8From CardGames.us to Unicorn Games: Building the Modern Web Games Platform
We are a team of two software and game developers based in the USA with a deep passion for classic gaming, logic puzzles, and delightful web experiences.
Before launching Unicorn Games, we built and continue to operate CardGames.us—a dedicated web destination focused on high-quality, pure implementations of classic card and board games like Solitaire, Hearts, Spades, and FreeCell. Alongside our web projects, we have spent years developing hit mobile applications on the Apple App Store, including the popular party game Rizz Up and the brain challenge Pic 2 Word AI.
While CardGames.us remains our beloved home for traditional card tables, we realized that players around the world were yearning for something bigger: a unified, modern web games platform that brings together classic cards, daily logic challenges, brain teasers, Sudoku, naval strategy, and casual arcade titles—with zero friction, lightning-fast load times, and uncompromising visual quality.
That vision became Unicorn Games (unicorn.games). We believe the browser is the ultimate gaming console: no 2GB app downloads, no invasive account sign-ups, and no paywalls. Just instant, beautifully crafted games designed to help you relax, sharpen your mind, and enjoy quality time on any screen.

Unicorn Games is developed and published by the same two-person development team based in the USA that created CardGames.us. While CardGames.us was founded out of our passion for classic tabletop card games (Solitaire, Hearts, Spades, Gin Rummy), our ambitions grew into building a comprehensive modern web games platform. Unicorn Games is the evolution of that vision—expanding beyond traditional cards into daily brain puzzles, Sudoku, strategy titles, and arcade classics, all running instantly in any web browser without downloads.
