Dynamic Schulte Variants
Nine advanced grid variants that build on the classic Schulte table — no scores here, each one opens its own trainer.
Spinning Grid
The whole grid slowly rotates — track numbers in motion.
Blinking Grid
Numbers vanish periodically — train visual memory.
Moving Targets
Cells swap places mid-round — never memorize positions.
Size-Shift Grid
Every number a different size — breaks scanning rhythm.
Letter Grid
A–Z letter sequence instead of numbers.
Honeycomb Grid
Hex cells in offset rows — no column shortcuts.
Four-Color Grid
Colors mean nothing — Stroop-style control.
Forward & Reverse
Clear 1→N, then N→1 — switch gears.
Marbles Grid
Glossy floating bubbles, gentle motion.
