<p>The first slot games, similar to free slots, were simple creations with basic graphics and unimpressive features. For example, most had three reels and various fruit symbols. However, as technology progressed in the 1990s, slot machine developers realized that the market was ready for a change and needed something more fun and exciting than fruit themes.</p>
<p>To attract more players, themes have become diverse and unique. On a popular slot gaming website like <a href="https://slotxo3388.com/">SlotXo</a>, you can now find hundreds of different games with impressive graphics and features.</p>
<p>However, that begs the question: how do slot machine makers come up with new themes?</p>
<h2>Where Do Slot Machine Makers Find Inspiration for New Themes?</h2>
<p>Slot machine makers use historical events, popular movies, or famous TV shows to create new themes. For example, Ancient Egypt has been an inspirational source for many slot themes. Other themes include:</p>
<h3>Historical Themes</h3>
<p>One of the most popular slot games of all time, Book of the Dead, drew inspiration from Egyptian culture. You may notice how the music, graphics, and symbols promote Ancient Egyptian tradition. If you’re a history buff, you can find several slot games inspired by historical events at <a href="https://slotxo3388.com/">SlotXo</a>.</p>
<h3>Popular Movies or TV Show Themes</h3>
<p>Another method of coming up with slot themes is to look at what movie or TV show is popular at the moment.</p>
<p>A few years ago, Game of Thrones was the #1 television show, attracting more than 13 million viewers. Microgaming saw an opportunity and came up with the Game of Thrones slot game. Narcos and Vikings are two more slot games inspired by TV shows.</p>
<h3>Retro Themes</h3>
<p>Some developers do things the old-fashioned way. Although creating slot games based on TV shows is fun, retro themes are also popular among players.</p>
<p>Starburst and Retro Reels, for example, pay tribute to the basic versions of the slot games. They attract players who feel nostalgic about the good old days and want to get a taste of their old favorite games – but with better graphics, music, and features.</p>
<h2>Popular Themes Slots for 2021</h2>
<p>There are numerous slot themes available, though some of the most popular themes for 2021 include:</p>
<h3>Asian Themes</h3>
<p>Asian slots usually feature lucky images such as gold coins, red lanterns, and lions. In addition, most of them typically include bonus games and free spins, such as must-try games like 88 Fortunes, Lights, and Lion Festivals.</p>
<h3>Adventure &; Action Themes</h3>
<p>If you are a regular slot player, you need to try at least one adventure-based slot game. You can take a trip into the wild with Rich Wilde or Lara Croft and experience what it feels like to be part of an engaging action-adventure.</p>
<h3>Crime Themes</h3>
<p>Since the first slots appeared, crime has been a popular theme. Recently, some slot machine makers released crime-themed slots, including After Night Falls, The Slotfather, Neon Staxx, and more.</p>
<p>SlotXo offers various slot-themes games to satisfy multiple needs. From adventure to history, crime, and popular TV shows, the website has it all to ensure you have a positive gaming experience.
