Add One 1.0.0

Add One is a concise cognitive exercise designed to challenge working memory and sustained attention by requiring players to add one to each digit of a number, with 9 wrapping to 0.

The game is played under a fixed time limit, testing concentration and rapid mental processing as numbers must be transformed quickly and accurately.

The session includes score tracking, enabling players to monitor changes in immediate memory and recall skills over time.

• Mechanics: transform each digit of the shown number by adding one, with digits wrapping from 9 back to 0.
• Feedback: scores are recorded to show progress and consistency of performance.
• Example: 1095 becomes 2106 (1→2, 0→1, 9→0, 5→6).
