Short, straight answers to the questions people ask most about NeuralSpark, the free puzzle collection from WizusLabs. Each question below is a heading with a self-contained answer, so you can jump to the one you need. To be clear from the top: this is a set of games built for enjoyment. NeuralSpark makes no claim that playing will improve, boost, or sharpen your memory, attention, or intelligence, and nothing here is offered as a health or medical benefit — a round only leaves you more practised at that round. Ready to try it? Open wizuslabs.com/neuralspark and play a round.
Is NeuralSpark free?
Yes. NeuralSpark is free to play, and the free tier includes every game, every difficulty, and the daily challenge. It is not a demo with a few games unlocked and the rest greyed out — the whole collection is open from the start. Free play is supported by ads, and there is an optional Pro upgrade that removes them.
Are there ads?
Yes — the free tier is ad-supported, which is how it stays free. We would rather say that plainly than claim there are no ads. If you would prefer not to see them, the optional Pro upgrade removes ads. Either way, none of the games themselves are locked behind a payment.
Do I need an account?
No. There is no account, no login, and no email to hand over. Open NeuralSpark and you are playing. Because there is no account, your progress lives on your device rather than behind a sign-in — which also means there is nothing to recover if you clear your data, since there was never an account to begin with.
Does it work offline?
Yes. NeuralSpark is offline-first. On the installed app you can play on a plane or in a tunnel with no connection at all. In the browser, once the page has loaded the games run locally, so a weak or dropped connection will not interrupt a round.
What is Pro, and what does the upgrade do?
Pro is an optional paid upgrade. It removes ads, adds unlimited hints on the handful of games that use hints, and applies a warm gold accent to a few screens. That is the whole of it. None of the actual games are locked behind Pro — if you never pay, you still have the entire collection and every difficulty.
Will NeuralSpark improve my memory or make me smarter?
No — and we will not pretend otherwise. NeuralSpark does not claim to improve, boost, or sharpen your memory, focus, or intelligence, and we offer no evidence that a puzzle app does any of those things. It is entertainment. Playing a memory game means you get more practised at that particular game — nothing more is promised. If short, varied puzzles are fun for you, that is the honest and complete reason to play.
What kinds of games are there?
NeuralSpark is a collection of short puzzle mini-games sorted into six categories the app calls practice areas: attention, memory, math, language, creativity, and spatial reasoning. Each category is a genre of puzzle, not a promise about your head — a memory game is one where remembering is the puzzle, a math game is one where the puzzle is arithmetic, and so on. Every game ships with more than one difficulty. The collection overview walks through all six.
How do I play in a browser?
Open wizuslabs.com/neuralspark, pick a category or tap the daily challenge, and play a round. There is no download and no tutorial to sit through — each game explains itself in a line or two. Once the page has loaded it runs locally in your browser.
Is there a mobile app?
Yes. NeuralSpark runs as an installed app on iOS and Android in addition to the free web build. The games are the same across platforms; only the way you tap changes. The App Store and Google Play links are on the NeuralSpark app page.
Is NeuralSpark suitable for children?
There is no age gate, and the puzzles are simple to pick up, so younger players can enjoy them. Bear in mind the free tier shows ads, as described above, so if you are setting it up for a child you may prefer the ad-free Pro upgrade. There is no chat, no social feed, and no account, so there is nothing to sign into or share.
Which devices and browsers does it work on?
The web build runs in any modern browser — Chrome, Safari, Firefox, or Edge — on desktops, laptops, phones, and tablets. The installed app supports current versions of iOS and Android. If a game feels cramped on a small screen, turning the phone to landscape usually helps.
Does it save my progress?
Yes — locally. Your scores and settings are stored on your own device, not on a server, so they survive closing the tab or the app. Because there is no account, progress is tied to the specific device and browser you play on, and clearing your data removes it.
What is the daily challenge?
The daily challenge is a single game the app picks for you each day, so you do not have to decide what to play. It rotates across the six categories, so a daily habit built on it naturally varies the kind of puzzle you meet. There is no streak counter designed to punish you for missing a day — skip whenever you like. The daily brain-workout routine guide shows how to build a calm few-minute habit around it.
