Colossal Gems boasts 30 paylines which play out on a 6x5 format. The game is a fun, gem-themed adventure which is as popular with the slot purist as it is with the beginner. Bonus features include a respin on every win and a free spins feature after three consecutive respins. Both the free spins and respins feature giant gem symbols in 2x2, 3x3 and 4x4 sizes.

Game Theme & Sounds

The game is based on gems and designed in a fun, cartoonish design. Gems is a popular slot theme and one that has evolved from both diamond-themed games and video games such as Bejewelled. No one can resist a sparkling gem, which is what makes this game so visually captivating. The sci-fi muzak hybrid soundtrack is a compelling accompaniment to the game, as are the cutesy sound effects.

RTP & Variance

The game has a pretty decent RTP of 96.72% along with low volatility. This means that wins, although often small, are fairly frequent.

How to Play Colossal Gems

  1. 1. First locate the Bet Level buttons, which are found on the lower tool bar to the left of the spins button. Choose a Bet Level of 1, 2, 5, 7 or 10.
  2. 2. Now locate the Coin Amount buttons to the right of the spin button. These start at 0.01 and rise to 20.00. These amounts are multiplied by each other for the line bet and then by 30 (for the paylines) to make the total wager. The minimum line bet is therefore 0.01 and the minimum total wager is 0.30. The maximum line bet is 200, and the maximum total wager is therefore 6000.
  3. 3. Players who want to autospin can choose the Autospin button to the right of the spin button. Choose from 10 to 500 autospins.
  4. 4. Hit the ‘i’ button to the lower right of the screen to view the paytable at any time.
  5. 5. To the lower right of the screen is a volume button to turn the sounds on or off and a lightning strike icon which you can hit to turn the game to turbo mode.
  6. 6. That’s it: you’re ready to play. Hit the large spin button in the centre of the screen and watch those gems come to life.

Respins and Free Spins

Every base game win results in a respin. A winning respin results in another respin until no new wins occur or you have reached three respins. The respins feature guarantees Colossal Gems as follows:

  • 1st respin = 2x2 gem
  • 2nd respin = 3x3 gem
  • 3rd respin = 4x4 gem

A run of three consecutive respins results in triggering the free spins feature. During this feature the player enjoys six free spins and the wild purple gem enters the game (see below). Any symbols may land as 2x2, 3x3 or 4x4 size gems at any time; in fact, one of these is guaranteed with every spin.

The game also features a progressive Jackpot Race; the growing pot can be seen to the top left of the screens.

Our Review

A bold and playful game with colourful graphics and wide appeal. The things we love about this game include the mega-sized symbols (2x2, 3x3 and 4x4). These come into play in both the respin and free spins feature, both of which prove to be big earners. The gem theme isn’t new, and if you like this slot you could maybe try some alternatives such as the Royal Gems slot, which is also available to enjoy in free play mode here at Slots Temple. In fact, here at Slots Temple games our free slots are ready to play in-browser at any time, using practically any device, including a mobile. You’ll find thousands of top slot titles, including an excellent range of Habanero free play slots.
