Accumulative Trigger centers on the visual effect of special symbols (like Wilds or Coins) flying into an object such as a treasure chest, pot, basket, or bag located above or beside the reels. The key characteristics are 'Randomness' and 'Visual Suggestion'. While visual cues like a shaking full chest or overflowing coins create a psychological expectation that "it's about to pop," the feature usually triggers based on a random probability on each spin rather than filling a specific quota.

Hold and Respin, or 'Hold & Win', is one of the most popular core bonus game mechanics in modern slots. The essence of this feature, unlike traditional free spins, is to 'Hold' bonus symbols on the reels and 'Respin' the remaining empty spaces to fill up the screen. This system was popularized worldwide through 'Money Train 2's' 'Money Cart Bonus' and is the foundation for numerous developer-specific brand features like Wazdan's 'Hold the Jackpot™' and Playtech's 'Fire Blaze™'.
