We present to your attention Secret of the Stones slot, which will send you into the mystical world of Celts and make you work hard to unravel all the secrets of the stone garden. And if you do it, then your efforts can be generously rewarded. On this page you will find a lot of useful information, allowing you to get acquainted with the game and learn about the features in it.

Testers opinion about Secret of the Stones slot

Personally, I do not like the new HTML 5 version. Some casinos left the old one (like Casumo). I recommend playing at the bets of €2.5, €12.5 and €25. In the process of the bonus feature, you need to follow the rule for one stone from each row. There is a trick here - when you often see two scatter symbols on the first two reels without triggering the bonus feature - it means the video slot is cold and to continue gambling here is very risky. It will better to choose a total bet of 1/200 from your balance. The Secret of the Stones slot scored only 2.67 points out of 10 in the wagering ranking. Statistically, the bonus is triggered in every 133rd spin (0,75%), but the "waves" without feature can be really long. Hit frequency in the usual spins is 35.10%. During testing the maximum winning was 1 500x. The medium feature winning was 50x. The best strategy here is to do 50-70 test spins with a low bet and to look how machine behave itself. Pay additional attention to the appearing of scatter symbols. If you like this machine, you can also try to play in its clone - Secrets of Christmas video slot. Note, that a lot of casinos restrict this slot from gambling with bonus money.

At your wish, you can adjust not only the value of the bet but also vary the number of active pay lines from 1 to 25 that cross the playing field in different directions. All available symbols are arranged in three rows so that at the same time 15 images will appear on the screen, from which you need to form the pay combinations.

Symbols and payouts

WinningMost symbols (10 pieces) are card denominations and images of animals painted on stones of different colours. The card denominations refer to low-paid symbols, but they appear on the screen quite often. The other way around, they bring good payouts, but they are less likely to get into the pay combinations. In addition to them, there are two special symbols in the video slot – Wild and Scatter, which add additional functions during the game. The payment table looks so balanced, and it has no apparent distortions in one direction or another.

  • Deer can bring payouts from 25 to 1250 coins
  • Owl will please with winnings from 20 to 750 coins
  • Buffalo will give you 15 to 500 coins
  • Wolf is not as generous, but it will bring in between 10 and 300 coins
  • Snake will increase your bank from 10 to 200 coins
  • Card symbols bring from 5 to 150 coins
  • The winning combination will be counted off if it consists of 3.4 or 5 identical symbols on the active pay line and triggers from left to right from the leftmost reel. The best payoff on the pay line is paid out if several pay combinations have fallen out, the winnings for them will be summed up.
  • Wild symbol. The image of Druid is the wild symbol. During the usual spins, it replaces other pictures, except for scatter. Its appearance is possible in any place; it does not give payments on its own. The substitution that Wild symbol makes is always aimed at getting the most valuable of the possible pay combinations on any pay line.
  • Scatter symbol. If after the spin of the reels there appear at least three scatter symbols (the tree of life with the corresponding inscription), then you will get the right to free spins. This symbol also appears in any place, but it does not independently form pay combinations.

The bonus features

Before free spins begin, you will be offered to play a thematic bonus game. You will be moved to the stone garden, where you will choose from three to five stones out of the 20 available, depending on the number of fallen scatters. Each stone can add for you additional features:

  • Additional free spins in the amount of 2,3,4,5 and 10.
  • Additional multipliers x1 or x2.
  • Additional wild symbols of a deer and owl.
  • Wild Reel 2 or Wild Reel 4
  • In our opinion, the most advantageous feature will be the pay combination of an additional ten free spins, Wild Reel 4 and Wild Reel 2 allowing you to expect a serious winning.


As for me, I enjoyed and appreciated this game. I recommend this video slot for everyone. You would like to know why I am fond of this game. The answer is easy; it has an incredible relaxing aura, complemented by a calm, and almost magical soundtrack with colourful graphics in the form of stones with masks. Green and brown shades accurately recreate Celtic atmosphere. If you like video slots which are similar to Secret of the Stones slot machine, these games have high dispersion and are endowed with one, but a mega-profitable bonus function, then this slot machine will be suitable for you perfectly. Having received a bonus round with additional wild reels, you will be on the right way to a fantastic winning. I advise you to play this slot machine at least for virtual money. The unique atmosphere will involve from the first minute of the game process, especially if you are the fan of the mysterious structures which are full of secrets.
