How do bonus icons unlock big rewards in the Zeus online slot game?

The most popular Greek mythology-themed slots ever designed. The game features thunderbolt scatters, free spin bonuses, expanding wilds, and the chance to win one of four enticing progressive jackpots. At the heart of Zeus are its two high-paying bonus icons – Zeus himself and the Sphinx. Matching these symbols in groups leads to the slot’s most lucrative rewards.

Power of Zeus

The symbol carries more weight than the iconic Zeus. As king of the Greek gods, lightning bolts and thunder accompany his presence. On the reels, Zeus emerges as an overlapped image of two identical profiles facing opposite directions. The god of sky and lightning appears only on the second, third, and fourth reels.  For online slot players, seeing Zeus is electrifying. Hitting just two Zeus symbols alone delivers a rewarding 25 coins. But matching three Zeus faces triggers his most powerful reward. This awards a set number of free spins determined by how many scatters triggered the bonus initially.

During the free bro138 games, a special expanding wild Zeus is added to reels. It stacked wild locks in place and expanded to fill the entire reel, replacing all symbols with wilds for huge hit potential. The growing wild stays on that reel for the remainder of the spins. Free games also retrigger to add even more expanding wild Zeus icons. This bonus allows players to rack up massive combo wins from the proliferating wilds as Zeus displays his godly powers.

Unlocking the sphinx’s riddles

The Sphinx serves as the second high-tier bonus icon gracing the 5 reels of Zeus. With the head of a woman, the body of a lion, the wings of an eagle, and the tail of a serpent, the Sphinx was known for its intelligence and riddles.  The Sphinx appears on reels 2, 3, and 4. It functions similarly to Zeus granting 10 free spins for 3 matches. But during the Sphinx bonus, a unique 3×3 mini-reel is added to the play area.

This separate grid spins after each Zeus reel spin, awarding cash prizes, multipliers up to 10x, or extra free spins. These are all tallied above the main reels. The Sphinx mini-game creates two layers of potential win combinations as players win on both reel sets. With multipliers and extra spins in play, the Sphinx free games lead to exponential rewards. The wise Sphinx unlocks generous fortunes through its engaging bonus round.

Hitting the mega jackpot

Beyond the base game and two marquee bonuses lies one final epic jackpot – the Mega Jackpot. With a guaranteed minimum of $1 million, this life-changing prize grows as players across the casino network contribute small portions of their bets.  The odds of randomly hitting the Mega Jackpot paylines combination sit at an almost impossibly slim 1 in 50 million! But someone eventually beats those micro-odds and takes home the million-dollar+ windfall. Zeus offers three smaller Major, Minor, and Mini jackpots with better odds to hit as well, but the Mega sits as the crown jewel.
