According to Casual Girl Gamer, some difficult games to play include Increpare's "Primitive Pattern," Honeybug's "Poto and Cabenga" and "Jeu Chant" from Dabogah. GamesButler.com also notes that games such as "Hanger," "Sparta: War of Empires" and "Flying Chizard" have a high degree of difficulty.
"Primitive Pattern" is rated as the No. 1 Hardest Game by Casual Girl Gamer. It features retro graphics and is perfect for mathematically minded players. Using an algebraic algorithm, users click through nine circles in any sequence, then determine the next most likely combination based on each previous play.
To play "Poto and Cabenga," users view a split-screen of the game's heroes, named Poto and Cabenga, while navigating through a fictional plain with an evil dragon and desert critters. "Poto and Cabenga" is a one-button game that is perfect for players with strong hand-eye coordination.
"Jeu Chant" is a particularly difficult game that does not have any storyline, levels or obstacles. The game features a sliding horizontal platform, a seesaw and two silver bouncing balls. Players must slide the horizontal platform to keep one ball on the seesaw while maintaining the other suspended in air. Casual Girl Gamer recommends "Jeu Chant" for players who are good at multitasking.
