Overview
Climb the marble steps to Mount Olympus in Games Global/Gold Coin Studios’ Olympus Storm slot. With 5 reels and 25 paylines, face off against powerful Greek gods at UK slot sites, from 25p per spin.
Each time a non-winning prize symbol lands in the base game, the Storm Levels progress bar increases. Each Storm Level awards the following:
- Level 1 (Slight): Lightning randomly strikes, adding wilds or prize symbols to the reels
- Level 2 (Moderate): Wheel symbols can land as overlay symbols on reels 1-5. Each time a wheel lands, the Mega Jackpot increases and the Jackpot Wheel Bonus can trigger.
- Level 3 (Severe): The Free Spins Wheel symbol is added to reel 5 during free spins: it awards 1 spin of the wheel when collected via Connectify Pays.
- Level 4 (Olympus): The Collect symbol added to reel 1 during the base game, which allows the feature to trigger from ends of the gtid. When Collect lands on reel 1 and 5, all prize symbols are paid out twice.
When it comes to Jackpot prizes, the Mega Jackpot will increase in the base game once Storm Level 2 is active. Each Wheel symbol landing in the base game will increase the Mega Jackpot by 1 x bet. If won during the free spins, it will award the maximum value of 5,000 x bet. The Major, Minor, Maxi and Mini Jackpots are worth 200, 50, 10 and 5 x bet, respectively.
The Express Collect feature is triggered when prize symbols land on reels 1-4 and a Collect symbol lands on reel 1 or 5. They land on reel 1 only after Storm Level 4 is active. Prize symbols are worth up to 200 x bet. As mentioned above, a Collect symbol landing on reels 1 and 5 will see the Prize symbols awarded twice. In the Jackpot Wheel Bonus feature, the wheel spins and awards 1 of the fixed jackpots. If the Mega Jackpot is won, it is reset to its minimum value.
Then you have the Connectify Pays Free Spins feature: it can be triggered by 1 or more Power Combo symbols in the base game. The active free spins features correspond to each Power Combo symbol:
- Zeus Power Combo: has a chance to trigger the X-Large feature with 8 free spins, played on a 6 reel grid, with 3 locked rows. When an X-Large symbol appears on reel 1 and connects the Connectify Pays system, 1 of the locked rows opens on the next free spin. This allows for more lightning strikes.
- Artemis Power Combo: has a chance to trigger the X-Array feature with 8 free spins. The reels stretch horizontally to add 4 new columns beyond reel 5. Lightning can strike these reels, creating extra connection routes that make it possible to collect a reel-five symbol twice in a single spin when 2 separate paths appear.
- Hades Power Combo: has a chance to trigger the X-Spins feature, with 8 free spins. If the X-Spins symbol lands on reel 5, it adds extra free spins.
You can also combine 2 or more Power Combos, with their effects stacking together. During the free spins, 2 or more wheels can appear on reel 5. Activated at Storm Level 3, the Free Spins Wheel awards free spins, cash prizes or 1 of the jackpots. If a Random Jackpot symbol appears on reel 5, you’ll trigger a Jackpot Jumbo Spin: this can award 1 of 5 jackpots, with the Mega Jackpot worth 5,000 x bet.
With a 96.33% RTP rate, the beautifully-design Olympus Storm comes with 5,000 x bet max wins: head to Mount Olympus with the free demo (below). At OLBG, there are 500+ free demo slots to play for fun.
