EchoMeld

EchoMeld is a logic puzzle game that challenges your deductive reasoning through a unique tone-to-card matching system.

Each round presents six cards, each displaying a geometric shape with directional markers and quantity indicators. The system plays a sequence of tones, where each tone corresponds to a hidden card attribute such as shape, direction, or quantity. Your goal is to deduce which attribute each tone represents and select all cards that match every attribute in the sequence.

Gameplay features include progressive difficulty across 50 levels. Early levels introduce single-attribute mappings with generous attempts to help you learn. As you advance, the number of tones per round increases, attribute chains are introduced, and the challenge intensifies. Higher levels require matching multiple attributes simultaneously, testing both memory and logical reasoning.

Visual feedback reinforces every action. Correct selections glow green, mismatches flash red with clear explanations, and each completed round displays the full tone-to-attribute mapping so you can trace your reasoning. A streak system tracks your consecutive wins, and the game adapts difficulty based on your performance.

The dark workbench-style interface creates a focused, laboratory-like atmosphere. Tone indicators display both label and attribute type, helping you build the mental mapping between sound and symbol. The game requires no internet connection, no account creation, and no special permissions.

Whether you have a few minutes or want a deep reasoning session, EchoMeld offers a satisfying loop of inference, validation, and progression. Each round is randomly generated, ensuring no two playthroughs are the same.
