Who would have thought the Stone Age would be so fun and lucrative? With Gem Rocks, it certainly is with its gem-encrusted rocks falling into formations that let you win big in a cascade slot game from Yggdrasil. This game features a very rocky design in a ground-moving game that is reminiscent of the Flintstones and their rocky abodes. With a 6x4 format, you are liable to win again and again, especially with 4096 paylines to win from.

The game’s cascade feature removes any completed pattern and replaces the empty space with new blocks that can trigger another win. Get successive wins and you get the golems to help you win more. The design is very rocky, to say the least. With a gem-encrusted rock frame surrounding the falling blocks and big rock mountains in the distance plus the sound of falling rocks completing the feel of this game will really make you feel like you are in the Stone Age.

The game has very easy to understand controls, with bet adjustments being made with the help of the plus and minus buttons on the coin value field. Highest bet is €50.00 while the lowest possible bet per spin is at €.10. Launch spins manually or enter hands-free play by clicking on Auto Play and choosing to spin up to 1000 spins automatically.


The rocks in this game can come in two sizes in the base game. These can carry any of 8 symbols, with the highest paying symbol being the red and gold star. Other symbols you will find on these blocks include a yellow crescent moon, a blue circle, and an inverted blue triangle. Lower paying symbols on these squares of rock include a right-side-up diamond-colored triangle, a green square, purple diamond, and golden X.

There are no bonus symbols, no scatter symbols, and no wild symbols in this game. There are however rock golems that can take the place of your blocks when you trigger these with consecutive wins. You will also find that these rocks can come in 1x1 and 2x2 sizes in the base game.


Considered the bonus round of this game is the appearance of the rock golems, which happens only when you get consecutive wins during your spin. The size of the golem changes with each consecutive win and are as follows:

  • 2 consecutive wins = 2x2 golem
  • 5 consecutive wins = 3x3 golem
  • 9 consecutive wins = 4x4 golem

The golem will take the place of any of the rocks and will give you a bigger win when it completes a pattern on the board. The golem can take on any of the gem stones that it chooses to take.
