Lumosity popularised the idea of a daily brain workout, and it charges a subscription for it. If you want the same daily habit without the payment, everything below is free, needs no account and runs in a browser. It is also worth knowing what you are and are not buying with a subscription, so this covers that too.
Paid programmes group their exercises by cognitive ability. Here is the same grouping, with a free game for each.
Working memory — Dual N-Back for the hard version, Number Memory and Digit Span for the measurable one.
Attention and inhibition — the Stroop Test and Go/No-Go, the two standard laboratory measures.
Processing speed — Lightning Choice and the Blink Test.
Divided attention — Dual Tracker and Drive Safe.
Problem solving — Sudoku, Logic Grid, Lights Out and Codebreaker.
Mental maths — Arithmetic 60s and Times Tables Sprint.
Language — Word Recall, Anagram Hunt and Verbal Memory.
Spatial reasoning — Mental Rotation and Tangram Builder.
Visual memory — Visual Grid Memory and the Chimp Test.
Flexibility and switching — Sort & Count and Memory Reaction.
The full catalogue is on the all games page — more than 140 across thirteen categories.
Being fair about this matters, because the free alternative is not identical.
A curated daily sequence. You are not choosing what to play, which removes a real decision cost. The Plan Builder and the daily workout cover this here.
Normative scores. A paid programme compares you to a large user base by age. That is genuinely useful and it is not something a free site can honestly reproduce — we do not have a validated normative sample and we will not invent one.
Progress tracking across devices. Scores here live in your own browser and do not sync. The Score Tracker exports a CSV for exactly that reason.
Polish and adaptive difficulty. Paid programmes adjust difficulty continuously in ways most free games do not.
What a subscription does not buy is a cognitive benefit the free games lack. The underlying tasks are the same tasks, drawn from the same research literature.
In 2016 Lumos Labs settled with the US Federal Trade Commission over advertising claims about Lumosity, which the FTC alleged had overstated the evidence for real-world benefits. That is a matter of public record and it is the most concrete thing anyone can point to about the gap between marketing and data in this industry.
The underlying science has not changed since. Practising a cognitive task reliably improves you at that task and at closely related tasks — near transfer, which nobody disputes. Whether it improves unrelated abilities such as everyday memory or general intelligence — far transfer — is the contested claim, and the larger, better-controlled studies have mostly failed to find it.
What is well supported is an association between staying mentally and socially active and better cognitive ageing across large observational studies. That is an association, not proof that any particular game causes the benefit, and it is a perfectly good reason to build a habit around something you enjoy. We go into this properly in does brain training work.
Pick one thing you want to improve, not five. The Plan Builder turns that into a week.
Five to ten minutes a day beats an hour a week. Spacing is the best-supported principle in learning research and it applies to every task here.
Build in rest days. A seven-day plan breaks the first time life gets in the way. The Streak Planner prints one with rest built in.
Track a rolling average, not a personal best. The Score Tracker computes the trend so 'am I improving' has an answer.
Yes. Every ability a paid programme groups its exercises around has a free equivalent here — working memory, attention, processing speed, problem solving, language and spatial reasoning — with no account and no subscription.
A curated daily sequence, normative scores against a large user base, cross-device syncing and continuously adaptive difficulty. It does not give you a cognitive benefit the free games lack — the underlying tasks are the same.
Lumos Labs settled with the US Federal Trade Commission in 2016 over advertising claims about real-world benefits. It is a matter of public record.
They reliably improve performance on their own exercises. Evidence that this transfers to unrelated everyday abilities is weak and contested.
No. There are no accounts on this site at all, and nothing is locked behind one.
If the daily habit is what you want, you can have it for nothing. Pick one ability, play five minutes a day, build in rest days and watch a rolling average rather than a best. [Start with a plan](/tools/brain-training-plan).
