The Challenge Me series is a franchise of casual puzzle games published by O-Games. The series includes titles such as Challenge Me: Brain Puzzles, Challenge Me: Math Workout, Challenge Me: Brain Puzzles 2, and Challenge Me: Word Puzzles. These games focus on stimulating cognitive skills through various logic, mathematics, and word-based challenges.
Developed during the height of the "brain training" genre popularized on the Nintendo DS, this franchise targeted casual gamers seeking daily mental exercises.
Challenge Me: Brain Puzzles (2009) debuted with popular grid-based logic games, specifically Sudoku and Picture Puzzle (nonograms). Later that same year,
Challenge Me: Math Workout (2009) shifted the focus to arithmetic, featuring modes like Hidden Logic and Formulate, which required players to construct equations from a pool of numbers.
The franchise expanded with
Challenge Me: Brain Puzzles 2 (2010), which introduced new puzzle variants such as Hanidoku and Link-a-Pix to diversify the cognitive tasks. The final entry,
Challenge Me: Word Puzzles (2011), moved away from numbers and logic grids to focus on vocabulary, offering Word Search and Conundrum modes. Across these releases, the titles utilized the Nintendo DS touch screen for direct input and featured tracking systems to monitor player improvement over time. By offering localized multiplayer modes and daily test features, the series attempted to carve out a niche in the competitive handheld puzzle market of the early 2010s.
