Boo has pretty simply gameplay with just multipliers wilds in the base game. However, a multiplier-fest in the free spins round has the potential to really crank up the payouts.
Reactions / Cascades After Each Win
Many studios call them cascades. BTG choose to call them reactions.
Whatever, it’s the same deal. After every win, winning symbols are removed from the grid. Remaining symbols drop down to fill any spaces, before new ones drop in from above to complete the grid. In a nice twist, the new ones that drop in will always be ghosts, wilds or scatters (not low value symbols).
If they create more winning combinations then the reactions keeps happening until no new wins are made.
Wilds With Up To 4x Multipliers
The wild is shown as a multi-colored ghost. He can substitute for any symbol except the scatter to help you to complete win ways.
Wilds can only appear on reels 2, 3, and 4 but they MAY land with a multiplier of up to 4x to be applied to any win they are part of.
Wild symbols with 2x and 3xFree Spins With Persistent, Progressive Multipliers
That’s the base game. Simple, but things heat up considerably in the free spins round. This is triggered by landing 3 or more scatters (the halloween pumpkin). That gets you 12 spins.
The fun part is, now EVERY position on the grid has its own multiplier which persists throughout the round. And every time a winning combination that features a premium or a wild symbol is made (only on spins, not reactions) one or more of the winning positions will have their multiplier increased by 1, 2 or 3.
NOTE: The positions on the grid where triggering scatters landed for the free spins round start with multipliers of 2x, 3x or 4x rather than 1x.
These multipliers are applied ONLY to the ghost symbols or the wilds in any win.
Finally, by landing 3 more scatters during the round you extend the round by 3 spins and increase the multiplier on each scatter position by 1x, 2x or 3x.
