Play Global Star : Sudoku Fever Online

I picked up Global Star: Sudoku Fever for the Game Boy Advance back when it was new. It was a 2005 release from Global Star Software, a time when the GBA was full of puzzle games trying to capture some of the Brain Age crowd. This one was just a straightforward Sudoku game, no big license or characters attached. It felt like a quiet, focused title among more colorful platformers and RPGs.

You control the cursor with the D-pad, moving from square to square on the 9x9 grid. Your main job is to fill the entire board so that each row, column, and 3x3 box contains the digits 1 through 9 exactly once. The game gives you a set of starting numbers, and you use the face buttons or Select to pencil in small notes or commit a final number. You can also erase mistakes. The difficulty ramps up steadily from gentle warm-ups to some genuinely tough puzzles that require a lot of note-taking and logic. It feels methodical and satisfying when a difficult grid finally clicks into place.
