Zeus doesn’t just hurl lightning bolts — he also fronts this 3x3 slot with a face like thunder and a prize structure to match. Storm of Olympus by 3 Oaks Gaming delivers a Greek mythology theme that’s more than just the usual laurel wreaths and ionic columns. The setup is minimalist on the surface, but this title does something different: it skips base game wins entirely and moves straight into a bonus-based structure. That’s right — if you're spinning without bonuses, you're technically spinning for nothing.
The grid is made up of three reels and three rows, with a single function: land three bonus symbols on the middle row to activate one of two bonus modes. There are no paylines in the traditional sense — wins and values are entirely tied to the features that follow. Spins can be placed from 0.10, and everything else is centred around triggering the bonus game.
3 Oaks Gaming has a history of tinkering with mechanics in otherwise familiar themes. While Storm of Olympus is not connected to any earlier titles, it joins a roster of games like Sun of Egypt and Hit More Gold! that lean heavily on feature-driven structures and fixed jackpots. This one's clearly cut from the same cloth — just with a few more lightning bolts stitched in.
Here’s how you can get started and play Storm of Olympus for yourself:
If you aren't already registered, click on the green 'Sign Up' button in the top right corner and fill in the required fields. You can then verify your account and make a deposit if you want to play Storm of Olympus with real funds.
You won’t find your typical lineup of card suits or themed icons here. Instead, the only symbols worth noting are the bonus ones — these are where the action happens. The payouts listed below only apply during the bonus games, not the base game.
Symbol Type | Payout Value |
Regular Bonus Symbol | 1x – 4x bet |
Sticky Bonus Symbol | 5x – 9x bet |
Mini Jackpot | 10x bet |
Minor Jackpot | 20x bet |
Major Jackpot | 50x bet |
Grand Jackpot | 500x bet |
The bonus symbols aren’t just static — some are Mystery symbols that transform into one of the above, while others might represent jackpots directly. There’s also a Collector symbol that doesn’t show a value itself but plays a key role in gathering others.
Triggering the Bonus Game requires three bonus symbols to land across the middle row. When it happens, the base grid is replaced with a clean 3x3 setup. All bonus symbols that triggered the round are held in place, and players begin with three spins. Any time a new symbol lands, the counter resets. When spins run out or the grid is full, the round ends.
During this round, players can land regular bonus symbols, jackpot symbols, Mystery symbols (which convert to a bonus or jackpot), or a Collector that sums the values of all symbols in view. The goal? Fill up the board or rack up values that edge toward the 500x cap.
This is a rarer version of the bonus round and can trigger randomly in place of the standard one. It plays out similarly, but with a twist: the grid is seeded with position-based multipliers from the start. These can range from x1 to x9 and are applied to the symbol that lands in that spot. Additional multipliers can appear mid-feature too.
The difference in potential is notable — the Ultra version increases the odds of potentially hitting higher values or jackpots, especially when Collector symbols combine with multiplier spots.
This blue symbol scoops up the value of all bonus and jackpot symbols on the grid. It only activates once and doesn’t stick around for multiple collections. If it lands in a boosted position, the collected value gets even better.
Mystery symbols reveal any bonus symbol aside from sticky ones, while Jackpot Mystery symbols reveal either the Mini, Minor, or Major jackpot. These can drop a little drama into the grid, especially when they potentially land on positions with a multiplier.
Storm of Olympus ditches the base game wins and leans hard into bonus mechanics, jackpot symbols, and grid-filling potential. If that kind of structure grabs your interest, you might also want to look at games like Sun of Egypt 3 or Hit More Gold! Hold and Win — also from 3 Oaks and also available at BetVictor.
