Ample Bonus Amount: 100 Free Spins Available
5/5
The bonus provides up to 100 free spins on ‘Zeus vs Hades: Gods of War,’ offering multiple chances to win real money. This generous number of spins gives you more opportunities to secure substantial winnings compared to smaller offers.
Max Win Limit: Limited Withdrawal Potential
3/5
The bonus has a maximum withdrawal limit of £100 on winnings from your free spins. This cap restricts the total cash you can withdraw, which affects the overall real money value of the bonus.
Great Value Bonus Cost: Just £10 to Claim
4/5
The bonus requires just a £10 deposit to claim, making it an affordable option in line with industry standards. This reasonable cost allows you to enjoy up to 100 free spins without a significant financial investment.
The slot from Pragmatic Play pits two powerful gods – Zeus, the ruler of Mount Olympus, and Hades, the lord of the Underworld – against each other in a mythological showdown. With vibrant graphics and engaging bonus features, you can enjoy a dynamic experience filled with special symbols, free spins, and multiplier boosts. This theme and gameplay make ‘Zeus vs Hades: Gods of War’ an exciting choice for fans of mythology-inspired slots.

An Average RTP Percentage: 96.07%
4/5
‘Zeus vs Hades: Gods of War’ has an RTP of 96.07%, which is just above the industry average. This slightly higher RTP offers better chances of winning, adding value to the bonus.
As a bonus expert, I find ONYX Slots’s offer to be a solid choice for new players. The generous number of free spins and a fair RTP provide good winning opportunities. However, the £100 max win limit and wagering requirements should be considered when evaluating the bonus’s overall value.
