Twin Digits

Twin Digits is a calm, focused memory matching puzzle built around digits, not symbols. Flip two face-down tiles on a 4×4 grid to reveal numbers 1–9; when both show the same value, they stay paired. Wrong picks flip closed again—so recall where each digit hides.

Each round spans eight pairs (sixteen tiles). A countdown timer pushes you to finish before it hits zero. Your score rises with each successful match and you can gain a small time-based bonus when you're quick. After a round, the results screen summarizes your outcome, final score, time left, level, and your personal best winning score saved on the device.

Level progression keeps things interesting: advancing levels adjust round settings so it stays challenging while you repeat Play again. Progress and stats use local storage (works offline). Exit closes the session when you're done.

Twin Digits is for anyone who enjoys solo concentration drills, quick mental recall, and a simple, no-distraction tile match against the clock—one tap from Play to the board.
