Giant Gems is a video slot experience created by the provider Nextgen Gaming. In this Giant Gems slot review you’ll learn about its core features (including RTP, max win, and volatility), the bonus mechanics, and what helps the game stand out — along with the areas where it may fall short.
Giant Gems is played on a 5 reel layout with up to 10 paylines/ways. The game includes a variety of features such as Colossal Symbols, Fortune Spins, and more. This game does not include a free spins bonus — a feature that has become standard in most modern online slots.
The standard RTP (Return to Player) for Giant Gems slot is 96.13% (Could be lower on some sites). This payback is good and considered to be about average for an online slot. Theoretically, this means that for every €100 put into the game, the expected payout would be €96.13. However, the RTP is calculated on millions of spins, which means that the output for each spin is always random.
The highest possible payout for this slot is 500x your total bet which is rather low and can not give you the really big wins but often have a higher frequency of small wins instead. The maximum possible win is also calculated over a huge amount of spins, often one billion spins.
