Conveyor Belt

Words roll past — click the correct bin (or press 1/2/3) before they fall off!

How to play Conveyor Belt

Items travel along a conveyor belt from right to left. Each item must be sorted into the correct bin by clicking the matching category button before it reaches the end of the belt. The conveyor speeds up as you progress.

Sort items accurately and quickly to build your score. Items that pass the end of the belt without being sorted count as missed. The escalating speed makes this a great exercise for pushing vocabulary beyond "slow recall" to true automaticity.

Why Conveyor Belt improves your English

Conveyor Belt exercises the same cognitive skill as fluent reading: rapid pattern recognition and classification. In real language use, your brain must instantly categorise words by meaning, syntax, and context — far too fast for conscious deliberation. Conveyor Belt trains this automatic processing under pleasurable time pressure.

The physical metaphor of items moving along a belt also makes the activity viscerally satisfying — sorting things into bins triggers the same tidying impulse that makes organisation rewarding. This positive association with the activity helps learners stay engaged longer than with traditional drills.

Sorting tip: Before the belt starts, study the category labels carefully — you need to know your options instantly when items appear. Don't read items as they arrive; your eyes should already know where each category button is so your mouse/finger can move there automatically.

Vocabulary categories for Conveyor Belt

  • Parts of speech: sort words into noun / verb / adjective / adverb bins.
  • Topic categories: food, transport, clothing, technology — semantic field practice.
  • Countable/uncountable: an excellent drill for a notoriously difficult English grammar point.
  • Formal/informal register: sort words and phrases by language level.
  • Positive/negative connotation: classify words by emotional tone for nuanced vocabulary work.

Tips for Conveyor Belt success

  • Learn category positions first: Practise clicking each bin before the belt starts so your movements become muscle memory.
  • Don't over-think: If you're unsure, make your best guess and move on — overthinking causes a backlog.
  • Count your misses: A high miss rate suggests you need to review the category rules before playing.
  • Use the slowest speed first: Build accuracy at slow speed, then increase for automaticity training.

Frequently Asked Questions

How does Conveyor Belt work?
Word boxes travel from left to right along an animated conveyor belt. You must click the correct category bin — or press the corresponding number key (1, 2, or 3) — before the item reaches the right edge and falls off. Sort correctly to score points; miss or sort wrong and you lose a life.
How many rounds does Conveyor Belt have?
Conveyor Belt contains 7 rounds: Parts of Speech (noun/verb/adjective), Food/Transport/Body, Positive or Negative adjectives, Regular or Irregular past tenses, Animals/Food/Colours, Formal or Informal English, and Present or Past tense. Each round uses a different sorting criterion, covering vocabulary, grammar, and register awareness.
Does the belt speed up during the game?
Yes. The belt starts at 52 pixels per second and increases by 2 px/s with every correct sort, up to a maximum of 120 px/s. This gradual acceleration means early rounds are comfortable for learning, while later rounds challenge even experienced players to sort at genuine automatic speed.
How many items are in each round?
Most rounds contain 16–18 items, shuffled randomly each session. The Positive/Negative adjectives round and the Regular/Irregular past tense round each have 16 items. Shorter rounds like Animals/Food/Colours have 9 items. Items are always shuffled so no two play-throughs present them in the same order.
Why does time pressure help build language automaticity?
Automaticity — the ability to process language without conscious effort — is what separates fluent speakers from learners who have to mentally translate or search for words. Time pressure forces the brain to move from slow deliberate processing to fast automatic pattern recognition. Research shows that timed sorting tasks significantly reduce reaction times for vocabulary retrieval compared to untimed study.
What CEFR levels is Conveyor Belt suitable for?
Conveyor Belt covers A1 to B2 content. Parts of speech and topic category rounds suit A1–A2 learners. The Formal/Informal register round and the connotation round target B1–B2. The Regular/Irregular past tense round is appropriate from A2 onward. Teachers can direct learners to specific rounds that match their current study focus.
Does Conveyor Belt work on mobile and tablet?
Yes. The category bins are large tap targets optimised for touch screens. The belt animation and word boxes scale to fit smaller screens. On mobile, tap the correct bin button as quickly as possible — keyboard shortcuts (1/2/3) are only available on desktop but are not needed for touch play.
How is scoring calculated?
Each correct sort earns 10 points. There is no streak multiplier but the belt speed increases with accuracy, making later correct answers harder to earn. Your final score screen shows total correct sorts and an accuracy percentage. High scores are saved locally so you can track your personal best across sessions.
What tips help you sort faster without making mistakes?
Study the category labels before the belt starts — you need instant, automatic recognition of where each bin is. Keep your mouse hovering over the bin you most commonly need. Use keyboard shortcuts (1/2/3) on desktop for faster response than clicking. If you are unsure, make a quick best guess rather than hesitating; a wrong sort is less costly than a missed item.
Which LexFizz exercises are most closely related to Conveyor Belt?
Group Sort is the closest related exercise — it uses the same categorisation skill but without time pressure, making it ideal for learning a new category before attempting the belt. Whack-a-Mole and Balloon Pop share the rapid-reaction mechanic. Higher or Lower and True or False offer binary decision formats for a different kind of split-second language judgement.
