Multiplier Wild symbols can appear anywhere on reels 1-5 and substitute for all symbols, except Scatter symbols and Nitro symbols. These Multiplier Wilds have the same multiplier as the reel (1-5) they have landed on. Any bet line win with Multiplier Wild symbols multiplies the bet line win by 1-5 respectively. If 2 or more Multiplier Wild symbols appear on the winning bet line, then the corresponding multipliers are multiplied. For example, a winning bet line with Multiplier Wild symbols on reels 2 (x2) and 4 (x4) multiply to give a x8 multiplier.

In the main game only, 3 Scatter symbols appearing anywhere on reels 2, 3 and 4 activate 10 free spins. In Free Spins only, 3 Nitro symbols appearing anywhere on reels 2, 3, and 4, award additional Free Spins and overlay Multiplier Wilds. The overlay Multiplier Wild symbols randomly appear anywhere on reels and act as a Multiplier Wild symbol only. Only one overlay Wild symbol can appear on a reel. Collected Nitro symbols are stacked in the Nitro Collect Meter from bottom to top. The Free Spins start with the player racing against Twitch, the first opponent. After collecting 3 Nitro symbols, the game moves to the next level. The player wins a random overlay Multiplier Wild and the next racing opponent appears. If a player collects 2 Nitro symbols in one spin, and 3 Nitro symbols in the next spin, the 2 Nitro symbols remaining are carried forward and are accounted for in the next level. After collecting the final 3 Nitro symbols when racing against Bruiser, the last opponent, the player races until the end of Free Spins.
