Colossal gems are a newly released slot not sure exactly, but the provider is Habanero. You can spin from as little as 1.50 zar and playable on all devices. I actually spun this slot for 3 zar and maybe 4.50 to increase for bigger wins. Symbols on the reels are gems which are blue, light blue, green, orange, and purple which is the most rewarding symbol paying x60 your stake. The game has 30 payline so you can imagine the potential, although the winning lines are not your standard. It's seriously weird winning lines.
Now the game has a re-spin feature with colossal symbols. So, on the first spin if you create a win, a re-spin occurs. During the first re-spin a 2x2 colossal symbol will land on the reels during that spin guaranteed. If you win during the 2x2 re-spins the next re-spin a guaranteed 3x3 colossal symbol will land on the reels. If you win during the 3x3 spin, you will get the final re-spins with a guaranteed 4x4 colossal symbol and if you win during that spins the free spins feature is trigger.
You will be awarded with 6 free spins and during those spins a special purple wild symbol land on the reels and you will find more 2x2, 3x3 or 4x4 colossal symbols during each spin for big wins. I must admit on average it takes me between 20 – 35 spins to trigger the feature. My biggest win was just over x200 and the rest of the triggers on average it paid x30 – x50 my total stake which is okay.
I know now where to go for my wagering slot should I hit it big. I am planning on playing this slot with higher stakes on the next occasion.
