A line win is matching consecutive symbols on a win line from leftmost to right. Only the highest win per win line is paid. Winning combinations are displayed in the Paytable and reflect the current bet configuration.
Burning Baseball symbols award using scatter pays, meaning they will pay out according to the Scatter award table visible outside of the reels, irrespective of winlines.
7, 8, 9, 10 or 11 Burning Baseballs in view triggers an initial 10 seconds of free spins, and replaces the corresponding Scatter Awards with cash prizes. Landing Nicole symbols will increase progress on the meter outside the reel grid. Filling up the meter entirely will reset the timer to 10 seconds, and increase the pace of spins. Landing enough Burning Baseballs to be awarded a better Blazing Train Free Spins mode will immediately activate that mode, and replace its corresponding Scatter Award with a cash prize. There are five possible modes of Blazing Train Free Spins, activated by the amount of Burning Baseballs landed, according to this table:
| 11 | PYROCLASTIC |
| 10 | SCORCHING |
| 9 | FLAMING |
| 8 | FIERY |
| 7 | HOT |
The more Burning Baseballs required to trigger the mode, the more Burning Baseballs will be added to the reels during the bonus round.
Landing Baseball Symbols during the base game in a 2×2 square triggers 3 free spins, where the reels change to only contain Baseball Symbols, and duds. Baseball Symbols become sticky, and landing further baseballs will reset the spin counter to 3. Multiple Baseball Symbols landing in a square will create a bigger Giant Baseball. Once spins have run out, the Giant Baseballs will reveal prizes, with the bigger the Giant Baseball symbol, the bigger the potential prize value.
If the batter to the side of the reels successfully hits a Burning Baseball, 5 Home Run Spins are awarded. During Home Run Spins, Burning Baseballs will not pay out until the end of the feature. At the end of the feature, all accumulated Burning Baseball symbols landed over the course of the Home Run Spins will pay according to the award table.
