The all-time favourite Free Spins bonus makes a regular appearance on Booming Games slots, so there are quite a few ways one can obtain this brilliant bonus. Bonus spins are usually awarded when hitting the bonus round — the amount of spins you’re awarded depends on the Booming Games slot you play. With that said, at EnergyCasino you can also claim the Free Spins Bonus as a casino offer (EnergySpins) or through our loyalty program. Remember, Terms and Conditions apply to all bonuses, so be sure to read through them.
