Signa: Math Logic Puzzle

Every equation can be true. Only one path clears the board.

Signa is a handcrafted math-logic puzzle about finding the right equation in the right order. Connect neighboring numbers and signs, respect operation precedence, and plan ahead so every remaining block still has a valid move. A level ends only when every block in every stage is cleared.

LEARN NATURALLY
Begin with addition, subtraction, multiplication, and division one at a time. Early puzzles teach operation precedence before the campaign introduces longer chains, inequalities, and multi-stage boards.

ONE VALID MOVE
Each board state is verified to have one intended mathematical move. Solving it reshapes the board and reveals the next decision, so progress comes from logic rather than guessing. Unlimited undo lets you test an idea without losing the run.

MYSTERY OPERATORS
Some chains contain a mystery sign. Choose the only operation that completes the equation, then watch the board respond.

600 PUZZLES, 12 CHAPTERS
Difficulty grows from friendly introductions to dense multi-step challenges and long one-move finales. Comparison signs appear as occasional focused challenges instead of flooding every board with easy alternatives.

THOUGHTFUL HINTS
A hint reveals the next path and its direction on the board you actually have. Earn hints through stars and completed chapters, watch an optional rewarded ad, or choose a hint pack. Signa Pro removes automatic level-break ads while leaving optional rewarded hints available.

NO TIMER, NO PRESSURE
There is no countdown and no streak to protect. Take as long as you need on any board.
