Know this game
Rolling in Treasures pays groups of matching mining symbols anywhere on a 6×5 grid, tumbles them away and assigns multipliers to replacements; in Free Spins, that progressive value stops resetting between spins.
Inside the game
A symbol must first receive a multiplier, then survive into a qualifying group. Free Spins add a third layer by preserving progression after one tumble sequence ends.
Eight or more matching symbols anywhere on the grid award a win. Adjacency and fixed paylines are not required for ordinary payouts.
Winning icons vanish and fresh symbols fall into their spaces, allowing another group to pay from the same original stake.
New symbols may begin at 2x and increase by 1x through consecutive tumbles, with qualifying values combined for the payout.
Four to six scatters start 10–20 Free Spins, where multiplier development continues from one feature spin to the next.
Whether the bonus builds early enough to use its persistent value
A win removes symbols and drops replacements. Do not treat each cascade as a separate stake; the sequence ends only when no new group pays.
New symbols can receive values beginning at 2x and rising with successive hits. Check which marked symbols join the next paying group.
Free Spins preserve progression between spins. A multiplier built in the opening turns has more remaining opportunities than one arriving near the end.

04 / The SlotsCollector take
Rolling in Treasures pays groups of matching mining symbols anywhere on a 6×5 grid, tumbles them away and assigns multipliers to replacements; in Free Spins, that progressive value stops resetting between spins.
Rolling in Treasures uses a 6×5 grid and scatter pays: eight or more matching symbols anywhere can win, then disappear so new mining icons tumble into place. The random multiplier feature marks new symbols with a starting 2x value and increases those values by 1x with each successive hit in the sequence. When several marked symbols contribute, their values are combined for the relevant result. Four, five or six bonus symbols award 10, 15 or 20 Free Spins. The important change is persistence: progressive multiplier values do not reset between feature spins, so a productive early tumble can improve the rest of the round. Retriggers add five spins, creating more time for developed values to matter. The provider labels this low volatility and publishes a 5,000x maximum. A bonus round can still be uneven because multiplier growth depends on paying tumbles and useful replacements. The 96.50% reviewed RTP applies to the available configuration. Use the demo to distinguish a multiplier being placed, increased and actually used; those are three separate events. The mining art makes progression obvious without hiding the arithmetic. Players who like cascading sessions that become stronger over time should find the bonus satisfying. Players who want every marked symbol to pay immediately may find several promising values disappear without joining a large enough group.
