You will witness the first sparks of civilization being lit, and take part in humanity’s earliest journey from survival toward the dawn of civilization through dragging, combining, and inspiring cards.</p><p class="bb_paragraph" >In this demo, you can experience the game’s basic card interactions, along with the core foundation of the “Legacy” mechanics.

Cards of Sparkle Demo

<h2 class="bb_tag" ><strong>A Romantic Manifesto from Human Civilization</strong></h2><p class="bb_paragraph" >In 1977, the Voyager probes carried the &quot;Golden Record&quot; into the depths of the cosmos, bearing humanity's self-introduction to unknown civilizations. When <i>you</i>—some distant extraterrestrial being—successfully decode and run it, a grand reenactment of human civilization begins to unfold.</p><h2 class="bb_tag" ><strong>Rewrite Human Evolution, Card by Card</strong></h2><p class="bb_paragraph" >From striking the very first spark and grasping the light, you will channel humanity through cards—pushing our civilization from primal origins all the way to the stars. Every drag, every combination is a flash of inspiration: an echo of our ancestors' first questions to the world, and a quiet resonance between you and the human mind itself.</p><h2 class="bb_tag" ><strong>Light Up Civilization, One Node at a Time, Along the Tech Tree</strong></h2><p class="bb_paragraph" >Levels are no longer isolated puzzles—they are woven together along a vast tech tree. Every node you complete shapes the course of civilizations to come. A ladder-like flow of progress makes every step forward land with weight and meaning.</p><h2 class="bb_tag" ><strong>Five Great Journeys, the Turning Points of Civilization</strong></h2><p class="bb_paragraph" >Along the main path, you will encounter monumental nodes that gate the tech tree—the Journeys: Sustenance, War, the Age of Discovery, Full Automation, and the Final Reach for the Stars. Each Journey reinvents the gameplay and marks a pivotal turning point in the history of humankind.</p>
