MemFlip Cards

About this app

MemoryFlip is a structured working-memory trainer in the format of a classic match-the-pairs card game. Built for repeatable daily practice, with measurable progress. SCORING MODEL Final score = pairs × 100 × difficulty multiplier − time penalty (sec × 2) − excess move penalty (extra moves × 5). Every session is logged with theme, difficulty, time, moves and score, so you can compare runs over time and observe genuine improvement. DIFFICULTY TIERS • Easy — 3×4 board, 6 pairs, multiplier ×1 • Medium — 4×4 board, 8 pairs, multiplier ×2 • Hard — 5×6 board, 15 pairs, multiplier ×3 • Expert — 6×6 board, 18 pairs, multiplier ×5 CARD DECKS (THEMES) Animals · Fruits · Emoji · Vehicles · Sports · Nature. Each deck provides up to 36 distinct symbols; symbols are randomly sampled and shuffled per session to prevent positional memorization.
