Make 22 groups of 22. Wrong guesses just bump the mistake count.

Stacking

• Click one tile, then another to try merging them.
• Same group: they stack on the second tile. Different groups: both deselect, +1 mistake.
• Cancel without a mistake: click empty space, press Esc, or click the selected tile again.
• You can’t drag tiles. Merging onto another member of the same group is how a stack moves.
• Finished groups lock and show their category. Hover a truncated tile for the full list.

Moving around

• Scroll or use the trackpad to pan. There’s no zoom; the board is big on purpose.
• Right-click and drag anywhere on the board to pan.
• Minimap is bottom-right. Click or drag it to jump around.
