Queen of the Sun is an Egyptian-themed puzzle game developed by UMARZHON, combining match-three mechanics with slot-style betting and level progression. Players match sacred artifacts on a 4x4 board, including scarabs, pharaoh masks, ankhs, hieroglyphic card symbols, and treasure chests. Lines of three or more matching symbols can earn coin payouts, with special artifacts offering x20 or x80 multipliers. Adjustable bets let players choose how much to risk on each move, while sequential levels set balance goals and challenge players to manage their coins without running out.

Unlike cascading puzzle games, each play refreshes all 16 board spaces at once. Queen of the Sun is listed as a free Android game for devices running Android 9 or later, with advertising and a 16+ age rating. The listing reports version 2.0 and more than 10,000 downloads. It also references editions for iPhone and iPad, alongside a casino-style guide. The game is presented as an independent download listing, with UMARZHON identified as its developer.
