Legend of Helios Online Slot Review

Legend of Helios is a 5 reel, 25 fixed paylines video slot featuring mystery stacks, re-spin with locking mystery stacks, a bonus wheel with instant prizes, and four free spin features. The base game features a 4-3-4-3-4 reel array with 25 fixed paylines. However, the gameboard can morph into a 4×5 reel array for more win opportunities in the Free Games.
The Sun is the Wild symbol, and it substitutes all other symbols in a winning combination except the two bonus scatters; the green and the bronze. So landing three scatters on reels 2, 3, and 4 triggers the Bonus Wheel. The bronze icon on reel 4 indicates how many bonus wheel spins you have. It can be 1, 2, or 3.

Bonus Wheel

If you are lucky and win more than one spin on the Bonus Wheel, The game will accumulate the prizes for each Bonus Wheel spin, and then you will play each Free Games round sequentially.

When you win free games with a 4×5 reel array and 50 payline grid, each Scatter symbol that appears during Free Games will add an extra spin to the Free Games counter. For example, on the wheel, the following combinations can happen:

14 Free Games with 3x Win Multiplier.

12 Free Games with 3x Win Multiplier and Bursting Wilds

10 Free Games with Extra Wilds and longer symbol stacks. During any random Free Games spin, the Bursting Wilds feature can happen on any reel and turn other symbols in the gameboard into a Wild.

8 Free Games with Extra Wilds and longer symbol stacks

You may also win instant prizes of 400x, 100x, 50x, 30x, 25x, 20x, 10x, and 5x of your bet.

The Bonus Wheel cannot be retriggered during the Free Games.

Mystery Stacked Symbols

Mystery Stacked Symbols can randomly turn into other symbols anywhere on the gameboard. Respin with Locking Mystery Stacks feature triggers with any matching Mystery Symbols stacked on reels 1 and 2 in the base game.


Re-spin with Locking Mystery Stacks Feature reveals Mystery Stacked Symbols. The matching stacked symbols lock on reels 1 and 2.

If you win in this spin, you get paid. If not, you get another respin with the additional reels 3, 4, and 5. So it will go on until you hit a win.

Legend of Helios: Our Opinion

Legend of Helios is a medium-volatility slot game. RTG doesn’t disclose this value.

The graphics are detailed and, by RTG’s standard, fantastic. The backdrop is mundane, with sunny Mediterranean scenery, stone pillars, golden statues, and trees. However, the tons of special features can be very rewarding. If you’re looking for a game with substance, excitement, and playability, you’ll want to try Legend of Helios. It’s the perfect escape from the mundane grind of daily life. It’s a fast-paced, history-based journey with plenty of gambling action to keep you on the edge of your seat. Fortunately, players from the USA are also welcome to play in the online casinos where Legend of Helios is available. Nevertheless, the game description sounds complicated, so it would be better to try the slot yourself.

It is available for download or no download for all platforms and anywhere with a Wi-Fi connection or mobile internet.

Very Good
