Find the next number.Train your brain.

A Schulte table is the simplest test there is: tap 1 through N, in order, as fast as you can. Schulte Grid PLUS turns that one mechanic into four training modes that build peripheral vision, short-term memory, and sustained attention — fully offline, no account required.

MODE: CLASSIC · 5×5 00:00.0
Tap 1 to begin

One grid. Four ways to break a sweat.

Each mode isolates a different cognitive skill — pick one, or rotate through all four in a session.

MODE_01

Classic

Find numbers 1 to N in order, against the clock. The baseline test of visual search speed.

MODE_02

Blind Memory

The grid hides after your first tap. Recall the remaining positions from memory alone.

MODE_03

Peripheral Vision

Fix your gaze on a center crosshair and locate targets using only side vision.

MODE_04

Interference

Apply a rule — odds only, primes, Fibonacci — and filter the right number out of the noise.

What training actually looks like

Pick a size, set a rule, and the timer starts the moment you tap. Every session ends with a full performance breakdown.
