Siren's Riches

Siren’s Riches by Red Tiger is a video slot played on a 5-reel, 4-row grid with 50 fixed paylines. The theme blends Greek mythology and underwater fantasy, casting mermaids (sirens) beside wrecked ships and moonlit waterfalls for a darkly beautiful oceanic atmosphere. The central mechanic is a 15-spin cycle: during spins 1-14 you collect Nobleman symbols that land only on the middle reel to fill a Treasure Meter, and on the 15th spin you trigger the Siren’s Treasure bonus which activates all unlocked rewards together. Throughout that cycle, every second step along the Treasure Meter rewards things like guaranteed Wild symbols, extra Wilds, the Siren Queen Super Wild, and multipliers. The Siren Queen is a Super Wild that appears stacked, covering all four positions of the middle reel during the 15th spin once it is unlocked; it may carry a 2×, 3× or 5× win multiplier depending on how far the Treasure Meter has been advanced. Respins are awarded once certain meter milestones are reached (starting at step 10), during which Wilds and the Siren Queen remain locked for extra winning potential. There is no traditional free spins round; instead the 15-spin Siren’s Treasure cycle replaces that feature. Every 15 spins the meter resets and a new collection cycle begins. The maximum potential win in Siren’s Riches is very high, with top payouts reaching over twenty-two thousand times the stake when all features align.
