Helios Fury

Helios Fury by Relaxgaming is a high-volatility video slot with a connected-ways mechanic, played on a 5-reel base grid (3 rows) that expands under certain conditions. The theme draws heavily on Greek mythology, centering on the sun- god Helios, with the action set in ancient Rhodes under siege, bringing drama, ships, shields, helmets and fiery visuals to the reels. Wins in the base game occur via 99 connected ways, where matching symbols in adjacent columns (including rows above or below) from leftmost reel count. A wild symbol both substitutes for other symbols and triggers a Wild Re-Spin whenever it contributes to a win; it shifts one reel to the right with each respin, continuing as long as it remains part of a winning combination.

Landing a wild on reel 5 in a winning combination unlocks the Fury Free Spins feature: you get 6 free spins, the grid expands by 2 rows (making it 5 rows high) and win ways increase to 259. During Free Spins, wilds that land stay sticky and give you an extra spin each; wilds involved in wins walk to the right toward a “hot spot” on their row and when they reach it, they stay there and give another free spin. The hot spot moves one reel to the left if already occupied, until that row is filled with wilds.

There is also a Bonus Buy option (where allowed) that lets players purchase the Fury Free Spins feature directly for 90× the stake. Helios Fury stands out for its potential max win of up to 50,000× the bet, driven largely by the walking/sticky wilds, expanding grid, and retriggerable free spins mechanics.

You can play it for real money.
