- An abacus competition is a timed contest of calculation, grouped by age.
- Children solve sums with an abacus or purely in their head, depending on the level and round.
- The most correct answers win; equal scores are separated by time.
The abacus in 60 seconds
An abacus is a frame of rods with sliding beads. Children move beads towards the middle bar to make numbers, and learn quick finger patterns for adding and subtracting. With practice, many start to “see” the abacus in their head and calculate without touching it. If you’re new to the method, our how to use an abacus guide explains the basics step by step, while our guide to the benefits of abacus for kids looks at what regular abacus practice may help children develop.
How a competition works
Competitors sit a short paper made of several rounds. Each round tests one skill, such as long addition chains, quick-fire speed sums or multiplication, and has its own time limit.
Levels by age
Children compete against others of a similar age, so every child gets a fair, well-matched contest. Sums grow longer and harder at each level.
Abacus or mental: who uses what?
Not every child learns abacus, and they don’t need to. Every question can be solved mentally. Children who use an abacus may use one in rounds marked “Abacus or Mental”; rounds marked “Mental only” are solved in the head by everyone.
| Level | Rounds | Calculation method |
|---|---|---|
| Sprout | All rounds | Abacus or Mental |
| Riser | Core Calculation, Speed Sums | Abacus or Mental |
| Riser | Flash | Mental only |
| Sprinter | Core Calculation, Speed Sums | Abacus or Mental |
| Sprinter | Flash | Mental only |
| Ace | All rounds | Mental only |
| Grandmaster | All rounds | Mental only |
How scoring works
- One point for every correct answer.
- No minus marks for wrong or skipped answers, so it is always worth trying.
- Ties are decided by the faster time. At Sprout level, only correct answers count.
Online, from home, and fair
The Abacus World Championship 2027 is held online, so children compete from home with no travel, following the same competition rules and timed format. On a computer, the screen and camera are recorded for the whole paper; on a phone or tablet, the front camera records instead. Each child gets their own randomly generated paper and one attempt, and every result is reviewed before it is published.
