Three Gems is a video slot game created by the provider Booongo. In this Three 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.
Three Gems is played on a 5 reel layout with up to 10 paylines/ways. The game includes a variety of features such as Scatter Pays, Stacked Symbols, Win Both Ways, 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 Three Gems slot is 95% (Could be lower on some sites). This payback is rather low and considered to be below average for an online slot. Theoretically, this means that for every €100 put into the game, the expected payout would be €95. 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 2500x your total bet which is pretty high and gives you the chance to win quite big wins. The maximum possible win is also calculated over a huge amount of spins, often one billion spins.
