Game Rules
Machine Gun Nellie Rules
Machine gun nellie is played on a 7×7 grid. Wins are awarded when clusters of 5 or more adjacent matching symbols land. The symbols must be adjacent horizontally or vertically (not diagonally), winning symbols (except 
) will be removed from the reels and new symbols will fall from above. After any new wins are awarded, the winning symbols will disappear again. The process is repeated until there are no more winning combinations left on the reels.
Multiplier Hotspots Feature
When a winning symbol is removed, its place becomes a marked hotspot on the grid. X If a winning symbol is removed from the same hotspot again, a multiplier is added to the hotspot, starting at x2. The multiplier doubles each time another winning symbol is removed from a hotspot, up to a maximum of x128. The multiplier applies to all winning combinations containing a hotspot, except for .wins where a winning combination contains multiple hotspots, the multipliers from the hotspots are added together. The multipliers are updated until the last cascade and reset with the next spin.
Bank Vault Feature
If a winning combination includes a wild, the Bank Vault feature is activated. The Bank Vault feature is activated once for any number of wilds involved in winning combinations. The wheel appears above the reels before new symbols are dropped.
Spin the wheel to win a modifier:
- Double Whammy – duplicates the win on the screen with a trigger combination
- Global Upgrade – doubles all multipliers on hot spots.
- Win-Ferno – 3-5 fire jokers are randomly added to empty positions from winning combinations associated with the joker.
- Sniper Jokers – 2-5 Fire Jokers will be randomly added with the next cascade.
- Shotgun Upgrade – A random 2×2 or 3×3 area will be chosen to upgrade Hotspots from x2 to x5. Existing multipliers will increase, and normal positions will become Hotspots with the selected multiplier.
Fire Jokers act like Jokers, but do not activate the Bank Vault feature.
