Join Capital Letters to Their Lowercase Partners

Product Description

Core Gameplay
Each puzzle shows a mixed set of capital and lowercase letters scattered on a playfield. Players must draw lines connecting each capital letter to its matching lowercase counterpart (A‑a, B‑b, etc.). Lines cannot intersect. The goal is to pair all letters correctly without crossing lines – a classic “match pairs” puzzle with an alphabet twist.

Level & Content Design
80 puzzles grouped by letter range: A‑G (7 pairs), A‑M (13 pairs), A‑Z (26 pairs). The final 20 puzzles introduce “blocked cells” where lines cannot pass. All puzzles are hand‑crafted to ensure exactly one solution. Fixed set, no live updates or expansions.

Visuals & Experience
Clean, grid‑based layout with a warm cream background. Each correct pair connects with a soft blue line that becomes solid when completed. An optional “ghost line” preview shows where a line will go before releasing the finger. Smooth rendering at 30fps to preserve battery.

Key Features

Unlimited undo per connection.

“Auto‑snap” to align lines to grid centres.

A “show unsolved pairs” button that dims already‑connected letters.

No time limits or move counters.

User Value
Reinforces letter case recognition for early learners while providing a gentle logical challenge for adults. The non‑crossing constraint trains spatial reasoning without stress.

Usage Scenarios
Helping a child practise the alphabet at a kitchen table, a short distraction during a work break, or a relaxing puzzle before a nap.
