Zeus Powerstorm – Bonus Flash 3×3 Slot Review
A white-bearded Zeus leans out from behind the reel frame on a cliff-top perch in the clouds of Mount Olympus, laurel wreath on, glaring down with lightning-bolt eyebrows while rays of light fan out behind him. His glower is the most excitement the reels themselves will give you, because this is a three-reel game that barely uses its reels: the paylines are scenery, and the gold coins and their collector do all the paying.
Spinomenal have built it bright and glossy, all saturated blues and golds, with the whole coin-collecting engine packed into the middle of the screen. It runs on a 3×3 grid with 10 paylines, and while the game client prints no RTP figure, the provider publishes four RTP options (89.28% | 92.34% | 94.23% | 96.06%), the highest being 96.06%. The bonus round carries a x5000 cap. Sister title Bavarian Riches 3 covers similar ground if the Olympian dressing doesn’t grab you.
Base Game & Features
Three reels, three rows, 10 fixed paylines. The grid is compact and the pace is quick, with the god of thunder glowering down from the top of the frame the whole time. Rocky cliffs and green tufts climb the screen edges, and the whole look is built thick-outlined and mobile-friendly rather than cinematic.
The paytable is a short one, because the Bonus symbol, a gold coin, isn’t a line pay in the usual sense. Each coin carries its own cash value, and those values vary from instance to instance:
- Bonus (gold coin) – values per instance, in multiples of stake:
- 1.5x
- 1x
- 0.3x
- 0.2x
- 0.1x
Wins form left to right across the 10 paylines in the standard way, but the coins are the real business of the game. They feed the collector mechanics below rather than paying as ordinary symbols. A coin can land on its own, doing nothing until a collector arrives, or it can land as part of a combination that sends the whole thing straight into the bonus.
Because the values attach to individual coins rather than to a fixed paytable row, two coins on screen at once can be worth very different amounts. What they’re worth together depends entirely on whether a Bonus Collect symbol turns up to claim them. The Jackpot symbols count as Bonus symbols too, so a single coin-family symbol can arrive carrying ordinary value or jackpot weight, and only the collector arrangement tells you which one you’re getting.
Instant Win Feature
When a Bonus Collect symbol lands together with one or more Bonus symbols, including Jackpot symbols, in a combination that doesn’t trigger the Bonus Game, the collector gathers their values and pays them out immediately. The total is added straight to the spin’s win and credited to your balance.
This one runs in the base game only. It’s the consolation prize of the mechanic set. You’ve landed the coins, the collector has turned up to meet them, but the arrangement on the reels isn’t the one the bonus round asks for, so the game pays you out on the spot instead. The coins then clear off the reels with the rest of the spin.
Bonus Blast Feature
At random during the base game, the Bonus Blast can activate. Extra Bonus symbols and Bonus Collect symbols spread across the reels, making sure enough of them are on screen to trigger the Bonus Game.
It’s a nudge mechanic, and when it fires it’s usually the bridge into the main event. There’s no skill or choice in it: the symbols simply appear where they’re needed, and the trigger completes itself. The only thing you do is watch the coins multiply before the reels lock for the transition.

Bonus Game – Hold & Hit
The Bonus Game triggers when a Bonus Collect symbol lands on reel 2 alongside Bonus symbols on reels 1 and 3. The triggering symbols lock in place during the transition, and the round starts with 3 spins. Both Bonus symbols and Bonus Collect symbols can land during it.
Every Bonus symbol that lands is collected by all Bonus Collect symbols on screen: the coin disappears from the reels and its value is added to each collector’s running total. That plural matters. Two collectors on screen at once means every coin pays twice, which is how the totals climb towards the cap.
Empty spots aren’t dead space either. They can randomly award Bonus Game Jackpot multipliers based on your bet:
- x1
- x2
- x3
- x5
- x7
- x10
- x15
The spin counter is generous. Any Bonus symbol or Bonus Collect symbol that lands resets the remaining spins back to 3, so a streaky round can run for a long time. The Bonus Game ends when 3 spins pass without a Bonus symbol landing, or when the total collected winnings reach the maximum x5000 multiplier.
Play it out in order and the shape of a round is easy to follow. Coins land and get absorbed by the collectors. The counter ticks down, then jumps back to 3 on the next hit. An empty spot occasionally throws out a multiplier instead of a coin, which keeps a quiet stretch from being a dead one.
When it ends, the totals from every Bonus Collect symbol are summed and paid out as the Bonus Win. That’s the whole payout structure of the round: coins in, collectors count, one award at the end. There’s no wheel, no pick, no separate jackpot screen – everything resolves on the three reels you started with.
A BUY button sits in the interface for skipping the queue, though no price list accompanies it in the game’s own material. The purchase drops you straight into the round the standard trigger builds towards, with the same 3-spin counter and the same reset rule.
Our Honest Verdict
Overall Rating: 6.9/10
Most of your time here is spent watching three small reels, waiting for the one arrangement that matters: the collector in the middle, coins either side. That wait is the game, and the reason anybody picks it is the round the wait buys. Zeus looks down the whole time like he knows exactly which spin you’re hoping for.
The Bonus Game is the best thing here by a distance. Every hit resetting the counter to 3 means a good round keeps breathing, and with two collectors up, each coin pays twice, so totals can genuinely climb.
What lets it down is the base game, which offers little beyond coins worth fractions of your stake and the occasional consolation payout. Anyone after a three-reeler with proper line wins will find the paytable thin. This one’s for players who like the hold-and-hit build and the long tease before the storm – the cloud-counters and the patient types. If that’s you, Olympus is worth the climb.
