Brainfool vs NonoReno

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.

NonoReno is a fully offline, procedurally generated Nonogram (Picross) puzzle game. Each puzzle you solve reveals a renovation-tool pixel icon — drill, paint roller, tape measure, tile, light bulb — collected into your gallery.
