QZBrain: Brain Training Games

A calm five-minute brain workout: five games chosen for you, at the difficulty you choose. fully offline. Just quiet daily practice.

A calm daily practice for everyday sharpness. Five curated games, about five minutes, at the difficulty you choose. Fully offline. YOUR DAILY WORKOUT One tap starts a five-game session built for you — about five minutes, no repeated games, and it runs at the difficulty level you pick. When it ends, you are done. Nothing nags you to keep going.

NINE ADAPTIVE GAMES, THREE AREAS • Memory — Matrix Recall, Pattern Focus, Path Memory, Number Flow, Emoji Match, Reverse Recall • Attention & Speed — Matrix Scan • Numbers — Rapid Math (with +, −, ×, and ÷ that unlock as you level up) and Set Shift

Every game has its own adaptive staircase: succeed and it steps up, slip and it eases off. Four difficulty tiers, Novice to Expert, unlock as your performance earns them.

CALM BY DESIGN Memory games are untimed. You complete each board at your own pace — no countdown ticking over your shoulder. Sessions are short and self-contained, so QZBrain fits into your day instead of taking it over.

ONE HONEST SCORE NeuroIndex condenses each session into a single number from 100 to 999, built from your speed, accuracy, consistency, and the level you reached. It measures your progress in these games — it is not an IQ score and not a clinical measure, and we will never pretend otherwise.

SEE YOUR PROGRESS The Insight tab keeps the picture simple: a 30-day average, your weekly trend, a per-game breakdown, and the Milestones you have earned. Personal bests are tracked for every game.

ARCADE MODE When you want a looser run, Arcade is survival play: keep the clock alive as long as you can and chase your best run. It stays separate from your training history.
