Lava Gold by Betsoft is a 5x5 cluster-payout slot set on a volcanic island with dinosaur-themed symbols. The game uses no fixed paylines; wins are formed by clusters of five or more matching symbols, which then disappear as new symbols fall into place. This cascade mechanic can create additional winning combinations in a single spin.
The Volcano symbol acts as a wild and can substitute for other symbols to help complete clusters. A lava meter tracks progress through winning clusters of the regular symbols in order. When the meter is filled, the game awards 10 free spins.
During the free spins round, the central column is replaced by an identical symbol, guaranteeing a win on that line, while each spin increases the multiplier from 1x up to 10x. Players can use the demo version to play for free and practice before playing for real money.
