Cipher Bloom
Match the nine-petal target. Tapping a petal flips that petal plus every orthogonal neighbor, so plan a short sequence instead of fixing one light at a time.

Small rules. Plenty to master.
Cipher Bloom turns a compact set of clues into a satisfying chain of deductions. Read the board, rule out contradictions, and commit only when every clue supports the move. Optional daily seeds turn the same clean rules into a fresh shared challenge. Its identity comes from a distinctive objective and rule twist rather than a cosmetic reskin. A typical session lasts three to eight minutes, works comfortably with touch or keyboard, and saves progress without requiring an account.
