What's Your Sign?

You control a cursor, clicking to select plus or minus symbols to fill in blanks between numbers. The main goal is to make each equation balance correctly. You might have a line like "3 ? 2 ? 1 = 4," and you need to pick the right combination of plus and minus signs to make it true. The puzzles start easy but gradually introduce longer sequences, requiring you to think a few steps ahead. The pace is methodical, without a timer, letting you work through the logic at your own speed. It feels like quietly untangling a knot in your mind.
