The game has 8 reels and 8 rows that make a grid of 64 symbols. You will win when you match 5 or more of the same symbols that contact either horizontally or vertically. All symbols that took part in a win disappear and trigger a reaction. Then, new symbols take their place. This lets you score unlimited wins from fewer paid spins. There is a Dynamite feature that exploded symbols and replaces them with new matching ones.

The reels take the most of the playing area with 64 symbols on each spin. On the dark background, you will see shiny gemstone in all colours and shapes. There are rolling red, orange, two green and two blue gems as well as others. Occasionally, dwarfs will boost your play with their substituting powers and multipliers. Also, dynamite sticks will land on the screen on losing rounds.
On the left of the reels are the bar with the cascades, pay-table button and balance. On the right, you see the wins, free spins number and wins. The design of the game is shiny, stylish, with Celtic knots on the cascade bar and in prevailing dark-brown. You will hear the sounds of cascades, spins, the blowing wind and the shouts of the dwarves.
The symbols in the game are 8 gemstones and diamonds. The bright green gemstone pays from 0.10x to 0.60x stake for clusters of 5 to 9 symbols. Matching 10 to 24 symbols of it gives you 0.80x to 4x stake. Land a cluster of 25 or more green gemstones to win 10 times your stake. The dark yellow gem pays from 0.15 to 20 times your stake for clusters of 5 to 25 or more symbols.
Next in value comes the sky blue gemstone. Landing 5 to 25+ of it that touch horizontally or vertically pays from 0.15 to 20 times your stake. The orange gemstone returns from 0.20 to 30 times your stake for clusters of 5 to 25+ symbols. The dark green egg-shaped gemstone pays from 0.20x to 30x stake for clusters of 5 to 25 or more.
The premium symbols include a pink diamond-shaped gem. It returns from 0.25 to 37.50 times your stake for 5 to 25+ symbols. The dark blue gemstone gives you from 0.50 to 75 times your stake for 5 to 25+ symbols. The top-rewarding gemstone is the red one in an oval shape. It pays from 1 to 250 times your stake when you match clusters of 5 to 25 or more of this symbol.
Part of the gameplay is the cascading feature that triggers on each win. The paying symbols explode and free space for new ones, which drop from above. Every time you score a win from clusters of matching symbols landed horizontally or vertically, they trigger a reaction. It continues as long as new winners form.
There is a dwarf symbol and this is the wild. It substitutes for all missing symbols and can take part in more than one win at a time. The dwarf wild doesn’t instantly disappear after contributing to a win. It simply moves to an adjacent space and stays there until the gaps on the grid get filled with new symbols as a result of a win. If it doesn’t take part in another win it will leave the screen.
Each wild symbol holds a multiplier that will be applied to any win it takes part in. The multiplier starts at 1x and increases by 1 with each move of the wild after taking part in a win. If you get more than one wild contributing to the same combination, their values are multiplied by each other.
The Dynamite feature can activate after any non-winning spin or cascade. When it does, one or a few dynamites will move to the symbol area and explode. This way they will replace all symbols in their location with new gemstones, which will be of the same type. This grants you a win or more from the matching symbols
If you score 5 or more re-spins or cascades after a single paid one, you activate the Free Spins. You will see the progress bar on the left panel and it shows how many winning cascades you have so far on that spin. You need 5, 6 or 7 consecutive winning cascades to trigger 6, 7 or 8 free spins, respectively.
At the start of the free rounds, you will receive 3 dwarf wilds positioned on random places on the grid. They will take part in wins and every time each wild does, its multiplier increases by +1. The more beneficial factor is that wilds don’t leave the grid even after a non-winning spin/re-spin. They simply move to adjacent positions and help you score wins boosting them with their multipliers. The 3 wilds will be present on the grid until the end of the free spins.
Gustav Minbuster has similar mechanics to Jammin’ Jars’ by Push Gaming. Still, its theme and design are completely different. Those of you who like the mining and gems themes will be pleased.
