Sweet Bonanza counts matching fruit and candy symbols anywhere on the grid. Winning groups are removed and replacement symbols tumble into their positions, so consecutive wins can occur within one spin. Lollipop scatters trigger free spins, during which multiplier symbols are added together at the end of the tumble sequence. This original edition is separate from Sweet Bonanza 1000 and Super Scatter; their additional features should not be attributed to this version.
