Why randomizing what you study can actually help

Studying one subject in a long, uninterrupted block feels productive, but research on 'interleaved practice' suggests mixing between topics can improve long-term retention compared to studying one thing at a time. A study topic wheel makes it easy to enforce that mixing without having to manually track what you've covered.

It also removes the low-level decision fatigue of picking what to study next every time you sit down — list everything you need to cover, and let the spin decide the order.

Common uses

Where this wheel fits

📚

Exam prep across multiple subjects

List each subject or chapter and spin to decide what to review next.

🔁

Interleaved practice

Mix between topics rather than studying one exclusively, which some research links to better retention.

⏱️

Timed study sprints

Spin for a topic, study it for a set block of time, then spin again for variety.

🧠

Review session variety

Keep review sessions from feeling repetitive by randomizing which material comes up.

Why Spinzelvo

Built to just work

01

Loads in under a second

No trackers, no ad auctions slowing your first paint. The wheel is interactive the moment the page appears.

02

Unlimited, resizing entries

Add 5 entries or 500 — labels shrink and wrap automatically so the wheel stays readable at any size.

03

Elimination mode built in

Flip one switch and each winner drops off the wheel, so you can run a full bracket without retyping entries.

04

Real randomness, shown honestly

The wheel spin is driven by the Web Crypto random source, not a fixed animation — every spin is independently fair.

How it works

Three steps, no account

01

Type or paste your entries

One per line in the entries box, or quick-add them one at a time. Duplicate an entry to weight the odds in its favor.

02

Press spin

Click the wheel, tap the Spin button, or hit the spacebar. The wheel decelerates naturally and lands on one entry.

03

Get your result

The result appears on a card with confetti, gets logged to your history, and — if elimination mode is on — comes off the wheel.

FAQ

Good to know

Should I weight topics I'm weaker in more heavily?

Yes — add weaker topics to the list more than once so they come up more frequently in your rotation.

Can I use this to randomize practice questions instead of topics?

Yes — list specific question types or practice sets as entries instead of broad subjects.

Is interleaved practice better than blocked studying?

Some research suggests interleaving can improve long-term retention over blocked practice for certain material, though it can feel less immediately comfortable — check your own study needs and any guidance from your course.

Can I track which topics I've already covered today?

The winner history log shows a timestamped list of recent spins, which can serve as a simple session log.
