Buzzled

Buzzled replaces squares with numbered hexagons and clues with pins planted around the honeycomb. Each pin carries a total and a color, yellow or black, and applies to a line of hexagons. You color the hexagons until the sum of the requested color exactly matches that total. A Classic daily board sits on thirty-seven hexagons surrounded by twenty-one pins, i.e. seven lines in each of the board's three directions.

1. Locate a pin and read its two pieces of information: a total and a color, yellow or black.
2. Click the hexagons on that line to turn them yellow or black; right-click cycles the colors in the opposite order.
3. Adjust until the sum of the hexagons of the requested color matches the pin's total.
4. Click a pin that has a green outline to instantly fill the still-white hexagons in its line with the other color.
5. Step back with Undo, or restart everything with Reset.

Because hexagonal geometry changes the nature of deduction: on a square grid a cell belongs to two constraints, here it serves three at once, and each move resonates in directions you hadn't been looking at. Add that the clues are about sums rather than groups, with two colors sharing the same total to reach, and you get a puzzle that looks like a beehive but reasons like an equation.

The control is visual and line by line: as soon as a line is correct, its pin gets a green outline. Because each hexagon belongs to three lines at once, a pin turning green immediately constrains two other directions. No mistake counter or penalty, only the timer at the top of the board, which can be hidden.

Mini

The entry format, described by the help panel as suitable for beginners or a quick game.

Classic

The daily format, presented as the ideal mix of challenge and relaxed play. This is the default mode.

Expert

A step above Classic according to the help panel.

Master

The mode without numbers: pins no longer indicate a sum but a number of hexagons to color. The help panel describes it as very demanding.

• Lines are not all the same length on a hexagonal board: a high sum on a short line forces almost all its hexagons, it's the best entry point.
• A green pin is not just a pat on the back; it's a tool: clicking it finishes its line with the opposite color and avoids a risky series of clicks.
• Master mode removes the numbers from the pins, leaving only a count of hexagons: a way to replay the same grid as a pure placement problem rather than a sums problem.
