Brainfool is a minimalist daily logic puzzle: one active brain game at a time.
Open the app and get a board—Sudoku, Takuzu (binary), Nonogram / Picross, or Slitherlink—chosen for you. Finish or bail, then get a sharp little send-off. Unfinished boards carry across days; the next puzzle arrives only after you clear or bail.
· One game at a time—not an endless brain-training gym
· Fully offline; progress stays on your device
· Difficulty quietly adapts—no badges, no mode picker
· Streak shields, month calendar, and gallery keep the habit gentle
No leaderboards, no friends list, no fill-in hints. Just this one logic puzzle.
