Bonus features carry the appeal of the tiger gems slot, since they hold most of its payout value. The suite covers Scatter-triggered free spins, the Hold and Win Bonus Game, the Boost mechanic and the random Gem Pot burst described above.
Free Spins. Three Taj Mahal Scatters award 8 free spins and pay 2x the total bet straight away. During the round, extra Boost, Bonus and Mystery symbols are added to the reel strips, which measurably lifts the chance of triggering Hold and Win from inside the feature. Another 3 Scatters mid-round adds a further 8 free spins.
Boost Feature. The Boost symbol appears only on reel 3 during base play and free spins, and on the Fortune Slide during the Bonus Game. When it lands beside one or more bonus gems or Mystery symbols, every visible gem value is collected and paid on top of normal line wins. This is the mechanic that turns an ordinary spin into a mid-sized win without a full bonus round, and it is the most satisfying moment the base game offers.
Feature access, an important correction. Tiger Gems does not offer a Bonus Buy or feature-purchase option. No button lets players pay a multiple of their stake, say 80x to 100x, to jump into the bonus round, and any source describing a tiger gems bonus buy is simply wrong about this title. Feature access comes only from:
- landing 3 Scatters for Free Spins;
- landing 6 or more Bonus, Boost or Mystery symbols for Hold and Win;
- the random Gem Pot burst during base play.
That absence has a real strategic consequence. In titles that do sell feature access, buying the bonus compresses variance into a handful of expensive rounds, which drains a bankroll quickly whenever a purchased round pays less than its price. Because Tiger Gems removes the option, session outcomes depend on organic trigger frequency, and the safer approach is a longer run of small stakes rather than a short run of large ones. If feature-purchase mechanics are what you actually want, look to a different 3 Oaks release; the alternatives comparison further down covers two of them.
