    Who is the manufacturer of the slot machine?

    Every slot machine must be manufactured by a company that invented, designed and put it into operation. Many players eventually find that they only enjoy playing on machines from specific manufacturers, so they narrow down their selection by preferred software manufacturers. In the Czech Republic, the most popular machines are from local software manufacturers such as Kajot or Synot.

    What are the Cylinders or Reels on a slot machine?

    Reels are the basic element of most slot machines and are columns of symbols that spin and stop on the screen gradually during the game. They are therefore the basic element on which symbols spin and on which winning combinations are formed. The most popular numbers of reels are 3 and 5.

    What are paylines and how do they work?

    Paylines on slot machines are imaginary lines that run through the reels of the machine and determine which combinations of symbols on these lines are considered winning. As the reels spin, players try to achieve winning combinations of symbols on these lines. Combinations must always start from the left. Each payline has its own payout value, and the winnings are determined by the paytable for each symbol on the particular machine. Modern slot machines can have hundreds of paylines, and players often have the option to choose how many of these lines they bet on.

Slot theme and symbols

The graphics of Gem Blast are one of its strongest points, with high-quality graphics depicting sparkling gems and a backdrop inspired by the aurora borealis. The sound design complements the visual theme and increases the immersion of the game. The Diamond Star acts as a wild symbol that can substitute for all other symbols to form winning combinations. It appears on reels 2, 3 and 4 and expands to the entire reel, triggering a respin. If additional wild symbols appear during a re-spin, up to three re-spins can be awarded. One of the key features of Gem Blast is the ability to win in both directions, from left to right and right to left, effectively doubling your chances of winning.

WILD Symbol

This symbol can substitute for all other symbols in the game, helping to create winning combinations. It only appears on reels 2, 3 and 4.

Re-spin

Pros

  • The ability to win from left to right and right to left effectively doubles the chances of winning, which increases the appeal of the game.
  • The wild symbol (Diamond Star) not only substitutes for other symbols, but also expands to the entire reel and triggers respins. This can lead to a number of repeat winning chances.
  • High-quality graphics inspired by the aurora borealis and gemstones make the game visually appealing. The sound design complements the atmosphere and increases immersion in the game.

Cons

  • Unlike some other slots, Gem Blast does not offer special bonus rounds or free spins, which may be less attractive to some players.
  • The game is likely to be of medium volatility, meaning that the wins may not be as frequent or as big as on higher volatility slots. This may discourage players looking for quick, big wins.
  • The Gem Blast online slot machine does not offer any special free spins features or Scatter bonus symbols during the spins.
