Colossal Gems Slot Review

Habanero Systems in the Colossal Gems slot reconsidered the classic game of diamonds. The new version of the old device was just as easy to learn but acquired extremely interesting technical capabilities.

The slot has a space design and modern graphics. The musical accompaniment does not hurt the ears. The minimum rules make the game a suitable platform for self-learning for beginners, but even experienced users will be able to have a good time with it.

  • The RTP in the Colossal Gems slot is selected from several options presented by the developer - 91.82%, 94.00%, 96.72% and 97.88%. The first two are too low and will be perceived negatively by players, while the last one makes the game much easier. 96.72% is considered optimal and costs in most casinos.
  • The dispersion is low. This level of volatility promises frequent but insignificant winnings, sometimes not exceeding the size of the bet. To get a truly tangible combination, you will have to be patient and favor Fortune.
  • Hit frequency is above average. Considering the slot bonus for each successful symbol configuration, this is an excellent indicator!

Strategy: How to Win at Colossal Gems slot

The concept of strategy is not applicable to slots due to the complete unpredictability of the next round.

Wins can follow one after another, as well as long periods of bad luck. After a successfully played bonus, there will be no reason to be surprised by another one, although you may not see them at all even after 100 rounds. Such variability excludes the formation of a sequence of actions leading to success. All that remains is to arm yourself with one of the strategies or betting systems that can protect your balance, or even increase it.
