Landing 3 shield scatters simultaneously triggers the Free Spins feature and gives you a 1x stake prize. You spin a free spin wheel which determines the number of free spins (between 10 and 30) and the multiplier (2x or 3x) for those spins. You can re-trigger the feature meaning up to 60 free spins with your initial multiplier. This feature can be re-triggered infinitely. Scatter masks can appear during Free Spins so you could win 2,000x stake prizes on every free spin.
