The bonus symbols are two x2 splitting scatters, and either two bonus wilds and one x3 splitting scatter, or one bonus wild and two x3 splitting scatters. Their distribution is randomized on each new spin. All bonus symbols are frozen and need 3 winning symbols or scatters on the corresponding reel to be freed and trigger a unique effect on that reel!
Bonus wilds transform all symbols to wilds. Splitting scatters split all symbols into 2 or 3, increasing the number of ways to win. Wilds on the normal reels are included, but scatters are excluded.
3 scatters trigger frozen spins with 9 initial free spins, but each scatter awards 1 extra spin during free spins. 3 scatters on the trigger award a 5x the bet payout, while each subsequent scatter awards an additional 5x the bet payout. Scatter wins are not multiplied by the multiplier. Multiplier is carried over into, and it builds up progressively during free spins. The number of free spins and the multiplier are unlimited!
