Gold Trio: Sinbad's Riches Slot by Playtech

Three gold pots line up above the reels, one for each coloured coin: CASH in blue, MULTIPLY in red, COLLECT in green. Everything worth chasing runs through them. In normal play they sit there doing nothing, but land one, two or all three coloured coins and the Gold Trio Respins open.

That round is a hold-and-win built entirely on coins. Five lock to start, then the reels spin around them, and only cash prizes, the Mini/Minor/Major prize coins and whichever coloured coins set off the round can land from that point on. Every fresh coin you lock adds more respins. The coloured ones carry the real weight. A red MULTIPLY coin doubles the value on every coin showing, a green COLLECT coin scoops up all the cash prizes in view and hands you the total, and blue CASH coins just hold a figure worth up to 15x your bet. Sequence is everything: a MULTIPLY landing before a COLLECT is the run you're hoping for. Fill the entire screen with coins and the Grand drops.

Those prizes are fixed, not progressive. Mini, Minor and Major pay 10x, 20x and 50x off the Special Prize coins, while the Grand is a hefty 1,000x reserved for a full screen. If you'd rather not wait on the base game, the Buy Feature drops you straight into the respins for 50x your bet, and there's no ante option muddying the stake. Top end lands somewhere around 2,500x.

The Wild is a little sailing ship, Sinbad's boat, standing in for all but the coins and never paying on its own. Behind it sits an Arabian palace at dusk: purple horseshoe arches, golden onion domes and palm trees over a tiled courtyard, with a red-turbaned Sinbad heading a cast of a blue-veiled princess, a jewelled treasure chest, an emerald ring and crossed scimitars, all in the royal purple and gold the Gold Trio series favours.
