Prefrontal Lab

Six short games: Schulte Grid, Stroop, N-Back, SET Logic, Neuron Counting and Code Logic, plus a daily challenge you can finish in a minute. No account, no ads.

Prefrontal Lab is a collection of short training games for iPhone. Each round takes about a minute. Open it, play one, put it away.

SIX GAMES

· Schulte Grid — Tap numbers from 1 to 25 in order. · Stroop Test — Ignore the word meaning. Choose its actual color. · N-Back Memory — Decide whether the number matches the one 1 step ago. · SET Logic — Find 3 cards whose color and shape are all same or all different. · Neuron Counting — Count every matching target shape, then submit the number. · Code Logic — Use four clues to find a three-digit code with no repeated digits.

DAILY CHALLENGE

One fixed task per day, the same for everyone. Visual Lightning, Reverse Radar, Color Override, Memory Loop, Logic Calibration, Neural Storm, Letter Maze and Expanded Grid rotate through, each finished in 60 to 120 seconds. Completing it checks in the day and builds your streak.

COGNITIVE ARENA

A continuous mixed run of Schulte Grid, Stroop, quick SET, N-Back and Neuron Counting, tracking your personal best.

Pro Subscription

Pro unlocks three things:

1. Advanced and Endless modes in all six games: · Schulte Grid: tapped numbers disappear immediately · Stroop: the colour swatches vanish — tap the written colour name instead · N-Back Memory: 2-Back, recalling two steps back · SET Logic: fill level becomes a fourth property, all-same or all-different · Neuron Counting: more similar distractors, and they move · Code Logic: four non-repeating digits

2. The full Cognitive Arena — advanced rules across all five games in rotation.

3. Long-term training history across earlier months.

Every Advanced mode gives you one complete free round first, and the Arena gives one too, before you decide.

Basic modes, the Daily Challenge, Basic Arena, this month's records and the weekly report are open to everyone — no subscription needed.
