Goblin's Gluttony of Gems Slot by RealTime Gaming

The bonus trigger here splits into a decision. Three or more Mine Trolley scatters drop you onto a SELECT YOUR FEATURE screen with two free games paths, and both run for 6 spins. The Goblins option locks expanding wild goblins onto reels 2 and 4 for the entire round, so every spin starts with two full columns already covered and the middle reel doing all the combination work. The Golden Coins option takes a different route: reel 5 holds coin symbols across all three positions for the whole feature, meaning every spin that lands enough coin triggers in the base columns converts instantly into a Hold and Spin. Retriggers are possible on both paths. Two distinct goblin characters act as the wilds - a snarling gold medallion on one, a meaner green-faced one on the other - and either expands to cover its entire reel whenever any part of the symbol lands.

The Hold and Spin runs separately from free games. Six or more Golden Coins anywhere on the reels kicks it off with 3 respins, the standard reset-on-new-coin rule, and a grid that's been stripped of everything except coin landings. Each coin carries a cash value, and two of those coin types are Minor and Major jackpots. The Grand sits behind one condition: fill every position of the 5x3 grid with coins before your respins run out. Fifteen positions, 3 respins refreshing each time, no easy path there but the mechanic is at least transparent about what you're chasing.

Base game is a fixed 50-payline setup with a paytable that breaks the usual RTG pattern - the BOOM! bomb premium actually outpays the pink crystal gem, 800x for five against the crystal's 500x. The grid sits under a wooden mine scaffold with rope pulleys strung across the top, a hanging lantern on the left and a pickaxe-and-shovel rig on the right. The cavern backdrop glows with pink and green crystal clusters on cool purple rock, and the card-suit lows are carved into gemstone shapes to match. No buy option, which on a game with two separate bonus triggers means you're waiting for natural drops either way.
