Tiger Train Slot by BigPot Gaming

Three bonus layers stack on top of each other here, and each one feeds into the next. Scatters on reels 1, 3, and 5 start the Sticky Reels round with 8 free spins. During those spins, 0-2 positions lock each turn, and every locked position displays the same randomly chosen symbol - so if the game picks the golden lion medallion, all sticky spots show lions. Landing 2 sticky symbols on a single spin adds 3 more spins to the counter. Coin Scatters also appear during this mode, and if 6 or more accumulate (across the base game or the sticky round), the Hold&Spin triggers on top of it.

For 85x your bet, the buy option skips straight into the Sticky Reels round. The Hold&Spin itself starts with 3 respins, resetting to 3 every time a new coin lands and locking it in place. No intermediate payouts - everything tallies when the respins run dry. But there's a third layer: if a Mystery Train symbol appears during Hold&Spin, it locks alongside the coins and, once the respins end, activates the Mystery Train Bonus. That bonus converts its winnings into Heavy Coin Scatters, which pay on top of whatever the regular coins already collected.

Dark copper pipes and riveted iron panels border the grid, and a mechanical white tiger - glowing blue gem eyes, gold-plated armor, crimson boiler - serves as the locomotive parked to the right of the reels. The symbols sit in heavy metallic housings: shield-mounted lion heads, baskets of gold coins, antique compasses, and steampunk gemstones in red, purple, and teal. Card royals are stamped in brushed steel with green jewel inlays. Behind everything, a hazy industrial skyline fades into warm sunset light.

The Wild is a tiger head emblem restricted to reels 2 through 5, which means reel 1 never produces one. Fifty paylines on a standard 5x3 grid, left-to-right only. The three-stage bonus chain - sticky symbols feeding Hold&Spin feeding Mystery Train - is where the 5,000x ceiling sits, and getting there requires all three stages to fire in sequence during a single bonus entry.
