How the Mechanics of Slot Games Have Changed?

Slot machines have a long and rich history. It comes from the days of mechanical three-reel game layouts with just one payline. The fundamentals are the same, including spinning reels with matching symbols on the screen to win.

Modern slot games have become advanced. Although the basic concepts remain, they bear little resemblance, thanks to new changes. Online casinos in New Zealand have several of these titles and provide incentives for their new customers. One of them is like a casino with $1 NZD minimum deposit requirement with a collection of these unique and improved slot games for their customers. Each has its special creativity and innovation, changing the mechanics. This article discusses the different features that have been introduced to slot games.

Evolution of Slot Games

Slot machines have an origin that dates back to the 19th century. The first ever was known as the “Liberty Bell” by Charles Fey. Then, it had only three reels featuring mechanical drums all spinning. There was also a mechanical lever the player had to pull to put the machine into motion. The odds of winning here were based on the number of symbols appearing on each reel.

The Liberty Bell only had five symbols:

  • Diamonds
  • Spades
  • Horseshoes
  • Hearts, and
  • Liberty bell.

The early 20th century saw a change in the game’s dynamics. The electromechanical slot machine became active, offering a more dynamic gameplay than the “Liberty Bell” style. Adding the “fruit machine” across several NZ slots made symbols like oranges, cherries, and lemons a part of the game’s screen. They also had bonus rounds, allowing a player to land more wins than the earliest version.

There was also the addition of “nudging.” The electromechanical slot machine offered provisions to allow players to push the reels to influence winning combinations. It created a higher level of engagement since there was some degree to how players could influence a spin’s outcome.

The Rise of Video Slot Machines

Around the late 20th century, there was a transition from the traditional mechanic and electromechanical slot games to video machines. Rather than a physical reel screen, video options became available, increasing the dynamics and flexibility of gameplay. There was also the introduction of Random Number Generators (RNGs) to control proceedings. It became the foundation for the randomness of each spin outcome, promoting fairness.

Furthermore, video slots came with more additions for themes, bonus rounds, and animations. Multiple paylines became a regular addition, giving room for creativity. As a result, some new mechanics gave rise to inventions by game developers.

Online Slots

The popularity of the Internet gave rise to the rise of online slots. Casino sites began offering digital variants of various famous machines, allowing players to bet from their comfort place. These new versions retained the video slot mechanics but added the convenience of playing anytime, anywhere.

Top Mechanical Changes to Online Slot Games

New digital tools over the years have made the rise for new additions to slot machines. The online variants benefit the most, as developers add mechanics to instill more action layers. In turn, it has increased players’ engagement, making the game the most sought-after casino title. Here are the significant mechanics that you will find in online slot games.

Cascading Reels

The cascading reels are widespread, serving as a major alternative to the regular static reels. If you land a winning spin, the combination’s symbols disappear, allowing new ones to cascade down and fill the empty slots. This can generate multiple wins in a roll and keep the action in motion from one spin.

While many slots have cascading reels as a mechanic, Gonzo’s Quest is the first ever machine to have it. NetEnt, one of the most profitable software providers with a global reach, developed it. Other popular options worth mentioning are Reactoonz and Jammin’ Jars. Hence, you can land multiple wins directly from one spin and increase your chances of landing maximum success.


Megaways remain among the best mechanics with a high impact in today’s slot games. It is an innovation from Big Time Gaming, offering higher adrenaline levels and a chance to land a big win. Slots with this program have a dynamic number of symbols per reel, giving them up to 117,649 winning ways.

Hence, the chances of getting a reward are higher than other traditional spins. Top titles you will find this mechanic include Buffalo Rising, White Rabbit, Queen of Riches, etc. With the Megaways, the chances of landing massive wins became possible.

Expanding Symbols

Expanding symbols became a top tool for players to increase excitement and fun when wagering on slots. As its name signifies, it covers the entire reel if they land on the game screen, offering a higher chance of landing better win combinations. Some of the most popular titles with this mechanic include Starburst, Book of Ra Deluxe, Book of Dead, etc.

Mobile Slots

With the introduction of smartphones, slot games have evolved with their mechanics. Mobile slots are now standard and are among the top titles you will find for gaming from your pocket device. Thanks to their optimization, simplicity, and accessibility, players can wager at any time.

Among the adaptations, it leverages the use of touchscreens. Hence, it moves from the “one-hand bandit” time to swiping and tapping to move the reels. This transition has opened doors to new mechanics and combinations with social casino sites, where gamers can wager for free.

Final Words

The evolution of mechanics in slot games has come a long way. It moves from the “Liberty Bell” rigid stance to advanced methods of tapping “spin” to make the reels roll. All of the adaptations are due to the rise of digital innovations, which isn’t stopping anytime soon. Anyone can play on any slot of their choice, with a chance to earn bonus rounds.
