This latest game in Ainsworth’s Premium Plus series features an expanding reel set that uses all of the 32-inch vertical top-box monitor of the high-end A560 SL cabinet.

The base game is available in 50-line or 100-line versions, and plays out on a three-by-five reel set. There is an optional two-level mystery progressive jackpot. In a new special feature recently introduced for the Premium Plus series, the game includes a “Sweet Zone” feature both in the primary game and in the free-spin feature.

At random, Sweet Zones appear over portions of the second and fourth reels. If a buffalo symbol lands in a Sweet Zone, wild symbols explode across adjacent reels. If buffalo symbols appear in both sweet zones, the entire game array transforms into wild symbols.

When the main bonus event is triggered, the reel set expands to nine symbols per reel, covering the vertical LCD monitor. The Sweet Zone feature applies during free spins as well, potentially transforming each of 45 symbols in the expanded array into wild symbols.
