Number Span
A number flashes, then you type it back — one digit longer each round. Trains verbal short-term memory, the span you lean on for phone numbers and codes.

The workout
Six drills, each training something real
Every exercise targets a specific system — verbal span, visual-spatial recall, sequencing, list memory, concentration and attention. Short by design, so you actually come back tomorrow.
Grid Memory
Cells light up across a grid, then it goes blank and you reproduce the pattern. A direct workout for visual-spatial recall.
Sequence
Four pads play a growing order and you repeat it back. Every round adds one step, stretching sequential memory and focus together.
Word Recall
Study a short list of words, then pick them out of a crowd of look-alikes. Trains list memory the way a shopping run or a study set does.
Pair Match
Flip cards and match every pair in as few moves as you can. Rewards sustained concentration and holding positions in mind.
Colour Focus
Tap the ink colour, not the word it spells — beat the Stroop effect against the clock. Sharpens attention and processing speed.
MindFit questions
Is MindFit free?
Yes. MindFit runs in your web browser at no cost, with nothing to install.
Do I need an account to play?
Not for your first 3 games each day: open MindFit and start a drill. For unlimited games, sign in free with your Google account — it takes about 10 seconds.
Which memory games are included?
Six: Number Span, Word Recall, Grid Memory, Sequence, Pair Match and Colour Focus (a Stroop test). There is also a memory-technique library and a daily habit checklist with a streak.
Where are my scores saved?
In your browser, on this device. Best scores, your streak and any number pegs you save are not uploaded, so clearing site data or switching device starts you fresh.
How long does a session take?
Each drill is short: Colour Focus lasts 30 seconds, and the others run until your first miss. The app suggests 5–10 focused minutes a day.
Is MindFit a medical or cognitive test?
No. It is brain training for habit and fun. It does not diagnose, measure or treat any condition.
