What is Bells & Whistles?
Bells & Whistles is a logic puzzle that splits the nonogram into two symbols. Instead of filling cells with a single mark, you place either a bell or a whistle. Row clues describe groups of bells, column clues describe groups of whistles. The daily puzzle uses a nine-by-nine grid with a timer, Undo, Reset, and a help button.
How to play Bells & Whistles
Read the two sets of clues. Row labels identify bell groups, and column labels identify whistle groups. Groups with the same label cannot touch.
Click a cell to place a bell. Click again to change it to a whistle, and a third time to clear it.
Right-click to cycle backward, starting with a whistle.
Click a row or column label to reverse the input order for that line.
Use Undo to go back one step, or Reset to clear the grid.
Feedback
A label turns green when its row or column contains the required groups. Clicking a green label fills the remaining empty cells in that line with the opposite symbol. There is no attempt limit or penalty, and you can hide the timer.
Modes
Mini is the short format, available from the button below the grid.
Classic is the daily format, with nine rows and nine columns. It opens by default.
Large uses a bigger grid and is available from the third button.
The second symbol carries its own clues rather than serving as a placeholder. Each cell informs two labels at once, one for bells and one for whistles. A nine-by-nine grid requires different reasoning than a standard nonogram, because solving a row of bells immediately constrains multiple columns of whistles.
Tips for solving
Use the cross-axis effect. Completing a row of bells fills in columns, which is where the main deduction leverage appears.
Right-click saves a step on tightly constrained columns by starting the cycle at the whistle.
Let green labels finish the work. Clicking a validated label completes the remaining cells with the opposite symbol and reduces fatigue errors.
Common questions
Do you need to dismiss the cookie banner? Yes. The banner covers the grid and blocks cell clicks until closed. It offers Disagree, MORE OPTIONS, and Agree.
Is this a nonogram? The help panel describes it as part of the nonogram or picross family, modified to use two symbols with rows and columns reading different marks.
