Bull in a China Shop is a 5-Reel video slot machine with 20 fixed paylines.

The Wild symbol (the bull), substitutes for all symbols except Scatter. When appearing, the Wild symbol will award 1 of 3 random effects: Happy bull creates 2-6 Wilds; Proud bull creates 1-5 Stacked Wilds; and Angry bull creates 2-6 x2 Multiplier Wilds. Multiplier Wild wins are not accumulative on the same payline.

The Free Spins feature is triggered by landing a Scatter symbol (the golden bull) on reel 1, 3 and 5. Choose one of the three modes: Happy Free Spins, Proud Free Spins or Angry Free Spins. An initial 10 free spins are awarded.

During Happy Free Spins, each time the Wild symbol lands, the number of Wilds created increases by 1 up to a maximum of 14. The starting number of Wilds is 2.

During Proud Free Spins, each time the Wild symbol lands, between 1-5 Stacked Wilds are created.

During Angry Free Spins, each time the Wild symbol lands, between 2-14 Multiplier Wilds are created. A multiplier of either x2, x3, x5 or x10 is randomly chosen, applying to all Wilds.

Free Spins can only be re-triggered once, with 10 additional free spins awarded. Scatter symbols are removed from the reels after re-triggering.
