567FSignal

567FSignal is a logic puzzle game that challenges your pattern recognition and deductive reasoning skills. Step into the role of a signal analyst and learn to read the hidden rules behind every symbol.

HOW IT WORKS

Each round presents a grid of symbol cards. Each card has three attributes: color (red, blue, green, yellow), fill state (hollow, half, solid), and border (none, thin, thick). One card is secretly designated as the target signal. Your mission is to identify it.

Tap any card to receive feedback. The system compares your selected card with the target on the attribute you know least about. A "Signal Match" tells you the two cards share that attribute. A "Signal Deviation" tells you they differ. Use each clue to narrow down possibilities and deduce the exact combination of attributes that defines the target.

GAME MODES

Tutorial Mode (Levels 1-20): A carefully curated set of levels that gradually introduces each attribute dimension. Learn the mechanics at your own pace with generous attempt limits.

Infinite Mode (Level 21+): Randomly generated puzzles with increasing complexity. Cards range from 8 to 12 per round, attempt limits tighten, and negation rules may appear, forcing you to reason about what the target is NOT.
