Megaways is a revolutionary random reel modifier engine patented by Big Time Gaming and licensed to top global studios. On each spin, the mathematical algorithm independently varies the number of symbols appearing on each of the 6 reels (between 2 and 7 symbols). Multiplying the symbol counts across all 6 reels yields dynamic payways ranging from 64 up to 117,649 (or up to 1,000,000+ in expanded bonus modes).

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.

Cascading Reels (or Avalanche / Tumble) automatically remove all winning symbols from the reel grid after paylines or clusters evaluate. Upper remaining symbols fall into vacant lower spaces, and new symbols drop from above to fill top positions. If new winning combinations form, the cascade cycle repeats until no further wins occur on that single wager.
