Inside the game
Scatter wins trigger tumbles, while attached coins enter a meter only through the symbols that actually formed those wins.
Across the six-reel, five-row board, eight or more matching symbols can pay anywhere without fixed lines. A winning group disappears for a tumble; a coin contributes only if the symbol carrying it belongs to that paid group.
Cash coins can show values up to 20x and multiplier coins up to 10x, but neither enters the meter by appearance alone.
A coin is collected only when the symbol carrying it belongs to the qualifying scatter win removed from the grid.
Four Scatters open at least ten games, and every qualifying coin remains in the running feature meter until the bonus ends.
Whether a coin-bearing symbol joins a win before tumbles end
A visible 20x cash coin or 10x multiplier is not automatically collected. Its attached symbol must be included in a valid eight-or-more scatter win.
The base-game meter pays only after cascades stop. Record which coins enter, how multipliers alter the total and how many paid tumbles develop.
Free Spins preserve collected coin values until the feature ends, giving early contributions more time to combine with later cash and multipliers.

Viking Forge has six reels and five visible rows in the reviewed player card and captured demo. Eight or more copies of a symbol can pay anywhere; a paying group clears and gives the next tumble a chance to contribute on the same spin. The coins are a conditional layer over that familiar scatter-pays loop. A printed cash or multiplier value can attach to an ordinary symbol, but only a host symbol that actually joins a winning group sends its coin to the meter. A large value sitting outside the paid group is still only potential. In ordinary play the collected values settle after the tumble sequence; in Free Spins the meter persists until the feature finishes. That makes the timing and mix of cash and multiplier coins more revealing than the largest number visible on any one board. The official rules give at least ten Free Spins with a minimum 3× payout when four Scatters land, and another five spins for three further Scatters in the round. The current exact playable card lists 96.05% RTP, Medium volatility and a 10,000× maximum. Its older intro image has four lit bolts but no written volatility class; the current named category comes from the card. The three supplied stills separate explanation from result. The first is a teaching overlay with sample coin values, not a paid 500× win. The second is a settled ordinary board with a 1× coin on a Q, a $2 virtual stake and a $200 feature-buy control; there is no collection readout. The third catches a real $0.80 base-game win during a fiery clearing animation, with a 0.1× coin shown on an A. That frame does not prove that coin was included in the paid group or that a persistent feature meter started. Players using the free demo should first locate the host symbol under each coin, then follow a complete tumble sequence before counting any collection. The mechanic is more demanding than a simple cash-on-landing slot, but its cause and effect is visible when the board is read in that order. A published maximum describes the rules' ceiling, not an outcome to expect from a short session.
