Persian Treasures Slot by RealTime Gaming

The multiplier meter on the left pillar does two different things depending on where you are. In the base game it climbs one step per cascade, so a three-chain win reads as 1x, 2x, 3x and pays accordingly. Drop into the Golden Lion free spins and the same meter shifts to a doubling scale - 1x, 2x, 4x, 8x, 16x - which is where the 250,000x line-bet top prize actually comes from. A five-cascade chain inside the bonus takes a mid-weight gem win and multiplies it by sixteen, and nothing caps the ladder except the stop of the chain. That single rule change is the whole point of triggering the feature.

Cascades themselves work the standard way - any winning combination explodes, symbols drop from above to fill the gaps, chains keep going until a spin lands blank. The twist during base play is that wilds can be randomly dropped onto the reels mid-cascade, not just arrive with the initial drop. So a chain that looked dead at step two can pick up an extra win when a wild lands on step three and bridges two high-value gems. The wild substitutes for everything except the Golden Lion scatter, which itself never pays a line - it exists only to count toward the bonus trigger. Three lions open seven spins, four open ten, five open thirteen, and retriggers layer extra spins onto whatever you're already running.

Two shortcut buttons sit stacked on the left cabinet frame. Bonus Bet is a toggle that raises scatter frequency for a per-spin premium, and Buy Feature puts you straight into the seven-spin round for roughly 100x your total stake - useful mostly because the trigger is slow on the base bet and the doubling multiplier is where the maths lives. A gamble round sits behind every win for anyone who wants to double or quadruple on a card guess.

The cabinet is pure Achaemenid fantasy. Two colossal lamassu statues, winged lion-bull sentinels cast in aged bronze, flank the reels on both sides with their paws forward and their tall conical crowns almost touching the top border. Braziers burn at the base corners, throwing warm orange light against a sandstone wall carved with geometric friezes. Gems sit as premium symbols - sapphire, ruby, amethyst, emerald - each one mounted in gold filigree on an inlaid card back, and the royals A-K-Q-J are drawn in bold painted script in matching jewel colours. The Persian Treasures wordmark runs vertically down the right pillar in ornate red-and-gold lettering. For more RTG titles built on the same cascade-plus-multiplier frame, Doragon's Gems works the mechanic on a different theme without the doubling bonus.
