 points in our other online slots. That's rand we're always happy to see land straight back in your account, Bolters!
