The signature dynamic of the tiger gems mechanics is the Hold and Win feature, triggered when six or more Bonus Gem, Boost or Mystery symbols land on a single spin. On activation the standard symbols fade away, the triggering symbols lock in place, and three respins are awarded. Every new bonus symbol resets the respin counter back to three, and the round continues until the respins run out, or until all 20 grid positions are filled, which awards the Grand Jackpot worth 1,000× the total bet.

1. Boost Feature. When a Boost symbol, which appears on reel 3 only, lands alongside one or more Bonus Gems or Mystery symbols, it instantly sums every visible gem cash value on screen and awards the total on top of any normal line wins. Because each gem value reaches 15× total bet, a densely populated screen makes Boost the most valuable non-jackpot event in the game.
2. Hold and Win respins. Sticky gems reveal values of 1× to 15× total bet. Mini, Minor and Major Jackpot symbols can also land, paying 20×, 50× and 100× respectively, with current jackpot values displayed to the left of the reels.
3. Mystery Tiger Symbol. In the base game and free spins the Mystery Tiger hides its identity until the Boost feature resolves, then transforms into a high-value Bonus Gem or into a Mini, Minor or Major Jackpot symbol.
4. Fortune Slide. During the Hold and Win round a vertical slider appears to the left of the reels, showing a queue of upcoming Bonus, Jackpot and Boost symbols. Any Mystery symbol that lands on the grid becomes the first symbol in the Fortune Slide queue, so the slider gives you partial visibility of what the next reveal will be. Watching that queue is the closest thing Tiger Gems offers to informational transparency inside a bonus round.
5. Pot Accumulation Feature. Every Bonus Gem symbol that appears in the base game and during free spins contributes to a Pot displayed above the reels. The Pot grows as gems accumulate, and it can detonate randomly during the base game, force-launching Hold and Win. That is a second, independent entry route into the bonus, since you do not always need six symbols on one spin. Because the Pot is visible, its fill level is a rough gauge of how close the game is to a triggered bonus. It is also one of the mechanics most often left out of shorter reviews of this title. Worth noting, though: a nearly full Pot is never "due".
6. Free Spins. Three Taj Mahal Scatters award 8 free spins, during which Boost, Bonus Gem and Mystery symbols appear more often. Landing three more Scatters inside the round adds another 8 spins. Free spins carry no global multiplier; their value comes from raised special-symbol density and faster Pot accumulation.
