Solvanta NexusCard

Solvanta NexusCard turns a standard card deck into three original experiences that train different mental skills, each with its own rules and scoring system.

Relay Lattice is a spatial strategy challenge. Cards become relays with directional emitters, and placing them on a grid creates links — resonance, transfer, or conflict — depending on how suits and charges interact. Building longer chains compounds their value, so every placement matters.

Field Dossier presents real-world scenarios across seven knowledge categories. You reveal evidence, eliminate wrong conclusions, and commit to a final call. Careful reasoning is rewarded: each correct elimination earns a bonus, while unnecessary evidence costs points.

Sequence Break tests pattern recognition. A row of cards follows a hidden rule — rank steps, suit cycles, colour alternation — and you identify the missing card, the next card, the odd one out, or rebuild the correct order. Every puzzle is mathematically verified to have exactly one answer.

A Daily Challenge rotates through all three experiences with a unique seed each day, tracking your streak across consecutive completions. Three difficulty tiers — Primer, Focus, and Pressure — adjust pacing, limits, and scoring across every mode.

Progress is measured on five skill axes (Strategy, Knowledge, Logic, Consistency, Composure) displayed as a personal performance profile. Fourteen milestones mark demonstrated ability rather than time spent, from your first completed run to sustained high accuracy under pressure.

The interface uses a signature chamfered card shape — two flat-cut corners opposite two rounded ones — applied consistently across every surface. All data stays in a single local file on your device.
