Cluster Pays eliminates fixed paylines in favor of adjacency matching algorithms on expanded grids (e.g. 7x7 or 8x8). A winning payout is triggered whenever 5 or more identical symbols touch along horizontal or vertical edges. Typically paired with cascading/avalanche refills, winning clusters dissolve to allow upper symbols to fall, enabling multi-reaction chains on a single paid wager.

Hold & Win is a streak respin mechanic triggered by landing a specific threshold of cash coin scatters (usually 5 or 6). Upon triggering, standard symbols clear and 3 respin lives are granted. Each time a new cash coin, multiplier, or fixed jackpot symbol lands, it locks into position and resets the respin counter back to 3. The feature concludes when 3 consecutive spins fail to yield new symbols or all grid positions are filled.

Bonus Buy (also known as Feature Drop or Feature Buy) is an operator option that allows players to bypass the base game scatter trigger by paying a fixed cost multiple of their current bet stake (e.g. 100x bet). Mathematically, the Expected Value (EV) of the bonus buy closely matches the calculated payout of the free spin feature mode, though theoretical Return to Player (RTP) may fluctuate slightly compared to standard base game spins.
