Direct answer: a Sweet Bonanza round is one stake, one drop of candies, and one tumble chain that keeps paying as long as new clusters of eight or more matching symbols form anywhere on the grid - paylines do not exist in this spentime game.
Tumble evaluation: winning candies vanish and fresh symbols fall in, so a single stake can chain several payouts. Each chain restarts the count, which is why sessions feel busy compared with fixed-line slots.
Scatter trigger: four or more lollipop scatters open the free spins round. Inside it, every win can carry a multiplier bomb, and the bombs on one tumble add together before applying to that win - this is where the headline results happen.
Ante option: a bet boost raises the scatter frequency for a higher per-spin cost. Read the in-game info panel at your current stake before enabling it, and treat Sweet Bonanza Demo runs as the free way to feel the trigger rhythm first. For a different volatility profile between sessions, Boxing King is the usual slot-side switch on spentime.
