Features
The Schulte Grid is a globally recognized attention-training method. An N×N grid is filled with numbers from 1 to N² in random order. Click them in sequence from 1 to N² as fast as you can — shorter times mean better focus.
Steps
Choose a difficulty (3×3 to 6×6). The timer does not start until you click cell 1. Click numbers in ascending order from 1. Wrong clicks flash red but incur no penalty. The timer stops when all numbers are clicked and a rating is shown. Each completed round is saved locally.
Rating (5×5)
Lightning (<30s): excellent focus; Excellent (<45s); Good (<70s); Keep Trying (≥70s). Best times for each size and the latest 10 records are shown in the history area, persisted via IndexedDB.
